o Add comment about missing restrict type-qualifiers.
o Move vscanf(), vsscanf() and vfscanf() to the C99-visible block.
o Add note about missing backing function for vfscanf().
o Restrict L_cuserid to only older versions of POSIX, and BSD
namespaces.
o Conditionalize some BSD-specific foo_unlock() macros.

'-p' is used on the reboot(8) command line.
This is intended for use when you want to attempt a power down
action, but you want the system to reboot (not halt) if the
power down action fails.
This is typically useful when the power-off action performed by
the kernel consists in signalling an uninterrupted power supply
that it should shut down its inverter if mains power has not returned.
The behaviour of shutdown(8) and init(8) is not modified;
only the behaviour of invoking 'reboot -p' manually is
modified, and then only in the case when a power-down action
fails.

for the ability of a process to send and receive data via a socket.
At some point, we might also pass in additional address information
if an explicit address is requested on send.

and getipnodeby*() thread-safe.
Our res_*() is not thread-safe. So, we share lock between
getaddrinfo() and getipnodeby*(). Still, we cannot use
getaddrinfo() and getipnodeby*() in conjunction with other
functions which call res_*().

commands. Commands like "if then ... fi" and "while do ... done" are no
longer accepted. Bodies of compound commands are still allowed to be
empty, because even though POSIX does not allow them, most shells do.
Instead use %ju and cast the argument.
WFORMAT=0 is still required in the Makefile because gcc warns about
some strftime() calls (I don't think this behaviour is useful.)

mac_check_vnode_mprotect() Check at mapping protection change
mac_check_vnode_mmap_downgrade() Determine if a mapping downgrade
should take place following
subject relabel.
Implement mmap() and mprotect() entry points for labeled vnode
policies. These entry points are currently not hooked up to the
VM system in the base tree. These changes improve the consistency
of the access control interface and offer more flexibility regarding
limiting access to vnode mmaping.

flags so that we can call malloc with M_NOWAIT if necessary, avoiding
potential sleeps while holding mutexes in the TCP syncache code.
Similar to the existing support for mbuf label allocation: if we can't
allocate all the necessary label store in each policy, we back out
the label allocation and fail the socket creation. Sync from MAC tree.

to mbuf label initialization, that functionality was never merged to
the main tree. Go ahead and merge that functionality now. Note that
this requires policy modules to accept the case where the label
element may be destroyed even if init has not succeeded on it (in
the event that policy failed the init). This will shortly also
apply to sockets.
