The advantage of this is that the is32x32 division branch in
decode_coeffs_b is removed from the inner loop to outside the block
coef decoding loop in decode_coeffs. Also, it allows us to merge the
txsz branches from the block coef decoding loop, the context merge
and the context split.

Currently the file overwrite check does not work for paths that
contain a colon.
Use avio_find_protocol to always execute the existence check if
the file protocol is going to be used.
Fix remaining part of ticket #3249.

I found the optimisation of 2 samples per iteration obscured the
underlying algorithm. I had to write it out on paper and translate into
a mathematical sum to see that the two samples are unconnected. I hope
that if anyone else is struggling to understand the code that this will
be useful.

vector_fmul and vector_fmac_scalar are guaranteed that they can process in
batch of 16 elements, but their SSE versions only does 8 at a time.
Therefore, unroll them a bit.
299 to 261c for 256 elements in vector_fmac_scalar on Arrandale/Win64.
