[NUT-devel] Change flag bits

[Oded Shimon]

Any objection to this patch? It makes it somewhat easier/nicer to move over 
the stream flags to API, and keep the nut flags in the demuxer...

Also, 128 is low enough for the flags which have no use to be coded in 
frame header, because vlc's can only store up to 127 in a single byte.

Also, the non-stream flags are pushed to top of first byte so they can 
expand towards down while stream flags expand toward up...

(I know, this is all very silly, but I see no reason against any of this, 
the decision between this is almost arbitrary, so might as well go with the 
more convinient direction?)
