The call to the next filter_sample will likely unref the
current buffer, so it is not possible to read it afterwards.

If the designated protocol is not found, return
AVERROR_PROTOCOL_NOT_FOUND instead of AVERROR(ENOENT).

Also add internal function ff_null_start_frame_keep_ref().

Fix crash when a following filter (e.g. settb) will unref the reference
passed by start_frame(), and then the reference is accessed in
end_frame() through inlink->cur_buf.

Based on my MicroDVD->ASS conversion code from MPlayer
(sub/subassconvert.c).

This fixes crashes, where the demuxer could return 0 even
if the returned AVPacket isn't initialized at all. This
could happen if running into EOF or running out of probesize
with non-seekable sources.

putenv() seems to be more portable.

Ignoring all files that start with the name of a library matches some
files that are not generated.  So replace libfoo/libfoo* with patterns
for static and shared libraries, pkg-config and version files.

Omitting the seconds has not worked for a long time, if ever.
Omitting the minutes too is just nonsensical for a duration
(it is indistinguishable from just seconds).
