'extern inline' was added in 2fb76c89 for MSVC (it was just
'inline' before), but all of this doesn't really make sense,
the functions are not going to be inlined anyway, and what
'extern inline' means exactly also appears to depend on the
Cxx standard targetted. Let's just remove the 'extern inline'
entirely. At least gcc6 still emits the exact same code as
before anyway. Fixes compilation/linking with gcc 4.8 as
used on L4T on the TK1.

Highlights of the features provided are:
* Faster builds on Linux (~40-50% faster)
* The ability to build with MSVC on Windows
* Generate Visual Studio project files
* Generate XCode project files
* Much faster builds on Windows (on-par with Linux)
* Seriously fast configure and building on embedded
... and many more. For more details see:

Building with Meson should work on both Linux and Windows, but may
need a few more tweaks on other operating systems.
The subsampling_x, subsampling_y, bit_depth, color_space and color_range
fileds are moved from GstVp9FrameHdr to the global GstVp9Parser structure.
These fields are only present in keyframe or intra-only frame, no need to
duplicate them for inter-frames. This is an ABI change.

This is a regression from since mpegvideoparser was switched to
use the codecparsing library.
The problem is that the high bit of the profile_and_level is used
to specify non-hierarchical profiles and levels. Unfortunately we
were discarding that information.
Expose that escape bit, and use it in the element

H.265 7.4.7.1 says:
> When slice_deblocking_filter_disabled_flag is not present, it is

Initialize to 0 these parse structures before filling them: GstH264SEIMessage,
GstH264NalUnit, GstH264PPS, GstH264SPS and GstH264SliceHdr.
When calling the functions which fill those structures, they may fail, leaving
unitialized those structures. This situation may lead to future problems, such
as a segmentation fault when freeing, for example.
This patch initializes to zero these structures, before filling them.

If short_term_ref_pic_set_sps_flag is FALSE, the ShortTermRefPicSet
structure is supposed to derive from slice header. Which means,
CurrRpsIdx is equal to num_short_term_ref_pic_sets. But the number
of refpicsets communicated via sps header is only num_short_term_ref_pic_sets - 1.
And we are using slice_header structure to reference the last entry, which is
ShortTermRefPicSet[num_short_term_ref_pic_sets].

Section 6.5.1: Coding tree block raster and tile scanning conversion process
Follow the equations 6-3 and 6-4
This will provide correct offset_max in slice_header for parsing
num_entry_point_offsets.

As per 7-42 and 7-43 the ScalingFactor's scanIdx is 0,
which is "up-right-diagonal" scan. Add APIs for converting
up-right-diagonal to raster and vise versa.

Being more strict on specification, According to 7.4.7.3,
delta_chroma_log2_weight_denom should be in the range of
[(0 - luma_log2_weight_denom), (7 - luma_log2_weight_denom)]

The SPS struct might be filled out by a call to
gst_h264_parser_parse_subset_sps, which fills out
dynamically allocated data and requires a call
to gst_h264_sps_clear() to free it. Also make sure
to clear out any allocated SPS data when returning
an error.

ChromaLog2WeightDenom = luma_log2_weight_denom + delta_chroma_log2_weight_denom
The value of ChromaLog2WeightDenom should be in the range of 0 to 7 and
the value luma_log2_weight_denom should be also in the range of 0 to 7.
Which means , delta_chroma_log2_weight_denom can have values in the range
between -7 and 7.
