Changelog: add an entry for deprecating the avconv -vol option
fate: image: Add dependencies
AAC SBR: use AVFloatDSPContext's vector_fmul

Around 5% speedup on the code block using 'vector_fmul_add's.

SBR DSP x86: implement SSE sbr_hf_gen

Start and end index are multiple of 2, therefore guaranteeing aligned access.
Also, this allows to generate 4 floats per loop, keeping the alignment all
along.

Timing:
- 32 bits: 326c -> 172c
- 64 bits: 323c -> 156c

fate: dpcm: Add dependencies
flac: change minimum and default of lpc_passes option to 1

Avoid use of uninitialized and uncomputed linear least square models
during ff_lpc_calc_coefs() for FF_LPC_TYPE_CHOLESKY. Fixes running
make fate-flac-16-lpc-cholesk with valgrind --undef-value-errors=yes.
mov: compute avg_frame_rate only if duration is known

Fixes an assert in fuzzed sample sample.mp4_s265930.
mov: validate number of DataReferenceBox entries against box size

Avoids a 2G memory allocation and parsing of random data in
mov_read_dref(). The fuzzed sample sample.mp4_s224424 triggers this.
h264: check sps.log2_max_frame_num for validity

Fixes infinite or long taking loop in frame num gap code in
the fuzzed sample bipbop234.ts_s223302.

h264: add a pointer for weighted prediction temporary buffer

Reusing MpegEncContext's obmc_scratchpad for this becomes a mess with
adaptive frame-mt.
lavf/pcm: check size, do not produce invalid packets

Inspired by 92b8c9d89e7ae86bffa05393bb230d5a165b0148.

lavfi/alphaextract: drop cur_linesize = out_linesize branch in draw_slice()

The code causes uninitialized data copy, and may be actually slower than
a loop over each line in case the padding is big.
