The private options chromaoffset, sc_threshold, and noise_reduction
were set to 0 rather than -1, and were always initializing values
in libx264 rather than letting the library use its default.

After the merge the default threshold was unconditionally overwritten

A similar fix was written by Vittorio Giovara, but i didnt see that before
i wrote this and it also doesnt apply cleanly

This uses a new MMAL feature, which limits the number of extra frames
that can be buffered within the decoder. VIDEO_MAX_NUM_CALLBACKS can
be defined as positive or negative number. Positive numbers are
absolute, and can lead to deadlocks if the user underestimates the
number of required buffers. Negative numbers specify the number of extra
buffers, e.g. -1 means no extra buffer, (-1-N) means N extra buffers.

Set a gratuitous default of -11 (N=10). This is much lower than the
firmware default, which appears to be 96.

This is backwards compatible, but needs a symbol only present in newer
firmware headers. (It's an enum item, so it requires a check in
configure.)

I guess this means part 2 in both cases. Not sure which profiles exactly
are actually supported properly.

Slight simplification. The result is the same. Also, change the
wording of the message as requested in patch review.

The mmal decoders do not depend on the software decoders.
