This removes the current API violating behavior of overwritting the stream's
extradata during packet filtering, something that should not happen after the
av_bsf_init() call.
The bitstream filter generated extradata is no longer available during
write_header(), and as such not usable with non seekable output. The FATE
tests are updated to reflect this.

This complex (-1 2 6 2 -1) filter slightly less reduces interlace 'twitter' but better retain detail and subjective sharpness impression compared to the linear (1 2 1) filter.

Add an option to webm_dash_manifest demuxer to specify a value for
"bandwidth" field in the DASH manifest. The value is then used by
the muxer. Fixes an existing FIXME in the code.

except filter_length == 1
odd filter_length gives worse frequency response,
even when compared with shorter filter_length
also makes build_filter simpler

The Chen-Shapiro(CS) test was used to test normality for
Lagged Fibonacci PRNG.
Normality Hypothesis Test:
The null hypothesis formally tests if the population
the sample represents is normally-distributed. For
CS, when the normality hypothesis is True, the
distribution of QH will have a mean close to 1.
Information on CS can be found here:

This treats the case of no slices like no frames which it basically is.
The field is added to the context as other nal related fields are also there
and passing the has_slices field per *arguments is ugly and not consistent

When building DLLs with MSVC, CONFIG_STATIC is disabled (see
d66c52c2b3 for a more verbose explanation) since the built
object files can't be linked statically (which checkasm does).
This worked up until recently, only by luck.

Additional/Modified FATE tests improve code coverage from 63.7% to 98.1%.
Changed fate-suite sample files:
* filter/hdcd-mix.flac (958K) added. It is a much better test than
filter/hdcd.flac (910K), which is now unused, but can't be removed.
* filter/hdcd-fake20bit.flac (168K) added. It is the first second of
filter/hdcd.flac, with the 16-bit LSB copied into bit 20 of a 24-bit
stream. There isn't an actual non-16-bit HDCD sample available to test.
