Move as much of the state tracking as possible inside VirtualKeyboard itself.
InputDialog unfortunately needs an internal tracking of this state because it needs to know about it *before* the VK is shown, so we have to keep a bit of duplication in there, although we do try much harder to keep everything in sync (at least at function call edges), and to keep the damage contained to, essentially, the toggle button's handler.

* Enforce a minimal standby timer for the first standby after a resume.
* On Kobo, sleep a bit before standby.
This aims to alleviate race conditions causing visible refresh glitches on sunxi, especially when using an extremely low standby timer (i.e., below the defaults).
Includes:
- SVG: <epub:switch/case/default>: accept SVG
- Text: don't adjust spacing of leading no-break-space
- Block rendering: fix "break-before: always" sometimes not ensured
- Styles: parse <style> as white-space: pre
- CSS: revamp 'inherit' handling, now fully per CSS specs
- CSS/colors: handle 'transparent' as a real color
Also includes:
- android: forward play and pause to the system
wpa_supplicant returns all non-ASCII SSIDs as raw bytes in the form
\x0a. We interpret these bytes as UTF-8, and make sure that all invalid
characters are replaced with a �.
Fix issue introduced by 976aaf5f: with full screen
text editor and hiding the keyboard, a tap in the
text area would show a new keyboard hiding the
buttons allowing to save/close the text editor,
getting us stuck there.
An attempt was made in the original code, but the whole thing was designed in the hope of actually switching to turbo, so it was super janky without it.
Anyway, we now actually have a sane way to set socket timeouts, so, use that, and set them very tight for now.
This is fairly critical right now, because the server is down, and the default timeouts are ~30s. That happens to be *above* the debounce threshold, so you can't even hope for that to help you. Meaning, right now, you get a 2 * 30s block on resume with auto sync. That's... Very Not Good(TM).
That becomes a single 2s one after this.
Makes more sense this way.
Re: #10828
Also clarify the UIManager "no dialogs left" message, and drop the
return value, as it's meaningless, we just want to break & return.
Assume the host system does things right otherwise.
Should be sane on Kindle
On PocketBook, who knows, but assuming the device actually suspends,
that should effectively kill our keepalive
Irrelevant for Android, as we skipped it because the wifi toggling
methods are interactive.
Fix#10823
(For reference, we *enable* wifi_was_on no matter *how* wifi is enabled,
but we only toggle it off when it's killed by a *direct* user interaction,
the intent being that if *something* non-interactive enabled wifi,
you'll probably silently need it on resume too).
As early as turnOnWifi.
Implement it on hasWifiManager platforms, preventing useless
connectivity checks to run when they're obviously never going to work
because you're out of range of your AP.
Also implemented a flag to notify the backend if the connection attempt
was interactive or not.
Right now, interactive is extremely restricted, it basically means the
menu checkmark, or a gesture.
The intent being that for stuff like the beforeWifiAction framework, we
don't want the backend to spawn extra UI.
Specifically, for hasWifiManager platforms, we no longer spawn the AP
scan list on failure unless the caller was interactive.
TL;DR: beforeWifiAction is now much less obnoxious when you're obviously
not able to connect.
onCloseDocument is way too early, if another, later onCloseDocument
handler trips a ReaderUI repaint, a new task will be scheduled, and that
one will never be cancelled, resulting in it running post-teardown,
crashing horribly.
This was for instance very easy to trigger via KOSync.
Fix#10806
MultiInputDialog does a close -> show in the same callback,
so if we don't actually keep it in sync with the actual state, we lose
the keyboard and essentially softlock the UI, which is Very Bad(TM).
NOTE: InputDialog has its own keyboard_hidden flag, and it looks...
fairly nightmarish.
