5ae05bb42a codecparsers: Defering computation of pps and sps fields
While possible defer computataion of pps and sps fields until
slice parsing since it may happens that bitstreams don't encoded
them in expected order.
A example weird ordered bitstreams is VPSSPSPPS_A_MainConcept_1
conformance test.

74a811e718 codecparsers: h265: Introduce long_term_ref_pic_set_size
This is the size of the `if( long_term_ref_pics_present_flag )` inside
slice_segment_header( ) syntax. This size in bit, and after de-emulation
is needed by some HW.

be84fc23ca h265parser: Add a new NAL parsing API to handle malformed packets
Add gst_h265_parser_identify_and_split_nalu_hevc() method to
handle a case where packetized stream contains start-code prefix.
This new method behaves similar to exisiting gst_h265_parser_identify_nalu_hevc()
but it will scan start-code prefix to split given data into
NAL units.

9ec4041a51 codecparsers: bitwriter: Calculate PicSizeInCtbsY when writing slice header.
The slice->pps->PicWidthInCtbsY/PicHeightInCtbsY values are calculated when
 we parse the slice header. But they are not calculated in bitwriter and so
 may not have valid value when writing slice header.

d4f9676c9c h265parser: Fix short_term_ref_pic_set() size calculation
This field is used by DXVA/NVDEC/VA, and each specification
describes (NVDEC is not well documented) that it's the number of
bits used in short_term_ref_pic_set().

DXVA doesn't explicitly mention that whether the size of
emulation preventation bytes (EPB) is inclusive or not, but
VA is clearly specifying that it's the size after removing
EPB. Excluding EPB size here makes more sense therefore.

049655c824 codecs: av1: Fix state when we show existing keyframe
Showing existing keyframe have special meaning in AV1. All the references
frame will be refreshed with the original keyframe information. The refresh
process (7.20) is implemented by saving data from the frame_header into the
state. To fix this special case, load all the relevant information into the
frame_header.

As there is nothing happening in between this and the loading of the key-frame
into the state, this patch also remove the separate API function, using it
internally instead.

Fixes #1090

05ee44b62b codecparsers: h265parser: return invalid profile if len is 0.
Though the profiles[0] is inited as GST_H265_PROFILE_INVALID in the
gst_h265_profile_tier_level_get_profile(), the profile detecting may
change its content later. So the return of profiles[0] may not be an
invalid profile even the len is 0.

9eb0f8501f codecparsers: h265parser: Fix the index incrementation error in append_profile().
The current "*idx++" operation just refers the pointer and increment the pointer
itself, not the content of the pointer. This causes that the count of the profiles
is always 0.

5905955cc3 av1parser: Fix data type of film grain param
Fix cb_offset and cr_offset data type from guint8 to guint16. According
to spec, cb_offset and cr_offset are 9 bit long, while guint8 can cause
interger overflow, and thus change to guint16.

3040a26073 codecparsers: h265parser: Use a table map to get profile.
Instead of a sequence of if statements, declare a table to map profile
idc with profiles and traverse it.

Also, first add the profile from the parsed profile idc and later add,
into the profile array, the profile from the compatibility flags.

168ad9f58f codecparsers: h265parser: Verify all possible profiles.
It's possible a HEVC stream to have multiple profiles given the
compatibility bits. Instead of returning a single profile, internal
gst_h265_profile_tier_level_get_profiles() returns an array with all
it possible profiles.

Profiles are appended into the array only if the generated profile
is not invalid.

gst_h265_profile_tier_level_get_profile() is rewritten in terms of
gst_h265_profile_tier_level_get_profiles(), returning the first
profile found the array.

And  gst_h265_get_profile_from_sps() is also rewritten in terms of
gst_h265_profile_tier_level_get_profiles(), but traversing the array
verifying if the proposed profile is actually valid by Annex A.3.x of
the specification.

6e79932ad9 meson: List libraries and their corresponding gir definition
Introduces a `libraries` variable that contains all libraries in a
list with the following format:

``` meson
libraries = [
    [pkg_name, {
        'lib': library_object
        'gir': [ {full gir definition in a dict } ]
    ],
    ....
]
```

It therefore refactors the way we build the gir so that we can reuse the
same information to build them against 'gstreamer-full' in gst-build
when linking statically
