Extend uvm_map_hint() to get an address range as extra arguments, and make
sure it will return an address within that range.
Use this in uaddr_rnd_select() to make sure we will not attempt to pick
an address beyond what we are allowed to map.
In my trees for 9 months, blackmailed s2k15 attendees into agreeing now would
be a good time to commit.
