Based on current version of the asplit filter in FFmpeg written by
Stefano Sabatini and others.

This is in preparation for adding an audio split filter.

libnut is unmaintained and known to be buggy; native NUT code exists.

FATE_SAMPLES is now used directly by the Makefiles, which induces the test
system to run a test with the value of the environment variable as name.
Renaming the environment variable to LIBAV_SAMPLES avoids this problem.

libavcodec/utils.c:251: note: expected ‘const uint8_t *’ but argument is of type ‘const short int *’

The encode/decode tests should all depend on avconv.  Since
avconv requires libavfilter, there is no need to enable those
tests selectively.

In hybrid frames long window part ends at 36 samples for most of the cases
but at 72 for 8kHz case. For some reason decoder assumed it's 48 or even 36
samples, which caused wrong bitstream decoding for such blocks.

l3_25207.mpg from conformance suite demonstrates it the best.

This is consistent with other format names.

avconv now requires libavfilter so this dependency is redundant.

Invented timestamps for the h264 tests return to something resembling
sanity.

In the idroq-video-encode test when converting 25 fps -> 30 fps the
fifth frame gets duplicated instead of the sixth.

This makes lavf discard broken timestamps for non-B frames in
samples/isom/vc1-wmapro.ism.

Partially based on a patch by Robert Nagy <ronag89@gmail.com>

If using the new -rtmp_app and -rtmp_playpath parameters,
one can in many cases set the main url to just rtmp://server/.
If the trailing slash is omitted, path is a string of zero length,
and using path+1 will end up reading uninitialized data.

Don't return from poll_filters() immediately, there may be other frames
and/or other streams to handle.

This is easier to parse with automated tools.

This applies the same fix as in ed7409fe for lavf-regressions.sh.

On some systems, the wc command prints spaces before the first
number causing mismatches with the test references.  Using the
output of wc as arguments to echo removes any extra whitespace.
