The gst_h264_parse_pps() function dynamically allocates the slice
group ids map array, so that needs to be cleared before parsing a
new PPS NAL unit again, or when it is no longer needed.
Likewise, a clean copy to the internal NAL parser state needs to be
performed so that to avoid a double-free corruption.

The recovery point SEI message helps a decoder in determining if the
decoding process would produce acceptable pictures for display after
the decoder initiates random access or after the encoder indicates
a broken link in the coded video sequence.
This is not used in the h264parse element, but it could help debugging.

Add nal_reader_skip_long() helper function to allow an arbitrary number
of bits to be skipped. The former nal_reader_skip() function is too
limited to the actual cache size.
Use this new function to simplify gst_h264_parser_parse_sei_message()
default case, that skips unsupported payloads.
v2: made args consistent from header to source file.

Use the first _gst_reserved[] slot to hold the built-in range decoder
private data. The first slot was formerly the buffer size, which was
then promoted to semi-public namespace when it got integrated as git
commit 2940ac6.

It was previously a mix and match of both variants, introducing just too much
confusion.
The prefix are from now on:
* GstMpegts for structures and type names (and not GstMpegTs)
* gst_mpegts_ for functions (and not gst_mpeg_ts_)
* GST_MPEGTS_ for enums/flags (and not GST_MPEG_TS_)
* GST_TYPE_MPEGTS_ for types (and not GST_TYPE_MPEG_TS_)
The rationale for chosing that is:
* the namespace is shorter/direct (it's mpegts, not mpeg_ts nor mpeg-ts)
* the namespace is one word under Gst
* it's shorter (yah)
Allows automatic negotiation of the size in the following case:
gst-launch-1.0 glvideomixer name=m sink_0::xpos=0 sink_1::xpos=320 ! glimagesink \
videotestsrc ! m. \
videotestsrc pattern=1 ! m.

This is too allow gst-launch debugging with multiple GL contexts as
well as avoiding segfaulting innocent gtk+ apps that have not called
XInitThreads.

We cannot do it as the winsys may crash if we initialize too late.
Example, GLX contexts with Intel drivers:
Intel requires the X Display to be the same in order to share GL
resources across GL contexts. These GL contexts are generally
accessed from different threads. Without winsys support it is
nearly impossible to guarentee that concurrent access will not
occur. This concurrent access could result in crashes or abortion
by the winsys (xcb).
