Logger: Use serpent instead of dump (#9588)
* Persist: support serpent, and use by default over dump (as we assume consistency > readability in Persist).
* Logger/Dbg: Use serpent instead of dump to dump tables (it's slightly more compact, honors __tostring, and will tag tables with their ref, which can come in handy when debugging).
* Dbg: Don't duplicate Logger's log function, just use it directly.
* Fontlist/ConfigDialog: Use serpent for the debug dump.
* Call `os.setlocale(C, "numeric")` on startup instead of peppering it around dump calls. It's process-wide, so it didn't make much sense.
* Trapper: Use LuaJIT's serde facilities instead of dump. They're more reliable in the face of funky input, much faster, and in this case, the data never makes it to human eyes, so a human-readable format didn't gain us anything.

Clarify our OOP semantics across the codebase (#9586)
Basically:

* Use `extend` for class definitions
* Use `new` for object instantiations

That includes some minor code cleanups along the way:

* Updated `Widget`'s docs to make the semantics clearer.
* Removed `should_restrict_JIT` (it's been dead code since https://github.com/koreader/android-luajit-launcher/pull/283)
* Minor refactoring of LuaSettings/LuaData/LuaDefaults/DocSettings to behave (mostly, they are instantiated via `open` instead of `new`) like everything else and handle inheritance properly (i.e., DocSettings is now a proper LuaSettings subclass).
* Default to `WidgetContainer` instead of `InputContainer` for stuff that doesn't actually setup key/gesture events.
* Ditto for explicit `*Listener` only classes, make sure they're based on `EventListener` instead of something uselessly fancier.
* Unless absolutely necessary, do not store references in class objects, ever; only values. Instead, always store references in instances, to avoid both sneaky inheritance issues, and sneaky GC pinning of stale references.
  * ReaderUI: Fix one such issue with its `active_widgets` array, with critical implications, as it essentially pinned *all* of ReaderUI's modules, including their reference to the `Document` instance (i.e., that was a big-ass leak).
* Terminal: Make sure the shell is killed on plugin teardown.
* InputText: Fix Home/End/Del physical keys to behave sensibly.
* InputContainer/WidgetContainer: If necessary, compute self.dimen at paintTo time (previously, only InputContainers did, which might have had something to do with random widgets unconcerned about input using it as a baseclass instead of WidgetContainer...).
* OverlapGroup: Compute self.dimen at *init* time, because for some reason it needs to do that, but do it directly in OverlapGroup instead of going through a weird WidgetContainer method that it was the sole user of.
* ReaderCropping: Under no circumstances should a Document instance member (here, self.bbox) risk being `nil`ed!
* Kobo: Minor code cleanups.

Assorted bag'o tweaks & fixes (#9569)
* UIManager: Support more specialized update modes for corner-cases:
  * A2, which we'll use for the VirtualKeyboards keys (they'd... inadvertently switched to UI with the highlight refactor).
  * NO_MERGE variants of ui & partial (for sunxi). Use `[ui]` in ReaderHighlight's popup, because of a Sage kernel bug that could otherwise make it translucent, sometimes completely so (*sigh*).
* UIManager: Assorted code cleanups & simplifications.
* Logger & dbg: Unify logging style, and code cleanups.
* SDL: Unbreak suspend/resume outside of the emulator (fix #9567).
* NetworkMgr: Cache the network status, and allow it to be queried. (Used by AutoSuspend to avoid repeatedly poking the system when computing the standby schedule delay).
* OneTimeMigration: Don't forget about `NETWORK_PROXY` & `STARDICT_DATA_DIR` when migrating `defaults.persistent.lua` (fix #9573)
* WakeupMgr: Workaround an apparent limitation of the RTC found on i.MX5 Kobo devices, where setting a wakealarm further than UINT16_MAX seconds in the future would apparently overflow and wraparound... (fix #8039, many thanks to @yfede for the extensive deep-dive and for actually accurately pinpointing the issue!).
* Kobo: Handle standby transitions at full CPU clock speeds, in order to limit the latency hit.
* UIManager: Properly quit on reboot & exit. This ensures our exit code is preserved, as we exit on our own terms (instead of being killed by the init system). This is important on platforms where exit codes are semantically meaningful (e.g., Kobo).
* UIManager: Speaking of reboot & exit, make sure the Screensaver shows in all circumstances (e.g., autoshutdown, re: #9542)), and that there aren't any extraneous refreshes triggered. (Additionally, fix a minor regression since #9448 about tracking this very transient state on Kobo & Cervantes).
* Kindle: ID the upcoming Scribe.
* Bump base (https://github.com/koreader/koreader-base/pull/1524)

Misc: Get rid of the legacy defaults.lua globals (#9546)
* This removes support for the following deprecated constants: `DTAP_ZONE_FLIPPING`, `DTAP_ZONE_BOOKMARK`, `DCREREADER_CONFIG_DEFAULT_FONT_GAMMA`
* The "Advanced settings" panel now highlights modified values in bold (think about:config in Firefox ;)).
* LuaData: Isolate global table lookup shenanigans, and fix a few issues in unused-in-prod codepaths.
* CodeStyle: Require module locals for Lua/C modules, too.
* ScreenSaver: Actually garbage collect our widget on close (ScreenSaver itself is not an instantiated object).
* DateTimeWidget: Code cleanups to ensure child widgets can be GC'ed.

