* Handle said rotation shenanigans inside ScreenSaver & ScreenSaverWidget, which allows a more targeted approach; and prevents said rotation from affecting other widgets. (Also, gets rid of duplicated code).
* Handle the corner-case or exiting early from a "keep on screen for n sec" screensaver better, by unscheduling the extra refresh, since an early tap took care of that already.
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.)
* Only toggle nightmode via the grayscale fb info flag on Kindle
Most NTX boards require elaborate trickery (see fbdepth) to actually
send a vput ioctl without the driver screwing with the rotation behind
your back.
This was causing spurious hardware rotations on exit on most Kobo
devices, something which might have gone mostly unnoticed, as current
Nickel versions will sanitize it on startup.
A simple repro was instead to start an USBMS session, as that exits
KOReader and restarts it without going through fbdepth again ;).
* 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
screen.
Otherwise, on the Sage, weird flash glitches may happen, depending on
what was on screen...
(e.g., there's some weird update merging shenanigans going on
despite those updates being flagged NO_MERGE...).
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).
We should always unschedule suspend before scheduling it again (i.e.,
use rescheduleSuspend ;)).
Fix#8097 (many thanks to @Mel-kior for the detailed repro!)
We've managed to trip a few of those on dimen fields post-init but
pre-paintTo in a few weird coner-cases, a point at which dimen is often
nil.
ConfigDialog: Deal with that very thing in update()
Fix#7656
* 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).
* Make switching *back* to the default DPI via auto actually work
properly.
eg., by actually setting DPI back to defaults, and clearing the override
flag.
* Bump base to pickup https://github.com/koreader/koreader-base/pull/1258
* 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...
* Enable AutoSuspend plugin on rM
Fix#6769
Re: #6028
* Use the PowerEvent handler on rM
It makes much more sense than the fire & forget & hope for the best
approach copied from the Kindle platform, because we *are* controlling
suspend ourselves (mostly), unlike on Kindle ;).
Fix#6676
* Enable HW inversion on the rM
I mean, we kinda forgot to ever test that, but I don't really see why it
wouldn't work ;).
* 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
The differences between Allwinner/MXC matter surprisingly little in practice, it's not even worth
it to bother the base mxc driver with it. Instead, frontend can make some informed choice by
probing for the hardware and tweaking requested device caps accordingly.
On Allwinner B288, we disable both hwrot (done in software in kernel and terribly, ie not worth it)
and hwinverse (no support whatsoever). On NXT we'll keep both on, as the kernel driver seems
to be using the hardware properly .
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.
* Uses bunch of new plumbing in base to configure screen rotations in hardware (koreader normally does this via blit buffer rotations, except for android).
* Some PB specific kludges that used to pollute core/framebuffer_linux are brought into PBs frontend driver.
* 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
Touchscreen is mirrored in X & Y and has a different resolution from the eink panel.
Uses systemd for time/date/suspend/poweroff/reboot
Two systemd units for platform integration. button-listen is a very
simple launcher.
to-do: add support for wifi by implementing a wpa supplicant dbus client.

* Don't store stale screen/rotation modes in book's settings!
Gyro events *may* entirely bypass the local copy...
In any case, using a local copy was essentially asking for trouble...
Actually fix#5772
(because the issue was indeed that a Gyro swap from Portrait to Inverted
Portrait wasn't stored properly).
* Allow showing ScreenSavers in Inverted Portrait.
That works just fine, and won't lead to the confusing situation where a
lefty might pick up the device as a righty because the ScreenSaver
happens to be shown that way, only to have it rotate back to its lefty
orientation on wakeup...
