Merged-by: James Almer <jamrial@gmail.com>

Aliased compressed AAC bytes are almost certainly not meaningful SBR
data. In the wild this causes harsh artifacts switching HE-AAC streams
that don't have SBR headers aligned with segment boundaries.

Turning off SBR falls back to a default set of upsampling parameters
that can function as a sort of error concealment. This is consistent
with how the decoder handles other sorts of errors.

Fixes memleak.

It was done on a whim because of the FATE header check and was actually
meant to be removed before pushing.

Also, nobody in review spotted it.

This commit is a noop. We use isNBPS() in these places instead since
d736b52a. is9_15BPS() wouldn't be a good name in our codebase due to

  swscale: Update bitdepth range check

This commit is a noop.

Up to 14 bits is supported since fa36f334. This commits pushes the
limit to 15 bits but we don't seem to have pixel formats that enters in
that category.

12:03 <ubitux> so what's your opinion? should we move to 15 even if unused currently to make it consistent with libav and the function names, or keep our 14 suggesting there might be an issue with 15?
12:05 <ubitux> (functions are called hScale8To15_c, hScale16To15_c, ff_hscale8to15, ...)
12:06 <michaelni> I prefer to keep 14 until theres a case that allows us to test this and i suspect it will not work with 15 at least not all the code

Merged-by: Clément Bœsch <u@pkh.me>

Avoids reading from uninitialized memory, regression since af1761f7

libavcodec now automatically serializes decoding for hwaccels which
are not thread-safe. This means API users, which rely on the libavcodec
native software fallback mechanism, can now simply enable threading
without running into problems.

Whatever it was supposed to do.
