Tested with the alphaconformanceG sample.

Fixes CID 1419836.

(cherry picked from commit 9ed18f30)

Helps with use cases such as static linking, as the .pc file
does actually contain the necessary Libs.private entries for all
required dependencies.

This starts a new section - 3.4 has been released.

Use the appropriate metadata filter for each codec - in the absence of any
options to modify the stream, the output bitstream should be identical to
the input (though the output file may differ in padding).

All tests use conformance bitstreams, the MPEG-2 streams are newly added
from the conformance test streams

(cherry picked from commit 3cae7f8b)
(cherry picked from commit fbd63170)

(cherry picked from commit 10eb496d)

Matching the H.264 encoder.

(cherry picked from commit e3e8eab3)

Also improves the metadata and generally makes the configuration
a bit cleaner.

(cherry picked from commit ac124867)

This should be ticks, not time_scale steps - it was wrong for all
framerates not a multiple of 1/2.

(cherry picked from commit 30645174)

Included by default with non-IDR intra frames.

(cherry picked from commit a49ee60d)

Adds a new private option to enable them (off by default).

(cherry picked from commit 820a4483)

(cherry picked from commit 7a4fac5e)

(cherry picked from commit b78c30d7)

This will be used later in both the mpeg2_metadata filter and the
VAAPI MPEG-2 encoder.  Also adds a unit test.

(cherry picked from commit b5859e0b)

This is able to modify some header metadata found in the VPS/SPS/VUI,
and can also add/remove AUDs.

(cherry picked from commit b31a9eae)

This applies a specific fixup to some Blu-ray streams which contain
redundant PPSs modifying irrelevant parameters of the stream which
confuse other transformations which require correct extradata.

A new single global PPS is created, and all of the redundant PPSs
within the stream are removed.

(cherry picked from commit e6874bc3)

This is able to modify some header metadata found in the SPS/VUI,
and can also add/remove AUDs and insert user data in SEI NAL units.

(cherry picked from commit 9e93001b)
(cherry picked from commit c42b62d1)

Supports all streams that the coded bitstream infrastructure does
(currently H.264, H.265 and MPEG-2).

(cherry picked from commit 18f1706f)
(cherry picked from commit 44cde38c)

Add comments to describe the sources of the constraint values expressed here,
and add some more related values which will be used in following patches.

Fix the incorrect values for SPS and PPS count (they are not the same as those
used for H.264), and remove HEVC_MAX_CU_SIZE because it is not used anywhere.

(cherry picked from commit b88da98b)

With comments describing the derivation of each value.
