buflib: add a common dummy callbacks struct & use it

Browse source 
There are various allocations that can't be moved or shrunk.
Provide a global callback struct for this use case instead of
making each caller declare its own dummy struct.

Also fixed ROLO and x1000 installer code which incorrectly
used movable allocations.
