Much easier to deal with thanks to the cleanup work done in #10062 ;).
* `carrier` is set to 1 as soon as the device is *administratively* up (in practice, as soon as we run `ifconfig up`). This is perfectly fine for `isWifiOn`, but absolutely not for `isConnected`, because we are not, actually, connected to *anything*, no attempt at associating has even been made at that point. Besides being semantically wrong, in practice, this will horribly break the connectivity check, because it expects that `isConnected` means we can talk to at least the LAN.
* Delving into the Linux docs reveals that `operstate` looks like a better candidate, as it reflects *operational status*; for Wi-Fi, that means associated and successfully authenticated. That's... closer, but still not it, because we still don't have an IP, so we technically can't talk to anything other than the AP.
* So, I've brought out the big guns (`getifaddrs`), and replicated a bit of code that I already use in the USBNetwork hack on Kindle, to detect whether we actually have an IP assigned. (Other approaches, like `/proc/net/route`, may not be entirely fool-proof, and/or get complicated when IPv6 enters the fray (which it does, on Kobo, Mk. 8+ devices are IPv6-enabled)).
TL;DR: Bunch of C via ffi, and `isConnected` now returns true only when the device is operationally up *and* we have an IP assigned.

cervantes kindle kobo remarkable: use sysfs carrier file to determine connection state
cleanup hasWifiManager checks
gateway check: use ip if available
Fixes: #10087Closes: #10092
isWifiOn for kindle currently returns if the interface is connected, change this to doing what is says isWifiOn the file is only present if the wireless interface is up.
isConnected pings the gateway, rely on the kernel for a more reliable check.
Whan connecting to my android phone's wifi hotspot to remote debug from my phone, the network is connected yet the phone(gateway) does not respond to pings leading koreader to shut down the connection thinking it is unsuccessful
Apparently, toggling the rtc interrupt doesn't quite work on some boards? (fix#10031)
(Drive-by tweak to UIManager: Less confusing logging when quit gets tripped both via quit
and _gated_quit (i.e., on poweroff))
Fix#10020, Regression since #10008
(hasMultiTouch is set by `Generic.init`, but we use it before that;
so just set it properly ourselves in our superclass, because we don't
actually need to rely on Generic's autodetection).
Generic is responsible for setting up the translation via input hooks;
since our own input hooks involve swapping or mirroring X/Y, we need to
run our own hooks *first*, so that the viewport translation actually
does the right thing...
Probably broken for a good long while, I'd just assumed the inaccuracies
on the H2O were due to the IR grid... :/.
Reported @ https://www.mobileread.com/forums/showthread.php?t=351340
Regression since #9902, because I'd forgotten that the default Kobo block *does* set those...
Reported by @ptrm on Gitter, thanks!
Take two, essentially revert 8a16518918
We have defaults for most of those in the Kobo superclass, so these can never really be `nil`.
If Wi-Fi is restored on resume, going back to suspend while the
screensaver is shown via the screen_saver_lock flag would have attempted
to suspend *without* killing Wi-Fi first.
This implodes on the vast majority of NTX boards, so take the usual
precautions.
* 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.
Adjust image colors for PocketBook color devices to supply
brighter image colors. Make it a config option so we can
adjust it to a sensible default for all devices later.
Also enable HW Dithering for color devices: the dithering
flag allows us to figure out if what is viewed is an
image or text. This way we can enable color rendering
or not based on the dithering flag.
It possibly historically never made it out of InkView in the past, but
apparently that's no longer the case and/or every other key behaves the
same way anyway, so it's harmless at worst.
Fix#9791
(This involves moving it to the instance object to avoid inheritance).
Pocketbook: Disable rotation_map on the Era (fix#9556)
It would appear that InkView handles the translation for us, now...
Get rid of the doc & seqtext fields, as they are not actually used (nor
are they particularly useful, the event handler's name should be pretty
self-explanatory).
Also, tweak the key_events documentation to highlight the quirks of the
API, especially as far as array nesting is involved...
Random drive-by cleanup of the declarations of key_events & ges_events
to re-use the existing instance object (now that we know they're sane
;p) for tables with a single member (less GC pressure).
* Added a new plugin external-keyboard. It listens to USB events. When keyboard is plugged in or plugged out, it updates device and input configuration accordingly.
* Added new fake events UsbDevicePlugIn and UsbDevicePlugOut that are emitted when a device is connected to a book reader that plays the role of USB host. The usage of the existing events UsbPlugIn and UsbPlugOut has not changed - they are used when a reader is connected to a host. The koreader-base has a related PR for those events.
* Did a small refactoring of initialization for the modules FocusManager and InputText. They check device keyboard capabilities on their when the module is first loaded and store it. Some of the initialization code has been extracted into functions, so that we can re-initialize them when keyboard is (dis)connected.
* Initial implementation centered around text input, and tested with USB keyboards on devices with OTG support.
* Said OTG shenanigans are so far supported on devices with debugfs & the chipidea driver, or sunxi devices.
* Iterate over varargs directly via select if possible
* Use table.pack otherwise (https://github.com/koreader/koreader-base/pull/1535).
* This allows us to simplify a few Logger calls, as logger now handles nil values.
This should be fairly unintrusive, but still noticeable enough without having to watch the battery gauge like a hawk, or resort to actual monitoring via kernel logs and/or usb meter and/or multimeter...
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.
