  h264_ps: when parsing a VUI fails, only abort when explode is set

Merge only for metadata, ignoring invalid data can put the context
into an invalid state and can possibly be used for remote code
execution exploits.
Also we support all non standard VUIs that have been reported so
ignoring parsing failure makes no sense for us unless theres
some issue that has not been reported

94603feb1b h264_ps: when parsing a VUI fails, only abort when explode is set 
A VUI doesn't contain anything strictly necessary for decoding.
Apparently there are many samples with truncated VUIs in the wild, this
commit should allow decoding them.

2ef1e62c8d correct the AVOption documentation for AV_EF_CAREFUL 
The flag was and is intended to be a sane default and thus does not enable
time consuming checks. This also matches how the flag is used in decoders and
demuxers.

Don't use word-size multiplications if size == 2, and if we're using
SIMD instructions (size >= 8), complete leftover 4byte sets using movd,
not mov. Both of these changes lead to minor speedups.
