Split out the blob allocator from lib.c into allocate.c.

It's disgusting how intimate lib.c is with all the types,
and this is slowly trying to split things up a bit. Now
the intimate part is in allocate.c, but maybe we can get
to the point where each allocation user just declares its
own allocation strategy, and just uses the generic routines
in allocate.c
