Make ff_parse_channel_layout() accept unknown layouts too.

A list of "all channel layouts" but not "all channel counts"
can not be reduced to a single unknown channel count.

Format selection can fail if unknown channel layouts are used
with filters that do not support it.

Fix trac ticket #3110.

Don't trust provided streams.
Return with error when stream count is not 1 or
provided stream is not an audio stream.

Current implementation didn't include duration of
last processed packet.
Device may return negative timestamps without
this correction.
