Make malloc more extensible. The malloc type is now a pointer to
the struct kmemstats that describes the type. This allows subsystems to declare their malloc types locally and <sys/malloc.h> doesn't need tweaked everytime somebody gets an idea. You can even have a type local to a lkm... I don't know if we really need the longdesc, comments welcome. TODO: There is a single nit in ext2fs, that will be fixed later, and I intend to remove all unused malloc types and distribute the rest closer to their use.
