* 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).
* Make sure AutoStandby cohabitates nicely with AutoSuspend (regression since #8985), specifically:
* Disable standby during suspend.
* Ensure that leaving standby restores the scheduled suspend properly, with the appropriate remaining amount of time based on the last user input.
* Handle devices with an auxiliary battery better when scheduling suspend (assume it's only charging when the aux battery is charging, not the ereader's).
* Tweak debug logging to be able to remote debug corner-cases more easily without requiring code changes.
* Fix erroneous behavior when awoken from standby by something that doesn't trigger an InputEvent Event (e.g., rtc alarm, gyro, or random bullshit).
Specifically, don't forcibly unschedule/schedule on every input event, instead, let the scheduled task figure out if the deadline came to pass or not ;).

Besides getting rid of some overhead, this allows proper scheduling after a task that would have blocked for longer than the standby timeout.
Allows the device to go into standby (if available in `/sys/power/state`) to save power.
Adds an entry in the device menu to tune the timeout for standby.
(Shows total standby- and suspend-time in system statistics.)
* The first few capacity reads after connecting to the cover may fail
* The PowerCover may trigger spurious move/add usb_plug uevent,
which translate into Charging events for us.
Instead of blindly lighting up the charging LED on those,
check if the device is actually charging, first.
Implement it on the Kobo Sage, for the PowerCover
TouchMenu: Display auxiliary battery status
Kobo: More accurately report the PowerCover's charging status
i.e., try to actually figure out if the auxiliary battery is charging
instead of just checking the reader's battery (because that one will
often swap between the charging and discharging state as it drains the
aux battery...).
PowerD: Use a cached timestamp when doing battery pull checks
cores
* Only keep a single core online most of the time.
* Device: Add an enableCPUCores method to allow controlling the amount of
online CPU cores.
* Move the initial core onlining setup to Kobo:init, instead of the startup script.
* Enable two CPU cores while hinting new (e.g., cache miss) pages in PDF land.
* Enable two CPU cores while processing book metadata.
* Drive-by fix to isolate the DocCache pressure check to KoptInterface
and actually apply it when it matters most (e.g., k2pdfopt stuff).
* TimeVal: Log the results of the COARSE probes in debug logs
* GestureDetector: Print details of failed clock probes in debug logs
* GestureDetector: Skip the BOOTTIME probe when CLOCK_BOOTTIME is unsupported.
* Input: Decode ABS_DISTANCE events in debug logs
* Get rid of duplicated <linux/input.h> constants, use the FFI module everywhere (re #7536)
* Kobo: Get rid of the `touch_alyssum_protocol` quirk. Replace it by setting `main_finger_slot` to `1`, like on the H2O.
Requires https://github.com/koreader/koreader-base/pull/1344 & https://github.com/koreader/koreader-base/pull/1346 (fix#7485)
Assorted input fixes:
* Actually handle errors in the "there's a callback timer" input polling loop.
* Don't break timerfd when the clock probe was inconclusive.
Not directly related, but noticed because of duplicate onInputEvent handlers:
* HookContainer: Fix deregistration to actually deregister properly. "Regression" extant since its inception in #2933 (!).
* Made sure the three plugins (basically the trio of AutoThingies ;p) that were using HookContainer actually unschedule their task on teardown.
* Actually load librt properly on old Linux systems (fix#7472)
* Made sure SDL & Android honored timeouts properly in some edgy (or not so edgy, in SDL's case) cases (c.f., https://github.com/koreader/koreader-base/pull/1343).
* Try harder not to consume a timer callback when the timerfd backend is in use and `select` timed out *not* because of a timerfd expiring. This would take some particularly heinous timing to reproduce (e.g., a timerfd set, but a task deadline expiring *before* it). May or may not help with #7473.
* Decode `BTN_` KEY codes in verbose debug logs.
* Fix MultiTouch on the H2O (GestureDetector was hard-coding the two slots as 0 & 1, but the H2O kernel is a special snowflake that doesn't use slot 0, instead switching to slot 1 & 2).
* Unify logging with AutoSuspend (e.g., keep ourselves to showing the delay in seconds, not the raw timestamp, as that's way harder to interpret, and the RTC module and/or logger will do that for us when the time comes).
* Speaking of, minor revamp of RTC related logging to make it more human-readable.
* On Kobo, if we hit the unexpected wakeup limit, re-engage AutoSuspend's *suspend* check, so that the device has a chance to poweroff instead of being kept awake.
* Hold "Wi-Fi connection" to show network connection options.
* Honor backend connections (e.g., if wpa_supplicant found a matching AP in its own config first).
