lib/fs: Clarify errors for Windows filenames (fixes #8968) (#8969)
With this change, error messages include the offending characters or
name parts. Examples:

    nul.txt: name is invalid, contains Windows reserved name: "nul"
    foo>bar.txt: name is invalid, contains Windows reserved character: ">"
    foo \bar.txt: name is invalid, must not end in space or period on Windows

lib/config, gui: Disallow some options in combination with "untrusted" (fixes #8920) (#8921)
This prevents combining untrusted with introducer and auto-accept, and
also verifies that folders shared with untrusted devices have passwords
at config loading time.

Don't add empty device to config on init (#8933)
We usually want to ensure that our own device is present. However if the
given device ID is the empty ID, we shouldn't do that. This is a
legimate (though way too non-obvious) use-case when opening the config
without knowing/caring about the device ID.

lib/model: Set platform data for new folders w/ ignorePerms (ref #8883) (#8907)
* Platform data (ownership, xattrs, etc.) is now set correctly for newly-received folders, even if the received folder has the NoPermissions flag.

* Call setPlatformData on receivers that have ignorePerms set to true.

1103a27337 all: Grand test refactor (fixes #8779, fixes #8799)
This fixes various test issues with Go 1.20.

- Most tests rewritten to use fakefs where possible
- Some tests that were already skipped, or dubious (invasive,
  unmaintainable, unclear what they even tested) have been removed
- Some actual code rewritten to better support testing in fakefs

lib/ignore: Properly handle non-existing included ignore-files (fixes #8764) (#8874)
In the sequence of loading ignores, the error File Does Not Exist is not being considered a fatal  error, since the .stignore file is allowed to not exist. However, included ignore files also tossed that same error in case those do not exist while in those cases it's considered an error and it should lead to the folder stopping. Changing the error when opening an included ignore file to something other than the regular does fix this issue, as in it now works again as described in the Documentation.

09efe03e1d lib/connections: Avoid using nil lanChecker

lib/config, lib/connections: Configurable protocol priority (ref #8626) (#8868)
This makes the various protocol priorities configurable among the other
options. With this, it's possible to prefer QUIC over TCP for WAN
connections, for example. Both sides need to be similarly configured for
this to work properly.

The default priority order remains the same as previously (TCP, QUIC,
Relay, with LAN better than WAN).

To make this happen I made each dialer & listener more priority aware,
and moved the check for whether a connection is LAN or not into the
dialer / listener -- this is the new "lanChecker" type that's passed
around.

lib/model: Set enc. trailer size on pull (ref #8563, #8556) (#8839)
In the original fix in #8563 I simply forgot this. Which meant #8556
wasn't actually fixed, as the trialer size would have been 0 (default),
and thus we would have still sent the inflated size to encrypted peers.

lib/model: Fix file size inconsistency due to enc. trailer (#8840)
lib/model: Fix file size inconsisency due to enc. trailer

Fixes a regression due to PR #8563, while arguable the bug was actually
introduced in a much older PR #7155, but didn't have any bad effects so
far:
We account for the encryption trailer in the db updater routine,
calculating the file-info size there. However there's no guarantee that
the file-info at this point is still the exact same as when it was
written. It was before, but isn't anymore since introducing the new
EncryptedTrailerSize field.
Fix: Adjust the size in the info at the same place where the trailer is
written, i.e. we definitely have the actual size on disk.

lib/config: Allow sub-second watcher delay (fixes #7859) (#7864)
Allow the watcher delay to take fractional values, effectively allowing
for much shorter delays. The minimum value is limited at 0.01, which
effectively translates to 10ms. This is required in order to guarantee
that there is still enough time to aggregate multiple single change
events.

leaving it as an opaque base64 string because no meaning should be
derived from it: it's just a string.

Handle relay connect timeout (fixes #8749) (#8755)
This makes sure the service manager doesn't interpret timeout errors, or any other error, as a signal to stop the service instead of restarting it.

I added it directly to our service utility function, as it may help catch other instances of the same problem... We would typically want timeouts etc to be a retryable error, unless it is the top level context that has timed out and we check for that specifically.

gui, api: Indicate running under container (#8728)
This adds a word to the version string when running containerized. The
purpose is mostly to facilitate troubleshooting via screenshot by
"leaking" this rather important aspect of the setup. Additionally, the
version row gets "no-overflow-ellipsis" treatment so that the whole
thing is actually visible in the GUI and the (now useless) tooltip is
removed. In production releases this won't make a difference as the
whole thing will typically fit, but in odd setups it provides more info
up front.

gui, lib/connections: Let the backend decide whether connection is local (fixes #8686) (#8694)
* lib/connections: Cache isLAN decision for later external access.

The check whether a remote device's address is on a local network
currently happens when handling the Hello message, to configure the
limiters.  Save the result to the ConnectionInfo and pass it out as
part of the model's ConnectionInfo struct in ConnectionStats().

* gui: Use provided connection attribute to distinguish LAN / WAN.

Replace the dumb IP address check which didn't catch common cases and
actually could contradict what the backend decided.  That could have
been confusing if the GUI says WAN, but the limiter is not actually
applied because the backend thinks it's a LAN.

Add strings for QUIC and relay connections to also differentiate
between LAN and WAN.

* gui: Redefine reception level icons for all connection types.

Move the mapping to the JS code, as it is much easier to handle
multiple switch cases by fall-through there.

QUIC is regarded no less than TCP anymore.  LAN and WAN make the
difference between levels 4 / 3 and 2 / 1:

{TCP,QUIC} LAN --> {TCP,QUIC} WAN --> Relay LAN --> Relay WAN -->
Disconnected.
