Various different BSD systems use a different errno from `E_LOOP` (as
defined by POSIX and used on Linux) to indicate that a file is a symlink
when you try to `open()` it with `O_NOFOLLOW`.
Fix the code which detects this. This is a follow-up to #1302.

Add some basic DAG attributes so that some jobs in the pipeline can
run out of stage order to speed things up a little.

These jobs (`scan-build` and `valgrind`) take ages to run and rarely
indicate failures, so move them to a weekly schedule, rather than
running them on each branch/MR.
The current schedule is once weekly:

These exercise all the code paths I can manage without adding a load of
machinery to inject faults into `write()`.

Where applicable. Where the current use of `g_file_set_contents()` seems
the most appropriate, leave that in place.

This is used when creating the temporary file, or new file from scratch.
I wondered about also allowing the file owner and group to be set, but
that’s not as generally applicable — if your process is operating across
multiple user IDs then it likely has some fairly OS-specific
requirements and will need tighter control of its syscalls anyway.
(Eventually, support for setting the file owner and group atomically
could be added by writing out a file using `O_TMPFILE` so it’s not
addressable, and then linking it into the file system in place of the
old file using something like `renameat2(AT_EMPTY_PATH)` or `linkat()`.
That’s currently not possible without patching the kernel with
https://marc.info/?l=linux-fsdevel&m=152472898003523&w=2, as far as I
know at the moment.)

Fixes: #1203
This moves `write_to_temp_file()` into `g_file_set_contents_full()` and
coalesces its handling of `do_fsync` with the `rename_file()` call. It
adds support for `G_FILE_SET_CONTENTS_DURABLE` and
`G_FILE_SET_CONTENTS_NONE` — previously only
`G_FILE_SET_CONTENTS_CONSISTENT | G_FILE_SET_CONTENTS_ONLY_EXISTING` was
supported.
In the case that `G_FILE_SET_CONTENTS_CONSISTENT |
G_FILE_SET_CONTENTS_DURABLE` is set, an additional `fsync()` is now done
on the directory after renaming the temporary file.
In the case that `G_FILE_SET_CONTENTS_ONLY_EXISTING` isn’t set, the
`fsync()` after writing the temporary file will always be done (unless
the file system guarantees it never needs to be done).
In the case that only `G_FILE_SET_CONTENTS_DURABLE` is set, the
destination file will be written to directly (using this mode is not
really advised).

This introduces no functional changes, just makes the code a bit more
modular and reusable.

This is a new version of the g_file_set_contents() API which will allow
its safety to be controlled by some flags, allowing the user to choose
their preferred tradeoff between safety (`fsync()` calls) and speed.
Currently, the flags do nothing and the new API behaves like the old
API. This will change in the following commits.

The previous implementation of g_uri_unescape_segment() allowed non-utf8
decoded characters. uri_decoder() allows it too with FLAGS_ENCODED (I
think it's abusing a bit the user-facing flags for some internal
decoding behaviour)
However, it didn't allow \0 in the decoded string. Let's have an extra
check for that, outside of uri_decoder().

Give GAppInfo a bunch of readonly properties, and
support them in GDesktopAppInfo. This makes app infos
more convenient to work with in GTK4, and in general.
Rather than fetching the entire repository history, limit the fetch
depth to commits in the last 4 weeks. If a branch was branched longer
than 4 weeks ago, it seems reasonable to require it to be rebased before
it can be reviewed.
At the current rate of development, this reduces the bandwidth needed
for git pulls in the initial code checks from 73MB to 9MB.

`getenv()` doesn't work well on Windows, f.ex., it can't fetch env
vars set with `SetEnvironmentVariable()`. This also means that it
doesn't work at all when targeting UWP since that's the only way to
set env vars in that case.
This adds really basic validation that `GTimeZone` can successfully
parse a ‘slim’ format timezone file.
