Up until now, various subtitle decoders have not cleaned up
the AVSubtitle on error; this task must not be left to the user
because the documentation explicitly states that the AVSubtitle
"must be freed with avsubtitle_free if *got_sub_ptr is set"
(which it isn't on error).
Leaks happen upon failure in ff_ass_add_rect() or in
ass_decode_frame(); freeing generically also allows to remove
now redundant freeing code in pgssubdec and dvbsubdec.
While just at it, also reset got_sub_ptr generically on error.

This piece of code has been added as FFmpeg's answer to
infinite loops in try_decode_frame() in commit
6072a19b4f. There is no loop
around try_decode_frame() any more, so this code can be removed.
This code is only triggered in case a) the codec parameter could
not be determined, b) the decode delay could not be guessed or
c) no packet was ever encountered and the encoder has the
AV_CODEC_CAP_CHANNEL_CONF. In these cases the new code will
no longer emit a "decoding for stream %d failed" message, which is
prima facie false. In case a) an additional "Could not find codec
parameters" message is (and will be) emitted. No warning will be
emitted any more in case b) (this happens e.g. with some
h264-conformance FATE-files).

Support for mapping/unmapping hardware frames has been added into
libplacebo itself, so we can scrap this code in favor of using the new
functions. This has the additional benefit of being forwards-compatible
as support for more complicated frame-related state management is added
to libplacebo (e.g. mapping dolby vision metadata).
It's worth pointing out that, technically, this would also allow
`vf_libplacebo` to accept, practically unmodified, other frame types
(e.g. vaapi or drm), or even software input formats. (Although we still
need a vulkan *device* to be available)
To keep things simple, though, retain the current restriction to vulkan
frames. It's possible we could rethink this in a future commit, but for
now I don't want to introduce any more potentially breaking changes.
LSX and LASX is loongarch SIMD extention.
They are enabled by default if compiler support it, and can be disabled
with '--disable-lsx' '--disable-lasx'.

ffmal_add_packet() basically duplicated the logic in

created a reference even if one is already available.

extra_data and normal packets (from ff_decode_get_packet) processing do
not overlap, thus we can re-use the spare AVPacket to send to
ffmmal_add_packet.
Furthermore, this removes allocation of AVPacket on the stack and stops
using deprecated av_init_packet.

MMAL is an fundamentally an asynchronous decoder, which was a bad fit
for the legacy dataflow API. Often multiple packets are enqueued before
a flood of frames are returned from MMAL.
The previous lockstep dataflow meant that any delay in returning packets
from the VPU would cause ctx->queue_decoded_frames to grow with no way
of draining the queue.
Testing this with mpv streaming from a live RTSP source visibly reduced
latency introduced by frames waiting in queue_decoded_frames from
roughly 2s to 0.

Otherwise there is no way to detect an error returned by avio_close() because
ff_format_io_close cannot get the return value.
Checking the return value of the close function is important in order to check
if all data was successfully written and the underlying close() operation was
successful.
It can also be useful even for read mode because it can return any pending
AVIOContext error, so the user don't have to manually check AVIOContext->error.
In order to still support if the user overrides io_close, the generic code only
uses io_close2 if io_close is either NULL or the default io_close callback.

The current checks just check whether the boxes fit into the remaining
size of the packet instead of whether they actually fit into the box
size. This has been changed; part of this change is to pass the size of
the box (minus the box header) as parameter instead of a pointer to
the AVPacket by which the box parsing function is supposed to
recalculate whether enough data is available.
