The read/write loops may keep going for a while on a closing connection
with lots of read/write activity, as it's random which select case is
chosen. And if the connection is slow or even broken, a single
read/write
can take a long time/until timeout. Add initial non-blocking selects
with only the cases relevant to closing, to prioritize those.
This would have addressed a recent issue that arose when re-ordering our
"filesystem layers". Specifically moving the caseFilesystem to the
outermost layer. The previous cache included the filesystem, and as such
all the layers below. This isn't desirable (to put it mildly), as you
can create different variants of filesystems with different layers for
the same path and options. Concretely this did happen with the mtime
layer, which isn't always present. A test for the mtime related breakage
was added in #9687, and I intend to redo the caseFilesystem reordering
after this.

Followup to: #9687
This is to add the generation of `compat.json` as a release artifact. It
describes the runtime requirements of the release in question. The next
step is to have the upgrade server use this information to filter
releases provided to clients. This is per the discussion in #9656

This changes the two remaining instances where we use insecure HTTPS to
use standard HTTPS certificate verification.
When we introduced these things, almost a decade ago, HTTPS certificates
were expensive and annoying to get, much of the web was still HTTP, and
many devices seemed to not have up-to-date CA bundles.
Nowadays _all_ of the web is HTTPS and I'm skeptical that any device can
work well without understanding LetsEncrypt certificates in particular.
Our current discovery servers use hardcoded certificates which has
several issues:
- Not great for security if it leaks as there is no way to rotate it
- Not great for infrastructure flexibility as we can't use many load
balancer or TLS termination services
- The certificate is a very oddball ECDSA-SHA384 type certificate which
has higher CPU cost than a more regular certificate, which has real
effects on our infrastructure
Using normal TLS certificates here improves these things.
I expect there will be some very few devices out there for which this
doesn't work. For the foreseeable future they can simply change the
config to use the old URLs and parameters -- it'll be years before we
can retire those entirely.
For the upgrade client this simply seems like better hygiene. While our
releases are signed anyway, protecting the metadata exchange is _better_
and, again, I doubt many clients will fail this today.
The test is quite odd and specific, but it does reproduce the issue that
caused #9677, so I'd propose to add it to have a simple regression test
for the basic scenario. Also the option to the fakefs might come handy
for other scenarios where you want to quickly test some behaviour on a
filesystem without nanosecond precision, without actually needing access
to one.

(ref #8084)
The current code does not work, because it uses a string in the
replace() method instead of regex. Thus, change it to a proper regex.

The preference for languages in the Accept-Language header field
should not be deduced from the listed order, but from the passed
"quality values", according to the HTTP specification:
https://httpwg.org/specs/rfc9110.html#field.accept-language
This implements the parsing of q=values and ordering within the API
backend, to not complicate things further in the GUI code. Entries
with invalid (unparseable) quality values are discarded completely.
* gui: Fix API endpoint in comment.
gui: Fix incorrect UI language auto detection (fixes#9668)
Currently, the code only checks whether the detected language partially
matches one of the available languages. This means that if the detected
language is "fi" but among the available languages there is only "fil"
and no "fi", then it will match "fi" with "fil", even though the two are
completely different languages.
With this change, the matching is only done when there is a hyphen in
the language code, e.g. "en" will match with "en-US".

This adds a header with the operating system version, verbatim in
whatever format the operating system reports it, to the upgrade check.
The intention is that the upgrade server can use this information to
filter out (or maybe just mark) potentially unsupported upgrades.

### Purpose
Wrap access to Model for users that use the syncthing Go package. See
discussion:
https://github.com/syncthing/syncthing/pull/9619#pullrequestreview-2212484910
### Testing
It works with the iOS app. Other than that, there are no current users
of this API (to my knowledge) as Model was only exposed recently form
the iOS app.
### Purpose
This PR contains the set of changes needed to make Syncthing work on iOS
for [my iOS app for
Syncthing](https://github.com/pixelspark/sushitrain).
Most changes originate from [the Mobius Sync
fork](http://github.com/MobiusSync/syncthing/tree/ios). I have removed
the changes from their fork that are not strictly needed for my app
(i.e. their changes to the GUI and command line utilities, for instance)
and squashed it all in a single commit.
In summary, the changes are:
* Resolve non-absolute paths to the 'Documents' folder (basically the
only one an app can/should write user data to by default on iOS)
* Tweaking of build flags/conditions for iOS (i.e. determine which
basicfs_watch, ignoreresult variant to build for iOS)
* Disable upgrade mechanism on iOS
* Make `RequestGlobal` and `PullerProgress` public symbols
* Expose syncthing.app's Model instance (app.M)
* Add no-op stub for SetLowPriority on iOS
I would very much appreciate these changes to be (eventually) merged to
mainline syncthing, as this would allow my iOS app to track the mainline
source code directly and removes the need (for me at least) for
maintaining a separate fork. Perhaps the Mobius folks can also benefit
from this (although as noted this branch does not contain their changes
to e.g. the GUI).
### Testing
This branch has been tested with the iOS app and appears to work fine.
The full set of MobiusSync changes has been used before with success.
### Screenshots
n/a
### Documentation
There should be no visible changes for users due to this set of changes.
