No change, the typo is not part of FFmpeg

* Reduced xmm register count to 7 (As such they are now enabled for x86_32).
* Removed four movdqa (affects the sse2 version only).
* pxor is now used to clear m0 only once.
~5% faster.

bytestream2_* will not cause buffer overflow, but in that case, this means
the allocation would be incorrect and the encoded result invalid. Therefore,
assert no overflow occurred.

In particular, allow pad_len and whole_len to have value set to 0, which
means that no padding will be added. Previously a value set to 0 meant
that that the filter had to pad forever.
The new semantics is clearer, also simplifies scripting since the option
value might be automatically computed, so that no checks need to be done
in case it is 0.
The old semantics was never documented and the logic was broken (the
filter was always adding samples indefinitely), so this should not break
backward compatibility.
With huge sampling rates, the table derivation method does not converge fast
enough. While fixing it using e.g. Newton-Rhapson-like methods (the curve is
nicely convex) is possible, it is much simpler to reject these cases.
The value of 96000 was arbitrarily chosen as a realistic value, though
1000000 would still work and converge.
Fixes ticket #3868.

The messages regarding the recommended use of bitstream filters are somewhat different.
This also adds the ":v" stream specifier to "-bsf h264_mp4toannexb".

The allocation didn't account for headers, that can be easily 79 bytes.
As a result, buffers allocated for a few samples (e.g. 5 in the original
bug) could be undersized.
Fixed ticket #2881.
