Just to make it a little more obvious that a thread pool can be
initialised with one thread per logical CPU.

It may be defined by the environment (we document that as being allowed)
— if so, individual files should not try to redefine it, as that causes
a preprocessor warning.

Apparently, the function calls added in 11729cdc use Foundation, not
Cocoa. Cocoa is a massive superset of Foundation, and is not available
on iOS.
Patch contributed by Jay Freeman, but without providing an e-mail
address. So the git commit cannot be attributed to him.

Fixes: #1869
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.
Signed-off-by: Philip Withnall <withnall@endlessm.com>
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:

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

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().
