013ec23cbe swscale: fix gbrap16 alpha channel issues 
Fixes filter-pixfmts-scale test failing on big-endian systems due to
alpSrc not being cast to (const int32_t**).

Also fixes distortions in the output alpha channel values by copying the
alpha channel code from the rgba64 case found elsewhere in output.c.

Fixes ticket 6555.

effd2e7291 speedhq: fix behavior of single-field decoding 
The height convention for decoding frames with only a single field made sense
for compatibility with legacy decoders, but doesn't really match the convention
used by NDI, which is the primary (only?) user. Thus, change it to simply
assuming that if the two fields overlap, the frame is meant to be a single
field and the frame height matches the field height.

f0f8da545d lavc/htmlsubtitles: improve handling broken garbage 
This commit switches off forced correct nesting of tags and only keeps
it for font tags. See long explanations in the code for the rationale.

This results in various FATE changes which I'll explain here:

- various swapping in font attributes, this is mostly noise due to the
  old reverse stack way of printing them. The new one is more correct as
  the last attribute takes over the previous ones.

- unrecognized tags disappears

- invalid tags that were previously displayed aren't anymore (instead,
  we have a warning). This is better for the end user

The main benefit of this commit is to be more tolerant to error, leading
to a better handling of badly nested tags or random wrong formatting for
the end user.

1daacba91f Revert "Revert "lavfi/buffersrc: push the frame deeper if requested."" 
This reverts commit 04aa09c4bc
and reintroduces 0ff5567a30 that
was temporarily reverted due to minor regressions.

It also reverts e5bce8b4ce that fixed FATE refs.
The fate-ffm change is caused by field_order now being set
on the output format because the first frame arrives earlier.
The fate-mxf change is assumed to be the same.
