Richard Henderson 28b61d49ac bsd-user: Allocate guest virtual address space ...

With reserved_va, mmap.c expects to have pre-allocated host address
space for the entire guest address space.  When combined with the -B
command-line option, ensure that the chosen address does not overlap
anything else.  Ensure that mmap_next_start is within reserved_va,
as we use it within mmap.c without checking.
