Aside from EOS logic, which is now handled entirely on the client side,
wg_parser_stream_get_event() now only waits for data processing—that is,
demuxing, decoding, and format conversion. While unblocking waits in
wg_parser_stream_get_event() does allow that function to return immediately, a
subsequent seek request in GStreamer will still have to wait for that data
processing to complete and for the stream thread to return to the demuxer's main
loop. In essence, wg_parser_begin_flush() is only moving costs around.
In theory we could force the GStreamer pipeline to complete faster by actually
flushing it. In practice this isn't really true. Individual elements do check
whether they are flushing before processing, but even elements which take a
relatively long time (i.e. multiple milliseconds) to process data don't
periodically check whether they are flushing while doing so. Although there is
arguably a benefit to skipping some elements by flushing the GStreamer pipeline,
it does not seem worth the added code complexity in Wine.
The real point of flushing in DirectShow or GStreamer is to unblock long or
unbounded waits in sink elements (i.e. waits for PTS, or waits for running state
while rendering preroll frames). None of these waits apply here. Waits for
actual sample processing complete in bounded time, and should ideally take less
than the sample DTS to complete (or we are already in trouble).

Currently, the winegstreamer media source checks for EOS when
RequestSample() is called, but doesn't handle the cases when EOS
is detected between the RequestSample() call and the moment when
the request is popped from the command queue and serviced. This
can result in the media source waiting forever for a sample and
get stuck.
This commit fixes the bug by adding a check for EOS in
wait_for_event().

For asynchronous elements like a media source the paused state is rather
similar to the playing state. The most revelant difference is that
RequestSample commands are not immediately executed, but are scheduled
in an internal queue. As soon as playback is restarted, all pending
operations are submitted again (or they are discarded if playback is
stopped).
This patch implements such a queue, together with proper event emitting
when the media source is paused. Also, the characteristic
MFMEDIASOURCE_CAN_PAUSE is announced.
This patch is required for correct playback of some videos in Deep Rock
Galactic.

When starting a media source, the caller can specify a timestamp to seek
to by mean of a PROPVARIANT argument. If the PROPVARIANT is empty, then
no seek operation has to take place: playback has to either restart from
the beginning (if the media source was previously in stopped state) or
from where it was left (if the media source was in paused state).
Also, when a PROPVARIANT is empty it is a bug to use its content, because
there is no guarantee that it is initialized to a sensible value.
This patch fixes both bugs by gating the seek operation with the check
that the PROPVARIANT has the right type.

Currently the media source emit a presentation timestamp relative to
when the playback was last restarted. I.e., the frame that sits two
seconds inside a media file will get timestamp 2 if playback was
started at the beginning of the file, but will get timestamp 1 if
playback was last restarted at second 1.
This does not match Windows behavior, where each frame always gets
the same timestamp independently from where playback was started.

This necessitates an extra blit for the input data, but this is necessary for
both WoW64 support and an internal rework of the source path in wg_parser to use
GstAppSrc. Since source data is usually compressed and not a bottleneck, we
don't expect this to affect performance.

Instead of having mixing together IMFMediaSource::Shutdown() and the
constructors' failure paths, creating confusion about what should be released
where, designate ::Shutdown/::Release to shutting down fully initialized objects
without checks, and keep the partially-created object cleanup code in the
constructor.
