Add mem_region utility functions

This commit introduces a new type (mem_region_t) used to describe
memory regions and it adds two utility functions:

	- clear_mem_regions: This function clears (write 0) to a set
		of regions described with an array of mem_region_t.

	- mem_region_in_array_chk This function checks if a
		region is covered by some of the regions described
		with an array of mem_region_t.
