### 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

### Documentation
There should be no visible changes for users due to this set of changes.

Tiny cleanup I noticed while trying to fix/test another issue
(https://github.com/syncthing/syncthing/pull/9600). I shortly tried to
figure out what it was used for in the past, but gave up without
results.
Previously we queried cache with backslashes, and stored entries with
slashes. As in no cache hits ever for non-toplevel files. I also
eventually remembered that cache is disabled by default, so this is a
bit pointless, but still right :P
### Purpose
Avoid the issue where the folder marker is deleted by overzealous
cleanup tools because it's just a useless, empty directory.
We create a small file containing a an admonishment to not delete the
directory, and some metadata that is just for human consumption at the
moment. (But it would parse as a valid yaml file if we wanted to read
this, at some point.)
This will only apply when _creating_ a folder marker, that is, existing
setups will not gain the file automatically. Obviously, when using a
custom folder marker none of this applies.
Also, slightly adjust the permission bits for the folder marker directory and file on Unixes, making sure the group & write bits are unset.
### Testing
I've created and deleted a few folders and it appears to behave as I
expect.

Currently the maximum delay is always derived automatically from the
initial delay. This is fine in most cases, but for some use cases (large
files that take a long time to write) we need to be able to set a longer
max delay than the computed value (e.g., 15s delay with 10min timeout).
This adds a small package `geoip` which knows how to download and manage
the Maxmind GeoLite2 database we use. This removes the need for various
scripts to download and manage the geoip database, something that today
happens on Docker startup for the relay pool server and using various
hand written hacks for the usage reporting server.
The database is downloaded when needed and then refreshed on a
best-effort basis weekly.
### Purpose
Adds a new metric `syncthing_connections_active` which equals to the
amount of active connections per device.
Fixes#9527
<!--
Describe the purpose of this change. If there is an existing issue that
is
resolved by this pull request, ensure that the commit subject is on the
form
`Some short description (fixes#1234)` where 1234 is the issue number.
-->
### Testing
I've manually tested it by running syncthing with these changes locally
and examining the returned metrics from `/metrics`.
I've done the following things:
- Connect & disconnect a device
- Increase & decrease the number of connections and verify that the
value of the metric matches with the amount displayed in the GUI.
### Documentation
https://github.com/syncthing/docs/blob/main/includes/metrics-list.rst
needs to be regenerated with
[find-metrics.go](https://github.com/syncthing/docs/blob/main/_script/find-metrics/find-metrics.go)

### Purpose
Firefox uses the last specified favicon link for bookmarks, but only if
it is available on initial page load.
Remove the second link and use ng-href to change the icon instead.
I'm not really familiar with AngularJS, feel free to offer suggestions
for improvements.
### Testing
Briefly tested on Firefox 124.0.2 and Chrome 123.0.6312.105.
### Purpose
Resend our indexes since we fixed that index-sending issue.
I made a new thing to only drop the non-local-device index IDs, i.e.,
those for other devices. This means we will see a mismatch and resend
all indexes, but they will not. This is somewhat cleaner as it avoids
resending everything twice when two devices are upgraded, and in any
case, we have no reason to force a resend of incoming indexes here.
### Testing
It happens on my computer...
The commit 7e4e65ebf5 added links to
devices listed in the Shared With list in the folder info. However, it
only added them to those that had no superscript next to them.
With this change, the links are added to all devices regardless of
whether they have the superscript next to their names or not. The commit
also simplifies the code by using anchors directly instead of wrapping
them in spans.
