Make the usermode kernel compile again.

Overhaul the API used to fetch and store individual memory cells in
userspace. The old fetch(9) and store(9) APIs (fubyte(), fuword(),
subyte(), suword(), etc.) are retired and replaced with new ufetch(9)
and ustore(9) APIs that can return proper error codes, etc. and are
implemented consistently across all platforms. The interrupt-safe
variants are no longer supported (and several of the existing attempts
at fuswintr(), etc. were buggy and not actually interrupt-safe).

Also augmement the ucas(9) API, making it consistently available on
all plaforms, supporting uniprocessor and multiprocessor systems, even
those that do not have CAS or LL/SC primitives.

Welcome to NetBSD 8.99.37.

branches: 1.14.2;
Fix compilation errors so NetBSD/usermode compiles under ./build.sh

Implement cpu_lwp_setprivate(). This removes the need for the cpu_switch()
hack.

Programs with TLS work fine now, including gdb!

branches: 1.12.12;
provide __HAVE_COMPAT_NETBSD32 and fix multiple include protection consistently.

branches: 1.11.2; 1.11.4;
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.

branches: 1.8.6; 1.8.24;
Fix /dev/kmem access and make vmstat(1) `work'. Not sure all the results are
indeed valid or correct but at least it shows them without coredumping or
coredumping the kernel.

define __HAVE_OLD_DISKLABEL on i386

branches: 1.6.12; 1.6.16;
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.

Drop 3rd and 4th clauses. OK jmcneill (copyright holder).

branches: 1.4.2; 1.4.4; 1.4.14;
Now that __HAVE_TIMECOUNTER and __HAVE_GENERIC_TODR are invariants,
remove the conditionals and the code associated with the undef case.

branches: 1.3.2;
Use gettimeofday as timecounter.

branches: 1.2.2;
Fix enough to get i386 more-or-less compiling. The i386 needs u_long to be
an unsigned long too or uvm will complain.

Import work-in-progress NetBSD/usermode port.
