There is alignment support for AddressAllocator but there are occations
that the alignment is known only when we call allocate(). One example
is PCI BAR which is natually aligned, means for which we have to align
the base address to its size.

We can only free ranges that exactly map an already allocated one, i.e.
this is not a range resizing.

This is based on the crosvm resource allocator from commit 107edb3e.
We only have PIO and MMIO address space to handle, and don't have a GPU
specific path and space.
Also, we support allocating a range at a specified address. This is
mostly useful for PIO, but might be also necessary for MMIO.
