The channel layout at the demuxer layer is commonly wrong and would
otherwise be used.

Parse expression only when a new value is explicitly specified.

In particular, avoid double free in case an old expression value is
cached, it is set in the context, it is freed as the old value, and
finally the pointer stored in the context is freed again when the filter
is released.

Should fix tests with --enable-small.

The option is mostly useful to make ffprobe output independent from the
build, and in particular to fix FATE --enable-small failures.

Fix Ticket #1617, revealing a regression I introduced in 8f3eebd6.

We need to make sure no stream is added in between Ogg context save and
restore operations (because it would likely lead to a mismatch between
ogg->nstreams and AVFormatContext->nb_streams after the restore op).
This is the reason the ogg->state check is added in ogg_new_stream().
Before this patch, checking for ogg->headers was preventing this:
ogg->headers is always set before any ogg save/restore (though, it was
also preventing from creating the stream when necessary).

Not all applications (e.g. MPlayer) set block_align, and
when using a different demuxer it might not even be
easily available.
So fall back to selecting mode based on bit rate as before
if block_align has not useful value.
It can't be worse than failing to decode completely.

(cherry picked from commit 1d0d6305)

Fix possible crash when long_name is not defined (for example if
--enable-small).

Possibly safer.

Previously when saturation was reinited, the old value was freed when
setting options, and freed again in PARSE_EXPRESSION().

Avoid possible segmentation fault if codec_long_name is defined as
NULL (for example if --enable-small).

Fixes bug 372.
