buffer: rework flags a little

Browse source 
Reorder buffer flags and add some new ones.
Remove the media specific flags, we can now easily do this with the FLAG_LAST
flag because we don't extend from GstBuffer anymore.

* GstBufferFlags:
* @GST_BUFFER_FLAG_LIVE: the buffer is live data and should be discarded in
* the PAUSED state.
* @GST_BUFFER_FLAG_DISCONT: the buffer marks a discontinuity in the stream.
* This typically occurs after a seek or a dropped buffer
* from a live or network source.
* @GST_BUFFER_FLAG_IN_CAPS: the buffer has been added as a field in a #GstCaps.
* @GST_BUFFER_FLAG_GAP: the buffer has been created to fill a gap in the
* stream and contains media neutral data (elements can
* switch to optimized code path that ignores the buffer
* content).
* @GST_BUFFER_FLAG_LIVE: the buffer is live data and should be discarded in
* the PAUSED state.
* @GST_BUFFER_FLAG_DISCONT: the buffer marks a data discontinuity in the stream.
* This typically occurs after a seek or a dropped buffer
* from a live or network source.
* @GST_BUFFER_FLAG_RESYNC: the buffer timestamp might have a discontinuity
* and this buffer is a good point to resynchronize.
* @GST_BUFFER_FLAG_CORRUPTED: the buffer data is corrupted
* @GST_BUFFER_FLAG_MARKER: the buffer contains a media specific marker. for
* video this is typically the end of a frame boundary, for audio
* this is usually the end of a talkspurt.
* @GST_BUFFER_FLAG_HEADER: the buffer contains header information that is
* needed to decode the following data
* @GST_BUFFER_FLAG_GAP: the buffer has been created to fill a gap in the
* stream and contains media neutral data (elements can
* switch to optimized code path that ignores the buffer
* content).
* @GST_BUFFER_FLAG_DELTA_UNIT: this unit cannot be decoded independently.
* @GST_BUFFER_FLAG_MEDIA1: a flag whose use is specific to the caps of the buffer. Since: 0.10.23.
* @GST_BUFFER_FLAG_MEDIA2: a flag whose use is specific to the caps of the buffer. Since: 0.10.23.
* @GST_BUFFER_FLAG_MEDIA3: a flag whose use is specific to the caps of the buffer. Since: 0.10.23.
* @GST_BUFFER_FLAG_MEDIA4: a flag whose use is specific to the caps of the buffer. Since: 0.10.33.
* @GST_BUFFER_FLAG_LAST: additional flags can be added starting from this flag.
* @GST_BUFFER_FLAG_IN_CAPS: the buffer has been added as a field in a #GstCaps.
*
* @GST_BUFFER_FLAG_LAST: additional media specific flags can be added starting from
* this flag.
*
* A set of buffer flags used to describe properties of a #GstBuffer.
