5150dd532b matroska: move LFG state from muxer context to local variable 
The LFG is only used in one place, so there is no need to keep it in
the context.

ac9baa716b matroskaenc: Mux clusters better 
Start them on keyframes when reasonable, and delay writing audio packets
to help ensure that there's audio samples available for the first frame in
clusters.

7bb83d8ddf matroskaenc: Write codec time base as default duration for video tracks. 
This isn't exactly semantically equivalent, but the field has already been
long abused to mean this, and writing it helps in determining a decent cfr
time base when transcoding from a mkv where the video codec stores none (VP8).

2529bb3019 Attempt seeking to write EBML master sizes even if streamed 
Most EBML masters are much smaller than IO_BUFFER_SIZE and thus the size
can be updated. This makes parsing the resulting files easier.

5f8bae8d5c matroskaenc: correctly handle h264 streams with 3 bytes nal startcodes 
This implies using ff_avc_parse_nal_units_buf instead of ff_avc_parse_nal_units
because with 3 bytes startcodes the parsed packet size will change, and the
size must be written before the packet content.

bc5c918ea8 Remove offset_t typedef and use int64_t directly instead. 
The name offset_t is easily confused with the standard off_t type and
*_t is POSIX reserved namespace if any POSIX header is included.
