hlsdemux: tests: add unit tests for hlsdemux

Using the new GstAdaptiveDemux test framework, add tests that exercise hlsdemux. The following tests are added: simpleTest A simple playlist that contains some media URLs testMediaPlaylist A master playlist with a variant playlist that contains media URLs testMediaPlaylistNotFound A master playlist that points to a missing variant playlist testFragmentNotFound A master playlist with a variant playlist that contains media URLs There is a missing media file referenced from the variant playlist. testFragmentDownloadError A master playlist with a variant playlist that contains media URLs During the download of one media file, the test simulates the network connection being dropped. testSeek A simple test of trying to perform a seek on an HLS stream.
