This is possible by not converting from LSBF to MSBF; instead
add LSBF LUTs.
This approach necessitates reversing the initial values.

ff_dsd2pcm_translate() works internally by converting LSBF input
to MSBF upon reading; its buffer is therefore always MSBF
and should therefore be initialized with MSBF silence;
but this is not true since e3d8963c3c
which this patch effectively reverts.

av_realloc_f() frees the buffer it is given on allocation
failure. But in this case, the buffer is an array of
ownership pointers, causing leaks on error. Furthermore,
the count of pointers is unchanged on error and the codec's
close function uses it to free said ownership pointers,
causing a NPD.
This is a regression since 46412a8935.
Fix this by switching to av_realloc_array().

The alignment of all the parameters in diff_bytes can be
anything the despite the documentation claiming otherwise.
8ecd383122 was based around
said documentation and is therefore insufficient to fix
e.g. the misaligned loads that happen in the huffyuvbgra
and huffyuvbgr24 vsynth FATE-tests.

Use SHLIBOBJS and STLIBOBJS in the Makefiles for avcodec and avformat,

Newer specifications such as H.273 have, and probably will further
in the future add new values to these, so - instead of trying to update
these limits - we should simply check if the values are not set to the
value of "unspecified".
This should allow newer avutil values such as IPT-C2 or YCgCo-R
variants be passed to x265 itself, which apparently does its own
validation further down the line.
* SMPTE ST 2128 IPT-C2 defines the coefficients utilized in DoVi
Profile 5. Profile 5 can thus now be represented in VUI as
{AVCOL_RANGE_JPEG, AVCOL_PRI_BT2020, AVCOL_TRC_SMPTE2084,
AVCOL_SPC_IPT_C2, AVCHROMA_LOC_LEFT} (although other chroma
sample locations are allowed). AVCOL_TRC_SMPTE2084 should in
this case be interpreted as 'PQ with reshaping'.
* YCgCo-Re and YCgCo-Ro define the bitexact YCgCo-R, where the
number of bits added to a source RGB bit depth is 2 (i.e., even)
and 1 (i.e., odd), respectively.
GCC 9-13 do not emit warnings for this at all optimization
levels even when -Wmaybe-uninitialized is not disabled.

This filter only had an AVClass and empty options because up until
recently, avfilter_init_str() errored out when options were provided
for a filter without an AVClass. But setting (generic) options is
necessary to take advantage of timeline support. So with
avfilter_init_str() fixed, the AVClass and the options can be removed.

The documentation for filter arguments states that short options must
precede long options (i.e. those of the form key=value). Yet if
process_options() encounters arguments not abiding by this, it simply
treats short options after a long option as if it were parsing short
options for the first time. In particular, it overwrites options already
set earlier, possibly via other short options. This is not how it is
intended (as a comment in the code indicates).
This commit modifies the code to reject further shorthand options
after a long option has been encountered. After all, avfilter_init_str()
errors out upon unrecognized options, so it is intended to be picky.

Once upon a time, there used to be a LGPL and a GPL ProRes decoder
in FFmpeg; the current decoder evolved from the second of these.
But given that it is now the only ProRes decoder we have, it's file
should simply be named proresdec.c (which also brings it in line with
its header).
