vax: Use device_set_private.

Fix false sharing problems with cpu_info. Identified with tprof(8).
This was a very nice win in my tests on a 48 CPU box.

- Reorganise cpu_data slightly according to usage.
- Put cpu_onproc into struct cpu_info alongside ci_curlwp (now is ci_onproc).
- On x86, put some items in their own cache lines according to usage, like
the IPI bitmask and ci_want_resched.

- Use lwp_getpcb() on VAX, clean from struct user usage.
- Include sys/user.h in MD proc.h .

Rototill the vax code. Switch to devicet/PRIV_ALLOC. Cleanup vax autoconf
code. Move to prototype definitions. staticfy, constify, avoid casting.
Use device_* accessors.

A number of performance changes:
Change internal register SSP to contain curlwp insread curcpu(). This
shrinks the GENERIC by 2KB.
Add rwlock stubs (rw_enter, rw_exit, rw_tryenter).
Simplify simple lock code for uniprocessors.
Do SPL raise/lower in cpu_handle_ipi instead of simple_locks.

branches: 1.11.20; 1.11.36; 1.11.40;
Kill caddr_t; there will be some MI fallout, but it will be fixed shortly.

branches: 1.10.2;
Count the number of CPUs at boot and stash in 'ncpu'. Eventually should
have each CPU register at attach, so we can figure out the topology for
the scheduler.

Fixes to make GENERIC.MP build again. Several changes:
o Rename global variable "tramp" to "vax_mp_tramp" to avoid warning
with -Wshadow when compiling the signal code.
o Rename a macro-local variable _s to __s in __cpu_simple_lock()
to avoid -Wshadow warning when MALLOC() is used (also declares _s).
o Follow up -Wcast-qual by making a number of function arguments const char*
where string literals are used.
