Fixes most of glitches for non live streams, especially on
quality change.

CTTS value can be negative on version 0, and match the not found
return value used in GetPTSDelta.
ex: Sintel Smooth Streaming sample

The input stream id is completely unrelated to the input
sample buffer index - the sample allocated in AllocateInputSample
contains one single media buffer, at index 0.

LeafDemuxer fixes (the experimental data-sequence driven
fragmented mp4 demux).

Some muxers are interleaving using single trun/fragments,
Moov()->Moov(A)->Moof(B)
instead of interlacing truns withing fragments.
Moov()->Moof(A,B)->Moof(A,B)
Example: BigBuckBunny ismv file

Another problem is that data isn't interleaved at all
at end of tracks, and there's a long trailing gap of
audio fragments only.
Moov()->Moov(A)->Moof(B)->Moof(B)->Moof(B)->Moof(B)

Only the type is useful here. The other parameters are the same for
all video outputs (i.e. copied from vd->cfg), and should already have
been taken care of when the window was created.

(no functional change)

Even though that pragma is standard C99, MSVC doesn't understand it.
