[PATCH v2 0/4] MR5917: Misc. winegstreamer fixes

[Torge Matthies (＠tmatthies)]

Mostly race condition fixes.

"winegstreamer: Do waits for samples on stream-specific work queues." works around a Gstreamer bug that I'll try to write a minimal reproducer for and submit to their bug tracker. For now, doing sample waits actually concurrently works around the problem.

"winegstreamer: Fixate caps in autoplug_continue_cb." so far I've only seen relevant when the source is a uridecodebin (in Proton), but I though it couldn't hurt to upstream it too.

--
  v2: winegstreamer: Handle Gstreamer pipeline flushes gracefully in the media source.
      winegstreamer: Ignore an assert in wg_parser.
      winegstreamer: Don't only accept segment events when streams are enabled.
