Includes:
- (Upstream) LVBase64NodeStream: fix possible segfault
- (Upstream) Fix getting encoding from HTML META tags
- FB2: also look for cover in <src-title-info>
- FB2: fix cover image colors
- FB2: don't draw cover in scroll mode
- TextLang: better linebreaks at em-dash (EN/ES/FR)
- TextLang: increase _lb_props static array size
FB2 footnotes style tweaks: avoid gap above first footnote,
caused by the title bottom margin collapsing into it.
This change to the parser in `cloudstorage.lua` adds support for the [Apache WebDAV module][1]
It was manually tested using the [bytemark/webdav][2] docker container.
I developed this in Windows, with a docker container that hosted an extracted AppImage and a VNC server that I viewed using a VNC client.
I will write up my work flow at a later point.
Changes have not been tested against other webdav servers (what was this originally tested against?). Please could someone test against other webdav servers?
I also noticed a logic inversion error where we were looking for a slash at the end of the URL and if it exists, then we explicitly set `has_trailing_slash=false` - so I fixed it to set to `true`. I had to do this so that we weren't visiting the URL without a trailing slash - apache sends back a 301 redirect with a `location` header with a trailing slash, if you don't put a trailing slash.
As a side note, I think we should consider replacing this regexp pattern matching parser with the [XML parser in the newsreader plugin[3]

* deduplicate code on warmth/brightness swipes
if device has a small scale (e.g. warmth is going from 0..10)
* adjust warmth message
* use a smaller gesture sensitivity
* bump crengine: reworked hanging punctuation
* move setting management from ReaderTypeset to ReaderTypography
And fix initial handling of defaults being loaded as true/false
but needing to be saved as 1/0.
* fix luacheck
Add Set Frontlight/Set Frontlight warmth events to dispatcher. This allows users to set day/night profiles with different fl/warmth values as requested in #6444
there is no need to pass the caller rather just the table where the setting is located. passing the setting alone is not enough as sometimes it is nil and then you do not get a reference to its location
* 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.
Witnessed with "L/R Margins": tapping on a button
sets the value to the preset table, by reference.
Tapping the -/+ fine tuning buttons was updating
these tables in-place, in effect modifying the presets.
It doesn't do so for the FM, so the inconsistency is confusing.
Plus, if you're actively using sticky rotation, saved rotations are
ignored anyway.
Re #6420
* Allow switching to SW dithering on a HW-capable device without that being lost on boot (and, worse, left in an undithered state).
* Make sure the automagic toggles between HW/SW in the Dev menu are properly saved.
Avoid conflicts having "In-page EPUB footnotes (smaller)"
affects FB2 documents that use "<a type=note>12</a>" which
would then get smaller if both tweaks are enabled (which
they are, by default).
Also switch "-cr-hint: strut-confined" from being set on "*"
to being set only on "body", now that it is inherited.
Footnote popups: add styles for some non-HTML FB2 tags,
so MuPDF can render them as expected.
