swscale/x86/rgb2rgb: optimize AVX2 version of uyvytoyuv422
Currently the AVX2 version of uyvytoyuv422 in the SIMD loop does the following:
4 vinsertq to have interleaving of the vector lanes during load from memory.
4 vperm2i128 inside 4 RSHIFT_COPY calls to achieve the desired layout.

This patch replaces the above 8 instructions with 2 vpermq and
2 vpermd with a vector register similar to AVX512ICL version.

Observed the following numbers on various microarchitectures:

ffmpeg_demux: set default for readrate_catchup to be 5% faster
The existing default value is the same as the primary readrate.
This maintains the flow rate as best as possible but does not
reduce the lag. This new value allows catchup to gradually happen
without overwhelming the receiver.

Addresses a concern brought up in #11469

ffmpeg: add per-stream input option drop_changed
This is a replacement in ffmpeg for the deprecated avcodec flag AV_CODEC_FLAG_DROPCHANGED.

This option is meant to be used when the filtergraph should not be
reinited upon input parameter changes as that leads to loss of state
in the filtergraph potentially leading to broken or aborted output,
e.g. inserting of silence with first_pts specified in aresample.

Generally useful to avoid corrupted yet decodable packets in live
streaming inputs.

This option when enabled takes precedence over reinit_filters

avcodec/ffv1: Implement 2D RLE for remap
ATM this performs as well or better as any other algorithm tried.
Its simple for the decoder.
On the encoder side complexity depends on how parameters are
chosen. But with a fixed mul_count of 1 and basic heuristic
it performs as well as any more complex choice i tried so far.

The encoder code here is flexible and allows mul_count > 1
and also can easily be used to exactly test various parameters.

With mul_count=512 we can gain another 6% in remap table size
for fixed point in float data. (this is not implemented in this
patch though)

avcodec/mpeg12enc: Merge ff_mpeg1_encode_init() into ordinary init
Everything except setting the dc_scale_tables can be done
before calling ff_mpv_encode_init(); setting the dc_scale_tables
unfortunately still has to be performed via a (now inlined)
callback performed by ff_mpv_encode_init() as it relies
on intra_dc_precision having been sanitized.

avcodec/mpeg12enc: Don't write invalid MPEG-1 slice headers
The valid values for slice_start_code are 0x1..0xAF, which implies
that one can't start a slice with row nb > 174 (zero-based).
This problem can be encountered with files of sufficient height
(more than 2800 pixels) either by using the slice option or by
imposing an RTP payload limit.

Fix this by making the last slice start on the maximum allowed
slice row if necessary and divide the first 174 rows to the remaining
slices. This will impede parallelism both in the decoder and encoder,
but that is unavoidable.

avutil/slicethread: Remove NULL pointer check when freeing
avpriv_slicethread_free() is one of our functions that takes
a pointer to a pointer and resets the pointer when done.
It is legal for such functions to be passed a pointer to a NULL

avcodec/mpegvideo_enc: Use func ptr for encoding macroblocks
It gets rid of a switch (with accompanying CONFIG_*_ENCODER checks);
for MJPEG, it even lets one perform the check for whether one is
really encoding or only recording the macroblock once during init.

Furthermore, the switch actually contained lots of dead code --
it is compiled three times (for different pixel formats: 420, 422, 444),
yet most encoders only support 420. The approach used here automatically
fixes this.

avcodec/msmpeg4dec: Avoid lookups when decoding motion vector
Up until now, the decoder uses VLCs to determine whether
this is an escape element or an index in two separate tables
giving the x and y components of the motion vector.
Given that both these components fit into an int16_t and therefore
into a VLCElem's symbol one can simply use a symbol table
to avoid the latter lookups.

This necessitated to combine the two tables for x and y components.
While just at it, also switch to ff_vlc_init_tables_from_lengths().
This will allow to get rid of the code tables (about 4KiB) once
the encoder has been ported, too.

avcodec/mpegvideo: Move allocating encoder buffers to mpegvideoenc.c
dct_error_sum and me.map are allocated per slice-context
and therefore their allocation has not been moved to
mpegvideoenc.c in 0154fb43e328b13da8943e66b38dc1b5ab9315af.

