* Device: Add a `hasSeamlessWifiToggle` devcap to complement `hasWifiToggle`, to denote platforms where we can toggle WiFi without losing focus, as this has obvious UX impacts, and less obvious technical impacts on some of the NetworkMgr innards...
* Android: Mark as `!hasSeamlessWifiToggle`, as it requires losing focus to the system settings. Moreover, `turnOnWifi` returns *immediately* and we *still* run in the background during that time, for extra spiciness...
* NetworkMgr: Ensure only *one* call to `turnOnWifi` will actually go on when stuff gets re-scheduled by the `beforeWifiAction` framework.
* NetworkMgr: Ensure the `beforeWifiAction` framework will not re-schedule the same thing *ad vitam aeternam* if a previous connection attempt is still ongoing. (i.e., previously, on Android, if you backed out of the system settings, you entered the Benny Hill dimension, as NetworkMgr would keep throwing you back into the system settings ;p). This has a few implications on callbacks requested by subsequent connection attempts, though. Generally, we'll try to honor *explicitly interactive* callbacks, but `beforeWifiAction` stuff will be dropped (only the original cb is preserved). That's what prevents the aforementioned infinite loop, as the `beforeWifiAction` framework was based on the assumption that `turnOnWifi` somewhat guaranteed `isConnected` to be true on return, something which is only actually true on `hasWifiManager` platforms.
* NetworkMgr: In `prompt` mode, the above implies that the prompt will not even be shown for concurrent attempts, as it's otherwise extremely confusing (KOSync on Android being a prime example, as it has a pair of Suspend/Resume handlers, so the initial attempt trips those two because of the focus switch >_<").
* NetworkMgr: Don't attempt to kill wifi when aborting a connection attempt on `!hasSeamlessWifiToggle` (because, again, it'll break UX, and also because it might run at very awkward times (e.g., I managed to go back to KOReader *between* a FM/Reader switch at one point, which promptly caused `UIManager` to exit because there was nothing to show ;p).
* NetworkMgr: Don't drop the connectivity callback when `beforeWifiAction` is set to prompt and the target happens to use a connectivity check in its `turnOnWifi` implementation (e.g., on Kindle).
* Android: Add an `"ignore"` `beforeWifiAction` mode, that'll do nothing but schedule the connectivity check with its callback (with the intent being the system will eventually enable wifi on its own Soon(TM)). If you're already online, the callback will run immediately, obviously. If you followed the early discussions on this PR, this closely matches what happens on `!hasWifiToggle` platforms (as flagging Android that way was one of the possible approaches here).
* NetworkMgr: Bail out early in `goOnlineToRun` if `beforeWifiAction` isn't `"turn_on"`. Prompt cannot work there, and while ignore technically could, it would serve very little purpose given its intended use case.
* KOSync: Neuter the Resume/Suspend handlers early on `CloseDocument`, as this is how focus switches are handled on Android, and if `beforeWifiAction` is `turn_on` and you were offline at the time, we'd trip them because of the swap to system settings to enable wifi.
* KOSync: Allow `auto_sync` to be enabled regardless of the `beforeWifiAction` mode on `!hasSeamlessWifiToggle` platforms. Prompt is still a terrible idea, but given that `goOnlineToRun` now aborts early if the mode is not supported, it's less of a problem.
Make sure we only send Suspend/Resume events when we *actually* suspend/resume. This is done via the Device `_beforeSuspend`/`_afterResume` methods, and those were called by the *input handlers*, not the PM logic; which means they would fire, while the PM logic could actually take a smarter decision and *not* do what the event just sent implied ;).
(i.e., sleep with a cover -> suspend + actual suspend, OK; but if you then resume with a button -> input assumes resume, but PM will actually suspend again!).
Existing design issue made more apparent by #9448 ;).
Also fixes/generalizes a few corner-cases related to screen_saver_lock handling (e.g., don't allow USBMS during a lock).
And deal with the fallout of the main change to the Kobo frontlight ramp behavior ;).

* Get rid of the `canToggleGSensor` Device cap, it's now mandatory for `hasGSensor` devices. (This means Kindles can now toggle the gyro, fix#9136).
* This also means that `Device:toggleGSensor` is now implemented by `Generic`.
* Update the Screen & Gyro rotation constants to be clearer (c.f., https://github.com/koreader/koreader-base/pull/1568) (/!\ This might conceivably break some `rotation_map` user-patches).
* Input: Move the platform-specific gyro handling to Device implementations, and let Input only handle a single, custom protocol (`EV_MSC:MSC_GYRO`).
* Input: Refine the `rotation_map` disable method implemented in 43b021d37c. Instead of directly poking at the internal field, use a new method, `disableRotationMap` (/!\ Again, this might break some `rotation_map` user-patches).
* Input: Minor tweaks to event adjust hooks to make them more modular, allowing the Kobo implementation to build and use a single composite hook. API compatibility maintained with wrappers.
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.
Commonize fullscreen code across different devices.
Add fullscreen toggle on SDL desktop targets.
Expose the toggle to the dispatcher and map it to F11.
Hide touchmenu when resizing.
* Rejig frontlight warmth API to more closely match the existing API, and, hopefully, clarify some of its quirks, and reduce boilerplate and duplicate code in platform implementations.
* Tweak Kindle:setDateTime to prefer using the platform's custom script, as in interacts better with the stock UI. And make the fallbacks handle old busybox versions better.
* Add Kindle PW5 support ;).
* Add warmth support to the Kindle platform.
* Random TextBoxWidget cleanups: make sure we immediately free destroyed instances.
* FrontLightWidget: Refactor to make it slightly less obnoxious to grok and update; i.e., separate layout from update, and properly separate brightness from warmth handling. Move to simpler widgets instead of reinventing the wheel.
* TextBoxWidgets: Implement `setText` to match TextWidget's API, as some callers may be using the two interchangeably (i.e., Button).
* NaturalLightWidget: Make sure we pass a string to InputText
* InputText: Add debug guards to catch bad callers not passing strings ;).
Wrap document opening and re-renderings (which can block
the app for some time) with setIgnoreInput() to avoid ANR
on Android.
Any setting update that could possibly cause a re-rendering
should send the UpdatePos event, to ensure the re-rendering
happens in ReaderRolling:onUpdatePos() where precautions
are taken to avoid ANR.
The hyphenation of a word can be changed from its default
by long pressing for 3 seconds and selecting 'Hyphenate'.
These overrides are stored in a per-language file, i.e:

* 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..
* Modernize jit syntax
It's built-in, no need for a require anymore.
* Flag Android should_restrict_JIT again
It's mildly helpful at putting off the inevitable.
(very, very, very, very mildly).
* Bump android-luajit-launcher
