lmb: make LMB memory map persistent and global

The current LMB API's for allocating and reserving memory use a
per-caller based memory view. Memory allocated by a caller can then be
overwritten by another caller. Make these allocations and reservations
persistent using the alloced list data structure.

Two alloced lists are declared -- one for the available(free) memory,
and one for the used memory. Once full, the list can then be extended
at runtime.