This commit changes this by allocating them jointly and
moving said allocations to mpegvideo_enc.c like the other
encoder-only buffers.
The buffers are suitably aligned to ensure that no false
sharing occurs.

avcodec/mpegvideoenc: Add MPVEncContext
Many of the fields of MpegEncContext (which is also used by decoders)
are actually only used by encoders. Therefore this commit adds
a new encoder-only structure and moves all of the encoder-only
fields to it except for those which require more explicit
synchronisation between the main slice context and the other
slice contexts. This synchronisation is currently mainly provided
by ff_update_thread_context() which simply copies most of
the main slice context over the other slice contexts. Fields
which are moved to the new MPVEncContext no longer participate
in this (which is desired, because it is horrible and for the
fields b) below wasteful) which means that some fields can only
be moved when explicit synchronisation code is added in later commits.

More explicitly, this commit moves the following fields:
a) Fields not copied by ff_update_duplicate_context():
dct_error_sum and dct_count; the former does not need synchronisation,
the latter is synchronised in merge_context_after_encode().
b) Fields which do not change after initialisation (these fields
could also be put into MPVMainEncContext at the cost of
an indirection to access them): lambda_table, adaptive_quant,
{luma,chroma}_elim_threshold, new_pic, fdsp, mpvencdsp, pdsp,
{p,b_forw,b_back,b_bidir_forw,b_bidir_back,b_direct,b_field}_mv_table,
[pb]_field_select_table, mb_{type,var,mean}, mc_mb_var, {min,max}_qcoeff,
{inter,intra}_quant_bias, ac_esc_length, the *_vlc_length fields,
the q_{intra,inter,chroma_intra}_matrix{,16}, dct_offset, mb_info,
mjpeg_ctx, rtp_mode, rtp_payload_size, encode_mb, all function
pointers, mpv_flags, quantizer_noise_shaping,
frame_reconstruction_bitfield, error_rate and intra_penalty.
c) Fields which are already (re)set explicitly: The PutBitContexts
pb, tex_pb, pb2; dquant, skipdct, encoding_error, the statistics
fields {mv,i_tex,p_tex,misc,last}_bits and i_count; last_mv_dir,
esc_pos (reset when writing the header).
d) Fields which are only used by encoders not supporting slice
threading for which synchronisation doesn't matter: esc3_level_length
and the remaining mb_info fields.
e) coded_score: This field is only really used when FF_MPV_FLAG_CBP_RD
is set (which implies trellis) and even then it is only used for
non-intra blocks. For these blocks dct_quantize_trellis_c() either
sets coded_score[n] or returns a last_non_zero value of -1
in which case coded_score will be reset in encode_mb_internal().
Therefore no old values are ever used.

The MotionEstContext has not been moved yet.

avcodec/ppc/mpegvideo_altivec: Use correct inter scantable
This affected the WMV1/2 encoders (but not when running FATE because
the encoding part uses the fastint dct, so this code isn't used
then anyway).

It did not affect anything else, because a) only WMV1/2 use different
scantables, b) ff_msmpeg4_decode_block() (and therefore the WMV1
decoder) already unquantize inter macroblocks as they are parsed
c) the WMV2 decoder does not use the unquantize functions for inter
macroblocks at all.

avcodec/ppc/mpegvideo_altivec: Don't process coeffs as scalars
block_last_index and nCoeffs is an optimization designed
to avoid processing unnecessarily many coefficients; yet
it would be legal to always process all coefficients
(all coefficients beyond nCoeffs are zero anyway and
zeros are always unquantized to zeros). Therefore
one does not need a scalar tail.

avcodec/mpegvideo: Only keep the actually used unquantize funcs
For all encoders and all decoders except MPEG-4 the unquantize
functions to use don't change at all and therefore needn't be
kept in the context. So discard them after setting them;
for MPEG-4, the functions get assigned on a per-frame basis.

Decoders not using any unquantize functions (H.261, MPEG-1/2)
as well as decoders that only call ff_mpv_reconstruct_mb()
through error resilience (RV30/40, the VC-1 family) don't have
the remaining pointers set at all.
