Rip out all the needless MAC address and date/time leakage. No more
uuid_init necessary, nor contention over a global uuid state.
While here, simplify uuid_snprintf and fix a strict aliasing
violation.
it is fully initialised. It may be on the specnode list before it is
fully initialised and revoking it then would panic.
Should prevent the panic from PR kern/49171 (panic when closing a pty).

For those platforms without sub-word CAS, you can use these to place the
mutex lock and ipl inside a full machine word and use CAS to update them.
it to all kernel configs that contain "options MODULAR". This
option turns on module autoloading by default (which is the current
default). This allows people who don't want module autoloading on
by default to disable it by simply removing/commentting this line.
was: attach route domain if found from domains link set
now: attach any domain which is found from domains link set
No functional change to monolithic kernel. In a rump kernel, which
attaches networking domains "modularly", prevents domains from
accidentally leaking in via the link set in static linked scenarios.
Problem reported by cube, Tom Bousso, and the voices in my head.
replaced by the make option COPY_SYMTAB set to any value. The copy of
the symbol table is no longer put into a buffer in kern_ksyms.o, but a
small helper object. This object is build first with a dummy size, then
the kernel is linked to compute the real dimension of the symbol table
buffer. After that, the helper object is rebuild and the kernel linked
again.
if we're not going to use the result anyway.
XXX: not necessarily the best fix, but better than crashing *early*
boot due to too-early nanotime() calls.
XXX: pullup.
This caused recursion on rndpool_mtx when called from an rndsource's
callback.
XXX The old and new code here is a minefield demanding another
rototill.
XXX rnd_source_anonymous was not actually used before, and still is
not used now, to be cleaned up later.
the moment, this can only load very simple modules due to missing
symbols. It is being add at this time to make pullups to the
netbsd-7 branch easier. It is not enabled by default in any kernels.

Unfortunately we need d_discard in both since we need to be able to
discard from both the block and character forms of disks. I'm
increasingly thinking it would be better to restructure the ops
dispatching so each type of device (ttys, disks, tapes, etc.) has its
own function table. Then we wouldn't need to change every tty driver
to add a disk op.
