allocate_contiguous_memory_nomap returns an unsigned long yet it
was returning errno codes for various failures. Replace all negative
errno codes with 0, which is what all the callers expect on error anyway.

Remove the function prototype for the function
alloc_from_memory_pool() (this function was never implemented).
The function mem_type_to_memory_pool() was not intended to be
exported, so remove the export and function prototypes.

Add a generic library (which uses genalloc) that manages
pools of contiguous memory.
APIs are provided to allocate (and if desired map) and free
memory, as well to initialize a memory pool.
