There are two related changes.

The first one is an mquery(2) syscall. It's for asking the VM system
about where to map things. It will be used by ld.so, read the man page
for details.

The second change is related and is a centralization of uvm_map hint
that all callers of uvm_map calculated. This will allow us to adjust
this hint on architectures that have segments for non-exec mappings.
