mfreadwrite/tests: Test source reader transforms with MF_SOURCE_READER_ENABLE_ADVANCED_VIDEO_PROCESSING.

I missed that a few of these had the defwinproc flag when
initially adding them.

Current implementation handles correctly % only at the end of the
string. Nothing else matches.

The new implementation while naïve and recursive handles both _ and *
correctly.

When playing a loop, and if no end of loop point has been defined
(meaning = play whole segment), don't rely on segment's length for
wave tracks as their length is always 1.  Compute segment length in
this case by grabbing each track's playback length in segment state's
internal graph.  This feature is only activated for messages generated
by wave tracks, but could be extended if needed to other types of
messages.

Store track_flags inside segment state so that they can be reused in
subsequent calls.  The start/seek/loop flags are now properly set when
calling IDirectMusicTrack_Play().

It's possible that a state object pointer not in the topology node collection gets passed to
session_get_node_object(). Instead of returning the last node when the object is not found, we
should return a NULL so that the state of the last node is not changed by mistake.

Doing so triggers a permissions prompt for input monitoring.
