Some filesystems don't have meaningful access times under at least some
circumstances (see #2189, #2205). In this situation the traditional stat()
and related kernel interfaces have to put something meaningless in the
st_atime field, and have no way to signal that it is meaningless.
However, statx() does have a way to signal that the atime is meaningless:
if the filesystem doesn't provide a useful access time, it will unset
the STATX_ATIME bit (as well as filling in the same meaningless value
for the stx_atime field that stat() would have used, for compatibility).
We don't actually *need* the atime, so never include it in the required
mask. This was already done for one code path in commit 6fc143bb
"gio: Allow no atime from statx" to fix#2189, but other callers were
left unchanged in that commit, and receive the same change here.
It is not actually guaranteed that *any* of the flags in the
returned stx_mask will be set (the only guarantee is that items in
STATX_BASIC_STATS have at least a harmless compatibility value, even if
their corresponding flag is cleared), so it might be better to follow
this up by removing the concept of the required mask entirely. However,
as of Linux 5.8 it looks as though STATX_ATIME is the only flag in
STATX_BASIC_STATS that might be cleared in practice, so this simpler
change fixes the immediate regression.

It is not allowed to be `NULL` or unset if requested by the file
attribute matcher. Derive it from the basename. This doesn’t handle the
situation of a failed UTF-16 to UTF-8 conversion very well, but will at
least return something.
Note that the `g_filename_display_basename()` function can’t be used as
`GWinHttpFile` provides its URI in UTF-16 rather than in the file system
encoding.
This fixes a crash when using GIMP on Windows. Thanks to lillolollo for
in-depth debugging assistance.

This isn’t used in the build at all, it’s just a copy of the model file
which is uploaded in our Coverity configuration. This should be kept up
to date with changes in the file on the Coverity servers.

`uri` is always non-`NULL` by the time the `fail` label is reached, so
drop the `NULL` pointer check. Inline the `fail` code since it’s only
used from two places.

For interoperability with libdbus, we want to use compatible timeouts.
In particular, this fixes a spurious failure of the `gdbus-server-auth`
test caused by libdbus and gdbus choosing to expire the key (cookie) at
different times, as diagnosed by Thiago Macieira. Previously, the libdbus
client would decline to use keys older than 7 minutes, but the GDBus
server would not generate a new key until the old key was 10 minutes old.
For completeness, also adjust the other arbitrary timeouts in the
DBUS_COOKIE_SHA1 mechanism to be the same as in libdbus. To make it
easier to align with libdbus, create internal macros with the same names
and values used in dbus-keyring.c.
* maximum time a key can be in the future due to clock skew between
systems sharing a home directory
- spec says "a reasonable time in the future"
- was 1 day
- now 5 minutes
- MAX_TIME_TRAVEL_SECONDS
* time to generate a new key if the newest is older
- spec says "If no recent keys remain, the server may generate a new
key", but that isn't practical, because in reality we need a grace
period during which an old key will not be used for new authentication
attempts but old authentication attempts can continue (in practice both
libdbus and GDBus implemented this logic)
- was 10 minutes
- now 5 minutes
- NEW_KEY_TIMEOUT_SECONDS
* time to discard old keys
- spec says "the timeout can be fairly short"
- was 15 minutes
- now 7 minutes
- EXPIRE_KEYS_TIMEOUT_SECONDS
* time allowed for a client using an old key to authenticate, before
that key gets deleted
- was at least 5 minutes
- now at least 2 minutes
- at least (EXPIRE_KEYS_TIMEOUT_SECONDS - NEW_KEY_TIMEOUT_SECONDS)

If one thread pool thread fails to set its scheduler settings, it’s
likely that all the rest of them will fail for the same reason. Avoid
printing duplicate critical warnings in that case.

If the calling code adds more option entries than `G_MAXSIZE` then
there’ll be an integer overflow. This seems vanishingly unlikely (given
that all callers use static option entry lists), but add a precondition
anyway.