Refactor exporter.koplugin (#8944)
Changed:
  - select multiple targets and export to them in a single click.
  - local targets (html, json and text) now are timestamped. Exporting booknotes on already exported documents will generate a new file with all the highlights present at export time. Previous files won't be deleted.

Fixed:
  - chapters are now correctly represented in html output.
  - json issues when exporting the whole history.
  - joplin and readwise crashes when they're unable to reach the server
  - joplin update notes mechanism.
  - joplin is able to recreate the notebook if the user deletes or renames its current one.
  - highlights of read-only documents are also added when exporting the whole history (affects mostly android, might affect desktop targets)

A host of low power states related tweaks (#9036)
* Disable all non power management related input during suspend. (This prevents wonky touch events from being tripped when closing a sleep cover on an already-in-suspend device, among other things).
* Kobo: Use our WakeupMgr instance, not the class.
* WakupMgr: split `removeTask` in two: 
* `removeTask`, which *only* takes a queue index as input, and only removes a single task. Greatly simplifies the function (i.e., it's just a `table.remove`).
* `removeTasks`, which takes an epoch or a cb ref, and removes *every* task that matches.
* Both of these will also *always* re-schedule the next task (if any) on exit, since we can have multiple WakeupMgr tasks queued, but we can only have a single RTC wake alarm set ;).
* `wakeupAction` now takes a `proximity` argument, which it passes on to its `validateWakeupAlarmByProximity` call, allowing call sites to avoir having to duplicate that call themselves when they want to use a custom proximity window.
* `wakeupAction` now re-schedules the next task (if any) on exit.
* Simplify `Kobo:checkUnexpectedWakeup`, by removing the duplicate `WakerupMgr:validateWakeupAlarmByProximity` call, now that we can pass a proximity window to `WakeuoMgr:wakeupAction`.
* The various network activity timeouts are now halved when autostandby is enabled.
* Autostandby: get rid of the dummy deadline_guard task, as it's no longer necessary since #9009.
* UIManager: The previous change allows us to simplify `getNextTaskTimes` into a simpler `getNextTaskTime` variant, getting rid of a table & a loop.
* ReaderFooter & ReaderHeader: Make sure we only perform a single refresh when exiting standby.
* Kobo: Rewrite sysfs writes to use ANSI C via FFI instead of stdio via Lua, as it obscured some common error cases (e.g., EBUSY on /sys/power/state).
* Kobo: Simplify `suspend`, now that we have sane error handling in sysfs writes.
* Kobo.powerd: Change `isCharging` & `isAuxCharging` behavior to match the behavior of the NTX ioctl (i.e., Charging == Plugged-in). This has the added benefit of making the AutoSuspend checks behave sensibly in the "fully-charged but still plugged in" scenario (because being plugged in is enough to break PM on `!canPowerSaveWhileCharging` devices).
* AutoSuspend: Disable our `AllowStandby` handler when auto standby is disabled, so as to not interfere with other modules using `UIManager:allowStandby` (fix #9038).
* PowerD: Allow platforms to implement `isCharged`, indicating that the battery is full while still plugged in to a power source (battery icon becomes a power plug icon).
* Kobo.powerd: Implement `isCharged`, and kill charging LEDs once battery is full.
* Kindle.powerd: Implement `isCharged` on post-Wario devices. (`isCharging` is still true in that state, as it ought to).

[plugin] Display OPDS download titles if available (#8441)
I've found that some OPDS catalogs have multiple downloads of the same filetype, but optimized or formatted in different ways. The Title of the download is much more descriptive in this case, so I thought it would be better to display the title if available.

The OPDS catalog at https://standardebooks.org/opds is a good example. Note how entries in https://standardebooks.org/opds/new-releases have three different epub downloads, titled "Recommended compatible epub", "Advanced epub", and "Kobo Kepub epub".

6f1b70e5eb util.utf8: improve CJK character detection
Previously the CJK character detection defined only characters in the
range U+4000..U+AFFF as "CJK characters". This excludes an incredibly
large number of CJK characters within the BMP, let alone the whole two
planes dedicated to rarer CJK characters (the SIP and TIP). As a result,
a very large number of Chinese, Japanese, and Korean characters were not
detected as being CJK characters.

While slightly less elegant-looking, it is far more accurate to compute
the codepoint from the utf8 character and then see if it falls within
one of the defined CJK blocks. This is not future-proof against future
CJK ideograph extensions in future Unicode versions, but there is no
real way to accurately predict such changes so this is the best we can
do without accidentally treating characters explicitily defined as being
non-CJK in Unicode as CJK.

While we're at it, copy Lua 5.3's utf8.charpattern constant definition
so that we can more easily write utf8 iterators with string.gmatch (at
least in the interim until there is a rework of utf8 handling in
KOReader and everything is rebuilt on top of utf8proc).

