[PATCH 3/6] libmm-libbsp-shared. Files shared between all target BSPs and low-level implementations for libmm. These shared files contain mm.h which is a link between high-level score api and low-level implemenation of libmm. mm.h contains function declarations which should be implemented by target BSP to support libmm. no_memorymanagement.c contains stubs for BSPs that do not support libmm.

Should begin/end be uintptr_t? This structure appears to be unused
here, so perhaps it should be left out?
