6f2ab31d10 h265parser: Calculate short term RPS size in slice header
The calculated size of short_term_ref_pic_set is not a part of
HEVC syntax but the value is used by some stateless decoders
(e.g., vaapi, dxva, vdpau and nvdec) for the purpose of skipping
parsing the syntax by the accelerator.

52f2054386 h265parser: Various update of vps parsing
* Add FIXME for future correction of HRDParames parsing.
Spec. defines that the number of HRDParames could be up to
"vps_num_layer_sets_minus1 + 1" (i.e., 1024).

* Add parsing vps_base_layer_{internal,available}_flag.

* Fix possible invalid vps_extension parsing.

Fixes #798

a05006944a codecparsers: GST_EXPORT -> GST_CODEC_PARSERS_API
We need different export decorators for the different libs.
For now no actual change though, just rename before the release,
and add prelude headers to define the new decorator to GST_EXPORT.

977af86e8b h265parser: parse extra profile fields
Those fields have been introduced in version 2 and later to define new
profiles like the format range extensions profiles (A.3.5).

NOTE: This patch breaks the parser ABI, rebuild needed.

d252f503fc h265parser: decouple GstH265Profile and GstH265ProfileIDC
We used to have the same enum to represent H265 profiles and idc values.
Those are no longer the same with extension profiles defined from
version 2 of the spec.
Split those enums so the semantic of each is clearer and we'll be able
to add extension profiles to GstH265Profile.

Also add gst_h265_profile_tier_level_get_profile() to retrieve the
GstH265Profile from the GstH265ProfileTierLevel. It will be used to
implement the detection of extension profiles.

54c2620bdb codecparsers: h265: Fix tile row and column parsing
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.

497f372668 codecparsers: h265: Add APIs for up-right-diagonal/raster scan conversion
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.
