The `make_pollfd()` call can’t fail because it only does so if
`cancellable == NULL`, and we’ve already checked that. Assert that’s the
case, to shut Coverity up and to catch behavioural changes in future.

`g_strsplit()` never returns `NULL`, although it can return an empty
strv (i.e. with its first element being `NULL`).
Drop a redundant `NULL` check.

Otherwise it could possibly overflow on 32-bit machines if `year` is
high enough, although I don’t think that’s possible because of limits
applied on it by callers. This should shut Coverity up though.
The limits applied by callers could be circumvented by calling (say)
`g_date_time_add_years()` multiple times. That’s a bug, but not one I’m
going to fix today.

This might eliminate some false positives being thrown by Coverity to
do with the return value of `uri_decoder()` and whether it’s allocated
anything.

If `statx()` is supported, query it for the file creation time and use
that if returned.

This currently just implements the same functionality as the existing
`stat()`/`fstat()`/`fstatat()`/`lstat()` calls, although where a reduced
field set is requested it may return faster.

It turns out that our async write operation implementation is broken
on non-O_NONBLOCK pipes, because the default async write
implementation calls write() after poll() said there were some
space. However, the semantics of pipes is that unless O_NONBLOCK is set
then the write *will* block if the passed in write count is larger than
the available space.
This caused a deadlock in https://gitlab.gnome.org/GNOME/glib/-/issues/2182
due to the loop-back of the app stdout to the parent, but even without such
a deadlock it is a problem that we may block the mainloop at all.
In the particular case of g_subprocess_communicate() we have full
control of the pipes after starting the app, so it is safe to enable
O_NONBLOCK (i.e. we can ensure all the code using the fd after this can handle
non-blocking mode).
This fixes https://gitlab.gnome.org/GNOME/glib/-/issues/2182
This has almost the same semantics as WSAECONNRESET and for all
practical purposes is handled the same. The main difference is about
*who* reset the connection: the peer or something in the network.
For UDP sockets this happens when receiving packets and previously sent
packets returned an ICMP "Time(-to-live) expired" message. This is
similar to WSAECONNRESET, which on UDP sockets happens when receiving
packets and previously sent packets returned an ICMP "Port Unreachable"
message.
This is a step towards supporting `statx()`, which allows the set of
fields it returns to be specified by the caller. Currently, the existing
`stat()` and `fstat()` calls continue to be made, and there are no
behavioural changes — but the new wrapper functions will be extended in
future.

Don’t call `g_file_query_exists()` followed by `g_file_delete()`. Just
call `g_file_delete()` and check the error.
