This adds two new functions, lmb_alloc_addr and
lmb_get_unreserved_size.
lmb_alloc_addr behaves like lmb_alloc, but it tries to allocate a
pre-specified address range. Unlike lmb_reserve, this address range
must be inside one of the memory ranges that has been set up with
lmb_add.
lmb_get_unreserved_size returns the number of bytes that can be
used up to the next reserved region or the end of valid ram. This
can be 0 if the address passed is reserved.
Added test for these new functions.

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.

The lmb code fails if base + size of RAM overflows to zero.
Fix this by calculating end as 'base + size - 1' instead of 'base + size'
where appropriate.
Added tests to assert this is fixed.

One of the hexdump tests in test/lib/hexdump.c returns right at the
start of the function without testing anything.
Fix this by moving the 'return 0;' statement to the end of the function.
