Remove unnecessary <sys/malloc.h>.

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.

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.

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.