* When user clicks "Wi-Fi connection" in menu, only prompt if state is ambiguous.
* LuaSettings/DocSettings: Updated readSetting API to allow proper initialization to default.
Use it to initialize tables, e.g., fixing corner-cases in readerFooter that could prevent settings from being saved.
(Fixes an issue reported on Gitter).
* LuaSettings/DocSettings: Add simpler API than the the flip* ones to toggle boolean settings.
* Update LuaSettings/DocSettigns usage throughout the codebase to use the dedicated boolean methods wher appropriate, and clean up some of the more mind-bending uses.
* FileChooser: Implement an extended default exclusion list (fix#2360)
* ScreenSaver: Refactor to avoid the pile of kludges this was threatening to become. Code should be easier to follow and use, and fallbacks now behave as expected (fix#4418).
* Warn on restart if the startup script has been updated, because a restart will not reload it.
* Also warn right after the update if it contained a startup script update...
* Fix initial tap on the H2O
There's no slot 0, so make sure the initialState doesn't get confused by input's init data that otherwise assumes the main slot is 0
On devices where the event time is the uptime (time since
boot), we don't need to trash it and use TimeVal:now()
and lose precision. We can still use these times for
relative delays and durations computations, which is
mostly all we use them for.
We just need a real clock time in GestureDetector for
two timers (long-press and double tap), where we do
the event time type detection on the first event, on
all devices.
* In icons mode, just use two different icons to display Wi-Fi status
* Enable Wi-Fi status icon on Kobo & Cervantes, too
* Refresh footer on (dis)connect if the Wi-Fi status item is enabled
CBB now handles nightmode correctly (by deferring to Lua), so we no longer
need to do monkey dances about disabling it when hw invert is missing.
canUseCBB cap is resolved by generic device re-configuring blitbuffer
on the go, so as to avoid repeating the same thing in every device driver.
The dev setting can now flip cbb on the go, so one can gloat at the near
meaningless perf difference - 2Mp draw is 15ms Lua / 10ms C on 1GHz Cortex A7.
* Revamped most actions that require an internet connection to a new/fixed backend that allows forwarding the initial action and running it automatically once connected. (i.e., it'll allow you to set "Action when Wi-Fi is off" to "turn_on", and whatch stuff connect and do what you wanted automatically without having to re-click anywhere instead of showing you a Wi-Fi prompt and then not doing anything without any other feedback).
* Speaking of, fixed the "turn_on" beforeWifi action to, well, actually work. It's no longer marked as experimental.
* Consistently use "Wi-Fi" everywhere.
* On Kobo/Cervantes/Sony, implemented a "Kill Wi-Fi connection when inactive" system that will automatically disconnect from Wi-Fi after sustained *network* inactivity (i.e., you can keep reading, it'll eventually turn off on its own). This should be smart and flexible enough not to murder Wi-Fi while you need it, while still not keeping it uselessly on and murdering your battery.
(i.e., enable that + turn Wi-Fi on when off and enjoy never having to bother about Wi-Fi ever again).
* Made sending `NetworkConnected` / `NetworkDisconnected` events consistent (they were only being sent... sometimes, which made relying on 'em somewhat problematic).
* restoreWifiAsync is now only run when really needed (i.e., we no longer stomp on an existing working connection just for the hell of it).
* We no longer attempt to kill a bogus non-existent Wi-Fi connection when going to suspend, we only do it when it's actually needed.
* Every method of enabling Wi-Fi will now properly tear down Wi-Fi on failure, instead of leaving it in an undefined state.
* Fixed an issue in the fancy crash screen on Kobo/reMarkable that could sometime lead to the log excerpt being missing.
* Worked-around a number of sneaky issues related to low-level Wi-Fi/DHCP/DNS handling on Kobo (see the lengthy comments [below](https://github.com/koreader/koreader/pull/6424#issuecomment-663881059) for details). Fix#6421
Incidentally, this should also fix the inconsistencies experienced re: Wi-Fi behavior in Nickel when toggling between KOReader and Nickel (use NM/KFMon, and run a current FW for best results).
* For developers, this involves various cleanups around NetworkMgr and NetworkListener. Documentation is in-line, above the concerned functions.
* Allow locking the gyro to the current screen mode (i.e., orientation).
* Tweak the "sticky rota" option to work both ways
* More rotation constant usage instead of magic numbers
* generic Device:info() function which returns the model
* add Device:canSuspend() and make it true in all devices that have suspend routines and the emulator
* also enable fake poweroff/reboot on the emulator
* add Device.home_dir
* add Device:hasExitOptions() and update menus & comments
