Fix build when GST_DISABLE_GST_DEBUG is not defined. Use a switch
statement to dispatch to the various SEI payload handlers.

The payloadSize does not account for emulation prevention bytes. So,
just use nal_reader_skip() for skipping payload_size bits. It should
be possible to further optimize this code since the NAL reader shall
be aligned to byte boundary already.
Kill the now unused nal_reader_skip_to_next_byte() function.

Fix parsing of buffering_period() SEI messages. The number of bits
used to express {nal,vcl}_initial_cpb_removal_delay{,_offset} syntax
elements is not 5 but 1 + initial_cpb_removal_delay_length_minus1.

Account for trailing zero bits when checking for rbsp_more_data().
In particular, fix an hypothetical stream whereby rbsp_more_data()
is called in the following conditions for PPS header: NalReader
reached position 20, 12 bits are remaining and trailing data at
current byte position is c8 00.
rbsp_more_data() used to return TRUE whereas it should obviously
return FALSE because x8 00 represents a valid rbsp_trailing_bits()
structure.

Effective for the case where we have a platform that does not
require a native window. We require a mainloop to run the GL
commands which is currently operated by GstGLWindow.
Intel drivers require the display handles be the same for context
sharing to occur. Also solves some cases of use after free of the
display when integrating with gstreamer-vaapi.
See https://bugs.freedesktop.org/show_bug.cgi?id=41736 for the intel bug.
GstGLDisplayX11 holds the display connection and name. Each thread requires
it's own X11 Display connection (initialised from name) due to the fact that
we do not want to call XInitThreads(). Doing so would result in segfaults
when integrating with GUI toolkits Gtk, Qt, etc.
The Display connection is for OpenGL platforms where a constant display is
required in order to share contexts (egl). In the case of a wrapped context
(added later), we do not have GstGLWindow to retreive the display from so a
'master' connection is used instead.
