Modify the parser initialization so that parsers can
set pict_type themselves.  Use this in the mpegvideo parser
so that initial frames are not unconditionally I frames.
I have had this in my tree for several years.

OutputStream.picref is guaranteed to be non-NULL if
get_filtered_video_frame() succeeds.

output_video_filter is always guaranteed to be set and is in fact
dereferenced right above the check.

Note, this doesnt break compatibility with libav, as libav
has implemented a incompatible and more limited system under the same
-cpuflags command line option we used since some time.

The differences to libav for example are we can do things like
ffmpeg -cpuflags -sse+mmx -cpuflags +3dnow
Its also possible in our system to force flags that have not been
detected as available
And our -cpuflags works with all tools not just 1

matroskaenc: change cluster_pos to use -1 as the "I'm not currently working on a cluster" signal instead of 0.

This avoids problems
where avio_tell() returns 0. I've updated all the checks against
cluster_pos

Progressive images can have only 16 references, error out if there are
more, since the data is almost certainly corrupt, and the invalid value
will lead to random crashes or invalid writes later on.

Interlaced images can have 32 references (16 per field), so limiting the
array size to 16 leads to invalid writes.
