Should fix out-of-sync tracks with DASH

DemuxFrg was no longer selected

Prevented playback of blockalign less audio samples

p_chunk->i_sample is next sample, not current

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

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)

Moov fragment has full length after fixup, but zero data.
Fixes 0 position on ismv seek

VLC supports groups where mp4 defines switch groups.
As an es can't belong to multiple groups, but does in
switch groups, we don't really have a way to provide
the same track exclusion/alternative features without
duplicating es.

Priorities are then set in a way es/tracks from the same
cat/switchgroup are not all selected.

Follow the spec and correctly handle text encoding

And fix reading

Split es setup so we only call dedicated setup per handler.
