            Bug ID: 244534
           Summary: [GStreamer] MediaPlayerPrivateGStreamer: Abort stale
                    tasks on flushes
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKitGTK
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: aboya at igalia.com
                CC: bugs-noreply at webkitgtk.org

This patch is a combination of a follow-up of
https://github.com/WebKit/WebKit/pull/3746, and a fix for a race
condition I independently discovered before said PR was published.

Minor cleanups for pr/3746 are done, additional logging is added,
MediaPlayerPrivateGStreamer::m_abortableTaskQueue is renamed to
MediaPlayerPrivateGStreamer::m_sinkTaskQueue, comments are added, and
most importantly: the task queue is flushed when a GStreamer flush is
received. This fixes a race condition on MSE flushes.
