This code has been added in f5957f3fe2
when support for WMV1 has been added. It was needed for decoding
inter macroblocks, as WMV1 uses a different scantable and
the ScanTable and ScanTable.raster_end was not yet introduced
(the H263 unquantize function instead used a hardcoded version
of ff_zigzag_direct's raster_end). In other words,
there is no reason to continue to do so for WMV1 inter blocks.
(Apart from that: WMV1 inter blocks don't use
dct_unquantize_h263_inter any more, as unquantizing happens
when parsing the block via specialized RL VLC tables.)
It is also not needed for WMV1/2 intra blocks (for non-ac_pred
it uses the correct ScanTable used by the h263 unquantize
intra function; for ac_pred, the number is overridden)
as well as for WMV2 inter-blocks (raster_end is not really
used in this case; the ordinary ScanTable is used in case
abt_type is zero, otherwise there are two different ScanTables
and block_last_index is overridden in wmv2dec.c).

This decoder unquantizes while parsing blocks
and does not use dct_unquantize_mpeg1_intra
(which uses *_dc_scale) at all.

MotionEstContext contains pointers (to function pointers) that
have been set on a per-frame basis depending upon no_rounding
in ff_me_init_pic() to avoid branches like these. Also makes
MotionEstContext more independent of MpegEncContext.

The mpegvideo-based encoders do one uncommon thing with
the packet's data given by ff_alloc_packet(): They potentially
reallocate it. But this only affects the internal buffer
and is not user-facing at all, so one can nevertheless
use the AV_CODEC_CAP_DR1 for them.

When there are multiple candidates for macroblock type, the encoder
tries them all. In order to do so, it keeps several sets of states
containing the variables that get modified when encoding
the macroblock and in the end uses the best of these.
Yet one variable was set, but not included in this state:
The current macroblock's qscale value in the current picture's
qscale_table. This may currently be set multiple times in
mpv_reconstruct_mb(), yet it is read when adaptive_quant is true.
Currently, the value read can be the value set by the last attempt
to write the current macroblock and not the initial value.
Fix this by only setting the qscale_table value in one place
outside of mpv_reconstruct_mb() (where it does not belong at all).

The idea is to split the 16 bit coefficients into lower and upper half,
invoke udot for the lower half, shift by 8, and follow by udot for the
upper half.

ff_decode_frame_props() injects global side data passed by the caller (Usually
coming from the container) but ignores the global side data the decoder
gathered from the bitstream itself.

This simplifies the code, reduces allocations, and critically, does
not store references of frames, along with references to hw_frames_ctx.
The issue was that storing refs to frames while transferring stored
refs to hw_frames_ctx of frames, and so created a circular dependency,
which caused the Vulkan device to never be terminated.
This only stores what it strictly needs as a dependency, and enables
the frames context to be freed, even while doing asynchronous transfers.
It prevents the filter of running in case such option is missing,
failing early, during init() instead of simply logging an error
during runtime.

The change has caused regressions for many users and consumers.
Playlist reloads only happen when a playlist doesn't indicate that it
has ended (via #EXT-X-ENDLIST), which means that the addition of future
segments is still expected.
It is well possible that an HLS server is temporarily unable to serve
further segments but resumes after some time, either indicating a
discontinuity or even by fully catching up.
With a segment length of 3s, a max_reload value of 1000 corresponds to
a duration of 50 minutes which appears to be a reasonable default.

The issue is that this could consume gigabytes of VRAM at higher
resolutions for not that much of a speedup.
Automatic detection was not a good idea as we can't know how much
VRAM is actually free.
Just remove it.
