Following on from #2907, set various boolean attributes if they have
been requested, or are known for sure, and their value is `FALSE`.
Previously the `FALSE` value would have been implicitly returned by the
getter function, but now doing that without the attribute being
explicitly set will trigger a critical warning.
*Don’t* set these attributes if their value is unknown or there was an
error querying it.

The `is-backup` attribute isn't currently set on Windows. It would
be nice to set such basic attributes on all platforms. Let's set
the attribute to `FALSE` there.
Currently, the `G_FILE_ATTRIBUTE_STANDARD_IS_BACKUP` attribute is set
only when its value is `TRUE`. This is wrong with the latest changes as
the `GLib-GIO-CRITICAL **: 00:54:07.260: GFileInfo created without
standard::is-backup` errors are printed now from the
`g_file_info_get_is_backup` function among others. Let's set this
aattribute also when it is `FALSE`.

The lost+found dir isn't detected as hidden currently. This is regression
caused by the commit 728ad64b. Let's change the code a bit to be sure that
the lost+found dir is marked as hidden again.
When the `g_file_copy` function is used with files on BTRFS, the
`GLib-GIO-FATAL-CRITICAL: GFileInfo created without standard::size`
error is printed. This is because the `g_file_get_size` function
is used to obtain the file size for the progress callback, but it uses
the wrong `GFileInfo` object that is meant for attributes to be copied
with the file. The file size attribute is missing there obviously. Let's
obtain the file size over the `fstat` call the same way as it is done in
the `splice_stream_with_progress` function to get rid of those errors
and to fix the progress reporting.
Similar to commit 6e44151bf7, skip the test if gdb is unable to read
/proc/PID/mem, which gdb does as a fallback if ptrace is unavailable.
This allows the test to skip when run under Gentoo's sandbox.
The "emit a critical warning if your object notifies a property during
finalization" entry should have been added in 2.75.1, but better late
than never.

Add a missing steal call in `schedule_method_call()`. This introduces no
functional changes, but documents the ownership transfer more clearly.

This `GDBusMethodInvocation` may be shared across threads, with no
guarantee on the strong ref in one thread outlasting any refs in other
threads — so it needs a ref in this helper struct.
This should fix a use-after-free where the `GDBusMethodInvocation` is
freed from `g_value_unset()` after `g_signal_emit()` returns in
`dispatch_in_thread_func()` in one thread; but then dereferenced again
in `g_source_destroy_internal()` from another thread.

The `GDBusInterfaceSkeleton` is already stored as the source object of
the `GTask` here, with a strong reference.
Storing it again in the task’s data struct is redundant, and makes it
look like the `GDBusInterfaceSkeleton` is being used without holding a
strong reference. (There’s not actually a bug there though: the strong
reference from the `GTask` outlives the data struct, so is sufficient.)
Remove the unnecessary helper struct member to clarify the code a bit.

Otherwise it’s possible for it to hang around in the `GMainContext`
after the “send message” operation has finished. In the best case, this
will cause the `GTask` and `GDBusMessage` to not be freed when the
calling code expects. In the worst case, it could cause use-after-free
problems if it derefs allocations which have since been freed.
I have not seen either of these problems in practice, but it would be
best for the code to eliminate the risk of them altogether by explicitly
destroying the source when the operation is finished.

This introduces no functional changes, but makes it a little clearer how
the ownership of these `GDBusMessage` instances works. The free function
is changed to `g_clear_object()` to avoid the possibility of somehow
using the messages after freeing them.
Basically just some drive-by docs improvements while trying to debug
issue #1264.

This didn’t actually cause any observable bugs, since the structures of
`PropertyData` and `PropertyGetAllData` were equivalent for the members
which the free function touches.
Definitely should be fixed though.

This appears to fix an intermittent failure seen when sending a D-Bus
message with either of a cancellable or a timeout set.
In particular, I can reliably reproduce it with:
```
meson test gdbus-test-codegen-min-required-2-64 --repeat 10000
```
It can be caught easily with asan when reproduced. Tracking down the
location of the refcount mismatch was a little tricky, but was
simplified by replacing a load of `g_object_ref (message)` calls with
`g_dbus_message_copy (message, NULL)` to switch `GDBusMessage` handling
to using copy semantics. This allowed asan to home in on where the
refcount mismatch was happening.
The problem was that `send_message_data_deliver_error()` takes ownership
of the `GTask` passed to it, but the
`send_message_with_replace_cancelled_idle_cb()` and
`send_message_with_reply_timeout_cb()` functions which were calling it,
were not passing in a strong reference as they should have.
Another approach to fixing this would have been to change the transfer
semantics of `send_message_data_deliver_error()` so it was `(transfer
none)` on its `GTask`. That would probably have resulted in cleaner
code, but would have been a lot harder to verify/review the fix, and
easier to inadvertently introduce new bugs.
The fact that the bug was only triggered by the cancellation and timeout
callbacks explains why it was intermittent: these code paths are
typically never hit, but the timeout path may sometimes be hit on a very
slow test run.
