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.

Also convert a debug av_log() to av_dlog().

The only remaining floats are in the user interface, they are left as they
should not cause a problem in practice

This avoids an unused variable warning with MSVC since the variable is
only used in a debug mode printf statement.

Fix a segfault with large window size.

The framework can ensure that each input frame has exactly
the correct number of samples, except the last one.

It is always identical to the last pushed frame.
The samples in the last incomplete window were ignored,
this is unchanged.
Possible enhancement: pad the last incomplete window with
silence.

No change in the generated asm.

This makes the code about 1.5x faster without any noticeable difference
in the output.

This has no impact on overall performance, since the block DCT taking
most of the time anyway.
