Remove the kernel PMC code. Sent yesterday on tech-kern@.

This change:

* Removes "options PERFCTRS", the associated includes, and the associated
ifdefs. In doing so, it removes several XXXSMPs in the MI code, which is
good.

* Removes the PMC code of ARM XSCALE.

* Removes all the pmc.h files. They were all empty, except for ARM XSCALE.

* Reorders the x86 PMC code not to rely on the legacy pmc.h file. The
definitions are put in sysarch.h.

* Removes the kern/sys_pmc.c file, and along with it, the sys_pmc_control
and sys_pmc_get_info syscalls. They are marked as OBSOL in kern,
netbsd32 and rump.

* Removes the pmc_evid_t and pmc_ctr_t types.

* Removes all the associated man pages. The sets are marked as obsolete.

expose the kernel types for standalone code.

Hide {p,v}{addr,size}_t and register_t (and a couple more types that
are machine-specific) from userland unless _KERNEL/_KMEMUSER and a
new _KERNTYPES variables is defined. The _KERNTYPES should be fixed
for many subsystems that should not be using it (rump)...

Fix PTHREAD_FOO_INITIALIZER for C++ by not using volatile in the relevant
pthread types in C++ builds, attempt 2.

The problem with attempt 1 was making assumptions of what the MD
__cpu_simple_lock_t (declared volatile) looks like. To get a same type
except non-volatile, we change the MD type to __cpu_simple_lock_nv_t
and typedef __cpu_simple_lock_t as a volatile __cpu_simple_lock_nv_t.
IMO, __cpu_simple_lock_t should not be volatile at all, but changing it
now is too risky.

Fixes at least Rumprun w/ gcc 5.1/5.2. Furthermore, the mpd application
(and possibly others) will no longer require NetBSD-specific patches.

Tested: build.sh for i386, Rumprun for x86_64 w/ gcc 5.2.

Based on the patch from Christos in lib/49989.

Install headers needed for userland build.
Add missing accessors for pthread and TLS support - just dummies for now.

fix build errors with gcc 4.5.

Add PRIx{P,V}{ADDR,SIZE}, PRIu{P,V}SIZE, and PRIxREGISTER{,32,64} for all
(except where they will be added via merge). These should be used to print
{p,v}{addr,size}_t and register*_t as appropriate.

Initial import of arch/ia64 sources.
These sources are ported from FreeBSD/ia64 code.
See individual source files for credits.
In addition, code from NetBSD/alpha NetBSD/sparc64,
NetBSD/i386 and NetBSD/amd64 were used as templates,
along with my own additions.
