53cfef3e0f asfdemux: Ignore parsing errors from broken packets
We should instead be counting the number of errors and exiting if
they're too numerous. This makes a number of broken ASF files playable.

3064bf4a86 asfdemux: fix performance issue, especially with high-bitrate streams
Two things were suboptimal from a performance point of view:

a) consider a large media object such as a video keyframe, which
   may be split up into multiple fragments. We would assemble
   the media object as follows:
     buf = join (join (join (frag1, frag2), frag3), frag4)
   which causes many unnecessary memcpy()s, and malloc/free,
   which could easily add up to a multiple of the actual object
   size. To avoid this, we allocate a buffer of the size needed
   from the start and copy fragments into that directly.

b) for every fragment to join, we would create a sub-buffer
   before joining it (which would discard the sub-buffer again),
   leading to unnecessary miniobject create/free churn.

0bc76c0d03 asfpacket: fix 0.11 ported payload extraction
... to cater for not necessarily offset == size - cur_pos,
as size may have been adjusted due to padding.

Fixes #667567.

61c00741a2 asf: Detect more payload extensions.
These should help fix interlaced/PAR issues with more files.

New packet parsing code: should put halfway decent timestamps on
buffers, and might even set the appropriate keyframe/discont buffer
flags from time to time (and even if it doesn't, I'm at least able
to debug this code); only used in pull-mode so far. Still needs
some more work, like payload extensions parsing and proper flow
aggregation, and stream activation based on preroll. Stay tuned.
