lmb_add_region handles overlapping regions wrong: instead of merging or rejecting to add a new reserved region that overlaps an existing one, it just adds the new region.
Since internally the same function is used for lmb_alloc, change lmb_add_region to reject overlapping regions.
Also, to keep reserved memory correct after 'free', reserved entries created by allocating memory must not set their size to a multiple of alignment but to the original size. This ensures the reserved region is completely removed when the caller calls 'lmb_free', as this one takes the same size as passed to 'lmb_alloc' etc.
Add test to assert this.
