b347384173 avcodec/me_cmp: Remove ff_check_alignment() 
The usage of a static variable presents a potential for data races and
means that this function can't be used in init functions of codecs with
FF_CODEC_CAP_INIT_THREADSAFE (unless of course one presumes that
everything is alright in which case the error is not triggered; but then
the whole function is pointless...). This makes the Snow decoder
init-threadsafe as it already claims.

Notice that this function has been removed in 2014 by Libav in commit
9103185bd1, because only some codepaths
are checked this way and because it only affects legacy compilers. The
latter is of course even more true today.

d64828c8af avcodec/Makefile: Remove FLAC dependencies on vorbis_data 
2ef2496cd1 used ff_vorbis_channel_layouts
in flac.c, but added a dependency to the FLAC decoder only; lateron
aba0278e9f added the dependency of the
FLAC parser and encoder on vorbis_data.o. Yet when the original commit
was reverted in aba0278e9f, the two other
dependencies were not removed. This commit fixes this.

a423bc9dc2 ffmpeg_opts: remove lowres check 
The st->codec values are updated based on the lowres factor by
avformat_find_stream_info() when it runs an instance of the decoder internally,
and the same thing happens in ffmpeg.c when we open ist->dec_ctx with
avcodec_open2(), so these assignments are redundant.

Alternatively this could be ignored but then the end condition of the loop
would be hard to reach as avio_tell() is int64_t