Some unit tests are added for Korean and Japanese text, and the existing
unit tests needed a minor adjustment to handle the fact that
isSplittable now correctly detects CJK punctuation as a character to
compare against the forbidden split rules.

e7acec1526 ReaderUI: Saner FM/RD lifecycle
* Ensure that going from one to the other tears down the former and
    its plugins before instantiating the latter and its plugins.

UIManager: Unify Event sending & broadcasting
  * Make the two behave the same way (walk the widget stack from top to
    bottom), and properly handle the window stack shrinking shrinking
    *and* growing.
    Previously, broadcasting happened bottom-to-top and didn't really
    handle the list shrinking/growing, while sending only handled the list
    shrinking by a single element, and hopefully that element being the one
    the event was just sent to.

These two items combined allowed us to optimize suboptimal
refresh behavior with Menu and other Menu classes when
opening/closing a document.
e.g., the "opening document" Notification is now properly regional,
and the "open last doc" option no longer flashes like a crazy person
anymore.

Plugins: Allow optimizing Menu refresh with custom menus, too.

Requires moving Menu's close_callback *after* onMenuSelect, which, eh,
probably makes sense, and is probably harmless in the grand scheme of
things.

* ReaderDictionary: Port delay computations to TimeVal
* ReaderHighlight: Port delay computations to TimeVal
* ReaderView: Port delay computations to TimeVal
* Android: Reset gesture detection state on APP_CMD_TERM_WINDOW.
  This prevents potentially being stuck in bogus gesture states when switching apps.
* GestureDetector:
  * Port delay computations to TimeVal
  * Fixed delay computations to handle time warps (large and negative deltas).
  * Simplified timed callback handling to invalidate timers much earlier, preventing accumulating useless timers that no longer have any chance of ever detecting a gesture.
  * Fixed state clearing to handle the actual effective slots, instead of hard-coding slot 0 & slot 1.
  * Simplified timed callback handling in general, and added support for a timerfd backend for better performance and accuracy.
  * The improved timed callback handling allows us to detect and honor (as much as possible) the three possible clock sources usable by Linux evdev events.
    The only case where synthetic timestamps are used (and that only to handle timed callbacks) is limited to non-timerfd platforms where input events use
    a clock source that is *NOT* MONOTONIC.
    AFAICT, that's pretty much... PocketBook, and that's it?
* Input:
  * Use the <linux/input.h> FFI module instead of re-declaring every constant
  * Fixed (verbose) debug logging of input events to actually translate said constants properly.
  * Completely reset gesture detection state on suspend. This should prevent bogus gesture detection on resume.
  * Refactored the waitEvent loop to make it easier to comprehend (hopefully) and much more efficient.
    Of specific note, it no longer does a crazy select spam every 100µs, instead computing and relying on sane timeouts,
    as afforded by switching the UI event/input loop to the MONOTONIC time base, and the refactored timed callbacks in GestureDetector.
* reMarkable: Stopped enforcing synthetic timestamps on input events, as it should no longer be necessary.
* TimeVal:
  * Refactored and simplified, especially as far as metamethods are concerned (based on <bsd/sys/time.h>).
  * Added a host of new methods to query the various POSIX clock sources, and made :now default to MONOTONIC.
  * Removed the debug guard in __sub, as time going backwards can be a perfectly normal occurrence.
  * New methods:
    * Clock sources: :realtime, :monotonic, :monotonic_coarse, :realtime_coarse, :boottime
    * Utility: :tonumber, :tousecs, :tomsecs, :fromnumber, :isPositive, :isZero
* UIManager:
  * Ported event loop & scheduling to TimeVal, and switched to the MONOTONIC time base.
    This ensures reliable and consistent scheduling, as time is ensured never to go backwards.
  * Added a :getTime() method, that returns a cached TimeVal:now(), updated at the top of every UI frame.
    It's used throughout the codebase to cadge a syscall in circumstances where we are guaranteed that a syscall would return a mostly identical value,
    because very few time has passed.
    The only code left that does live syscalls does it because it's actually necessary for accuracy,
    and the only code left that does that in a REALTIME time base is code that *actually* deals with calendar time (e.g., Statistics).
* DictQuickLookup: Port delay computations to TimeVal
* FootNoteWidget: Port delay computations to TimeVal
* HTMLBoxWidget: Port delay computations to TimeVal
* Notification: Port delay computations to TimeVal
* TextBoxWidget: Port delay computations to TimeVal
* AutoSuspend: Port to TimeVal
* AutoTurn:
  * Fix it so that settings are actually honored.
  * Port to TimeVal
* BackgroundRunner: Port to TimeVal
* Calibre: Port benchmarking code to TimeVal
* BookInfoManager: Removed unnecessary yield in the metadata extraction subprocess now that subprocesses get scheduled properly.

* All in all, these changes reduced the CPU cost of a single tap by a factor of ten (!), and got rid of an insane amount of weird poll/wakeup cycles that must have been hell on CPU schedulers and batteries..
