This assert is no longer true since h264 error concealment needs
last_picture_ptr to be set.

The previous method of having to initialize it outside lead
to incorrect code: even if it was initialized, it usually was
only initialized once, thus a packet that could not be matched
to any stream would just be processed with the return values
from the previous call.

We're now running some of this code through valgrind for the first
time, and a few warnings showed up stemming from two problems.

1) The ASS code assumes the subtitle header is null terminated, but
it wasn't, and passing the size down doesn't look like fun, so I
added a terminator

2) The code wasn't freeing all of its state.

This patch implements support reading ALAC from Matroska files. The
only non-trivial thing about it is that only the ALAC magic cookie is
stored in Matroska's CodecPrivate element but not the "atom size",
"tag" and "tag version" fields that FFMPEG's ALAC decoder
expects. However, those are trivial to re-create.

Sample files are available:
http://www.bunkus.org/videotools/mkvtoolnix/samples/alac/alac-in-matroska.mka
and the CoreAudio file it was created from with today's mkvmerge:

Running lib.exe without parameters will always result in an error,
and failing the check.
Using the -list paramter results in a success if lib.exe is present.

Fixes crash based on a uninitialized array index read.
If the read does not crash then out of array writes based
on the same index might have been triggered afterwards.
