Sometimes, if pthread_create() failed, then pthread_cond_wait() could
accidentally be called in the worker threads after the uninit function
had already called pthread_cond_broadcast(), leading to a deadlock.

Don't call pthread_cond_wait() if c->done is set.

Elaborate on flushing the decoder.

The packet data does not need to be aligned.

Handle it in the same way as VP6F, except for the codec tag.

The plain VP6 format is vertically flipped compared to VP6F/VP6A.
Support for the plain VP6 format was added in 09d8c0ae (which
also introduced support for muxing VP6F properly in general).

In these cases, there is no extradata but only the properly set
width/height values by the demuxer.

This makes sure VP6 in F4V files is cropped properly.

This is similar to what is done for H264 for letting the container
width/height override what's in the bitstream, since 30f51509.

The Mach-O bug was fixed in yasm 0.8.0 and we don't
support versions that old anymore.
Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

This is in preparation for removing a .rodata kludge
which was only required for older YASM versions.

The movbe instruction was introduced in 0.8.0, which already
had AVX, which was introduced in 0.7.0, and NASM introduced
movbe in 2.0.3, which is the same version which introduced
AVX support.

Also, make the failure message more accurate.

Prevents a crash if the misaligned exception mask bit is
cleared for some reason.

Misaligned SSE functions are only used on AMD Phenom CPUs
and the benefit is miniscule. They also require modifying
the MXCSR control register and by removing those functions
we can get rid of that complexity altogether.
