"Uninitialized value" is partially correct, since it has not been
initialized with a type, but it's more precise to say
"zero-initialized value". It is still a programming error to pass a
pointer to uninitialized memory with arbitrary contents as the value.

This comment was correct until commit adf1f98f62, when the `GTimeVal`
which the result was put into (introducing the Y2038-unsafety) was
dropped.
The adjustment and scaling of the `FILETIME` should not make it
Y2038-unsafe: the maximum `FILETIME` is 2^64-1. Subtracting the epoch
adjustment and dividing by 10 gives the timestamp 1833029933770955161,
which is in June 58086408216 (at just after 3am UTC). I think that’s
enough time to be going on with.

This requires some reworking of the internal g_date_time_new_from_unix()
function, since it previously operated in seconds, which wasn’t high
enough resolution — the g_get_current_time() code path used to operate
in microseconds.

They use the deprecated GTimeVal type, which is not year 2038 safe, so
have to be deprecated.

These are alternatives to g_file_info_{get,set}_modification_time(),
which will soon be deprecated due to using the deprecated GTimeVal
type, which is not year 2038 safe.
The new APIs take a GDateTime instead.

The former is now deprecated, so it makes sense to base its
implementation on the latter, rather than the other way around.
This introduces no functional changes.

GTimeVal is subject to the year 2038 problem, since its `tv_sec` field
is a `glong`, which is 32 bits on 32-bit platforms.
Use `guint64` to represent microsecond-precision time since the Unix
epoch; or use `GDateTime` for full date/time representation.

It’s not Y2038-safe, as it’s 32-bit. While it was previously deprecated
in the documentation, now add the deprecation annotation for the
compiler.

This is a simple wrapper around g_date_time_format_iso8601() which
always produces ISO 8601 dates, without people having to remember the
format string for them (and with the convenience of terminating UTC
dates with ‘Z’ rather than ‘+00’).

The event source used to handle inactivity_timeout doesn't hold a
reference on the application. Therefore, it is possible for callback
function of the event source to run after the application has been
freed, leading to use-after-free problem. To avoid the problem, we
should remove the event source before the application is freed.
This should fix SIGBUS crash of gio/tests/gapplication on FreeBSD.

Try to create the complete path right away and fall back
to creating all path elements one by one.
This also helps to avoid TOCTTOU problems and avoids walking
the path all the time, providing a nice performance gain, by
avoiding syscalls.
Ignore ENOENT errors up until the last element while trying to create each
of the path elements in case a restricted file-system is being used where
path elements can be hidden or non-accessible.
