842e98b4d8 pgssubdec: reset rle_data_len/rle_remaining_len on allocation error 
The code relies on their validity and otherwise can try to access a NULL
object->rle pointer, causing segmentation faults.

b7e64fba7f Reduce the scope of some variables 
This avoids unused variable warnings after the next version bump.
Also drop a trace level av_log() call that is in the way.

885a9d6087 pgssub: Fix subpicture colorspace and range 
Widen the values from limited to full range and use BT.709 where it
should be used according to the video resolution:

SD is BT.601, HD is BT.709

Default to BT.709 due to most observed HDMV content being HD.

9779b62624 pgssubdec: fix subpicture output colorspace and range 
Functionality used before didn't widen the values from limited to
full range. Additionally, now the decoder uses BT.709 where it
should be used according to the video resolution.

Default for not yet set colorimetry is BT.709 due to most observed
HDMV content being HD.

BT.709 coefficients were gathered from the first two parts of BT.709
to BT.2020 conversion guide in ARIB STD-B62 (Pt. 1, Chapter 6.2.2).
They were additionally confirmed by manually calculating values.

Fixes #4637

a17a766190 lavc: Add data and linesize to AVSubtitleRect 
Use the new fields directly instead of the ones from AVPicture.
This removes a layer of indirection which serves no pratical purpose
whatsoever, and will help in removing AVPicture structure completely
later.

Every subtitle encoder/decoder seamlessly points to the new arrays,
so it is possible to deprecate AVSubtitleRect.pict.

37bbc9eb8b lavc/pgssubdec: use the PTS from the presentation segment. 
According to the sample for trac ticket #1722, PGS subtitles
are decoded from several packets at the same DTS and varying PTS.
The PTS from the presentation segment seem to be the valid one;
in particular, clear subtitles are too early with the other PTS.
