or user vm_maps. This implementation has two key benefits when compared
to vm_map_{user_,}pageable(): (1) it avoids a race condition through
the use of "in-transition" vm_map entries and (2) it eliminates lock
recursion on the vm_map.
Note: there is still an error case that requires clean up.

instead, add typedefs of only gid_t, time_t, and uid_t.
o Remove an unneeded conditional that hid macros that are in the
implementation namespace and therefore don't need to be hidden when
_POSIX_SOURCE is defined.
o Adjust some conditionals for compatibility with X/Open and POSIX.
o Note missing functions getpwnam_r() and getpwuid_r().

In fact, these variable are set as environment variables since we run
"make TARGET=xxx TARGET_ARCH=xxx"; TARGET and TARGET_ARCH are declared
in the command line arguments. However, if you are not make(1) guy,
it is hard to understand that TARGET/TARGET_ARCH are appropriately set
in a chroot environment (as environment variables).
Now, the only environment variable need to be set explicitly is 'PATH'.
If we set PATH in /mk script, we can make pristine sandbox for release
build (i.e., "env -i /usr/sbin/chroot ${CHROOT} /mk" will work).

or user vm_maps. In accordance with the standards for munlock(2),
and in contrast to vm_map_user_pageable(), this implementation does not
allow holes in the specified region. This implementation uses the
"in transition" flag described below.
o Introduce a new flag, "in transition," to the vm_map_entry.
Eventually, vm_map_delete() and vm_map_simplify_entry() will respect
this flag by deallocating in-transition vm_map_entrys, allowing
the vm_map lock to be safely released in vm_map_unwire() and (the
forthcoming) vm_map_wire().
o Modify vm_map_simplify_entry() to respect the in-transition flag.
