Merge find_near_mvs and mv bitstream decoding: don't do prediction steps
until absolutely necessary.

s->windowed_samples will always have a range of [-32767,32767] due to the
window function, so the return value from log2_tab() will always be in the
range [0,14].

This code will be later split out into a function which takes a 'size'
argument, so I'm keeping the name 'sizeX' here.

Only trivial splits are done here -- i.e. copy/paste + reindent +
missing variable declarations.

Instead of returning an error when bytes are left over, just return
the number of actually used bytes as other decoders do.
Instead add a special case so an error will be returned when none
of the data looks valid to avoid making debugging a pain.

The function return type is void, so a return statement with an
expression is forbidden (and pointless).

The avcodec_thread_free() compatibility wrapper calls ff_thread_free(),
which is not defined when threading is disabled.  Make this call
conditional.

check AVCodecContext->sample_fmt against AVCodec->sample_fmts[] to ensure
that the encoder supports the specified sample format. Error out if it doesn't.
Previously, it would continue and output garbage. Fixes issue 2587.

Decode times for big_buck_bunny_720p_stereo:

1 thread:
real    1m14.227s
user    1m13.104s
sys     0m1.108s

2 threads: (33% faster)
real    0m49.329s
user    1m33.735s
sys     0m1.834s

3 threads: (44% faster)
real    0m41.593s
user    1m44.884s
sys     0m1.967s

As a side effect of the last commit, avcodec_open() now calls it automatically,
so there is no longer any need for clients to call it.
Instead they should set AVCodecContext.thread_count.

avcodec_thread_free() is deprecated, and will be removed from avcodec.h at the
next MAJOR libavcodec bump.

Rename the functions to ff_thread_init/free, since they are now internal.
Wrappers are provided to maintain API compatibility.

Also allow qmin/qmax to go up to 69 (the current max value for libx264).  This
will have to increase when we add 9/10-bit support.

Due to being pants-on-head retarded, libavcodec defaults this to zero, which
results in broken output.  This didn't affect ffmpeg.c, which sets it itself,
but caused problems for other calling apps using VBV.
