Tim-Philipp Müller 0c4a702e82 qtdemux: add unit test for edit list regression 
File is the mp4 file from #2549 with the mdat atom
zeroed out and compressed. We compress twice because
apparently compressing 5MB of zeroes effectively in
one run is too difficult for gzip.

/* The goal of this test is to check that qtdemux can properly handle

* This test is simulating DASH bitrate switching (for both playbin and plabyin3)
* and period-change for playbin3
*
* NOTE: During bitrate switching in DASH, track-id might be changed
* NOTE: stream change with new stream-start to qtdemux is playbin3 specific behaviour,
* because playbin configures new demux per period and existing demux never ever get
* new stream-start again.
*
* Testing step
* [GROUP 1]
* - Push events stream-start and segment to qtdemux
* - Push init and media data to qtdemux
* [GROUP 2]
* - Push different (track-id change) init and media data to qtdemux
* without new downstream sticky events to qtdemux
* [GROUP 3]
* - Push events stream-start and segment to qtdemux again
* - Push the init and media data which are the same as GROUP 2
* [GROUP 4]
* - Push events stream-start and segment to qtdemux again
* - Push different (track-id change) init and media data to qtdemux
*
* Expected behaviour
* - Demux exposes srcpad four times, per test GROUP, regardless of track-id change
* - Whenever exposing new pads, downstream sticky events should be detected
* at demux srcpad
