dcd207c4cb matroskadec: use av_grow_packet in merge_packets.
It ensures that the packet is properly padded
and makes the code simpler.

Fixes trac ticket #1223.

1a65d50ee7 mem.c: fix wrong comment.
Overwriting the av_malloc etc. functions is not easily
possible anymore, even for systems that support overriding
symbols in shared libraries in principle.

4a95876f4d Add skip_to_keyframe stream variable.
This replaces the matroskadec one with the same name.
The advantage is not only easier reuse in other demuxers
but also that we can make the decisions after the parser.
This fixes seeking in files that mark the keyframes incorrectly,
for example the file in track ticket #1003.
The matroska variable is still kept to be able to complain
about such broken files.
