Hmm, would definitely be good if we could concentrate on the completely new 
functionality - e.g. en50221 stuff instead of having to write lots of 
plumbing ourselves....

Some bits we can ignore - the dvbchan_* and dvbfe_* stuff is already 
superceded by libdvbcfg. Or else I'm planning on rewriting it anyway.

There does seem to be a lot of malloc()/relloc() ing going on in the SI stuff 
though... 

I kinda liked the callbacks idea for SI processing in libdvb2 - then you just 
process what you need and the rest is ignored. dvbsak appears to 
process/malloc everything then pass the structures back to the user.

Looks as though it may be thread safe though - list additions/deletions are 
surrounded by mutexes.
