    appsrc: Always take the mutex before flushing the queue

    Otherwise the application might push new buffers into the queue while we're
    flushing, potentially causing the GQueue data structure to become
inconsistent
    and causing crashes soon after.

    appsrc: retain the latest caps in queue when flushing

    - Retain the latest caps in the internal queue, when
      flushing.
    - Add a unit test case for the same.
