Expose the expose() and set_render_rectangle() methods. These are useful for
proper functioning of the video overlay in various situations and toolkits.
In very few cases the simple version was actually needed and having the
parameters hidden by a _full() version caused application that actually needed
it to not use it.
The base class is useful for having multiple backing memory types other
than the default. e.g. IOSurface, EGLImage, dmabuf?
The PBO transfer logic is now inside GstGLMemoryPBO which uses GstGLBuffer
to manage the PBO memory.
This also moves the format utility functions into their own file.
Heavily based on GstGLBaseBuffer that is a subclass of GstGLBaseMemory.
Provides GPU and CPU accessible GL buffer objects by GL handle or by
sysmem data pointer.
Keep the libs in alphabetical order unless a specific link order is required.
Also remove the -L directives as we specify the direct path to the .la files.
steal_buffer() + unref seems to be a wide-spread idiom
(which perhaps indicates that something is not quite
right with the way aggregator pad works currently).
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.

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)
Fix routine names for zigzag/raster scan order conversion routines for
quantization matrices. This ought to use the gst_h264_quant_matrix_*()
naming convention instead of gst_h264_video_quant_matrix_*(), which
derived from the MPEG-2 function names.

Add a new function to calculate video stream framerate which rely on
SPS, slice header and pic timing using formula:
time_scale 1 1
fps = ----------------- x --------------- x ------------------------
num_units_in_tick DeltaTfiDivisor (field_pic_flag ? 2 : 1)
See section E2.1 of H264 specification for definition of variables.
