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.

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 30f515091.

Store XMM6 and XMM7 in the shadow space in functions that
clobbers them. This way we don't have to adjust the stack
pointer as often, reducing the number of instructions as
well as code size.

This avoids building mmxext and sse2 code when disabled by configure.

The function does not depend on MMX and compilation without MMX enabled
fails if the function is compiled conditional on MMX availability.
