port to 0.11 patch

Besides updating to use the new API's I have made a few changes to make it
work.

GstFragment:
 * Changed buffer list to plain buffer .
 * Added a caps property with type find functionality.
 * Removed unused headers functionality.

GstHLSDemux:
 * Changed processing queue to use GstFragment's instead of buffer lists.
 * Removed comment + code which says it shouldn't be required in 0.11
(untested).
 * Adapted to GstFragment returning buffers instead of buffer lists.
 * Fixed potential leak in gst_hls_src_buf_to_utf8_playlist().
 * Fixed leaking caps after type switching.

GstURIDownloader:
 * Fixed incorrect use of gst_pad_activate_mode() (was
gst_pad_activate_push()).
 * Added missing gst_pad_event_default() to gst_uri_downloader_sink_event().

Since there is no compatible MPEG-TS demuxer I have only tested it using
filesink and fakesink.
Example: gst-launch-1.0 souphttpsrc
location=http://devimages.apple.com/iphone/samples/bipbop/gear4/prog_index.m3u8
! hlsdemux ! fakesink sync=true -v
