d7d6efe42b 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.

8cc2fa1e5d 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.

480be07a96 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.

2aef3d66c9 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
