Document via __HAVE_BUS_SPACE_8 platforms that implement bus_space_*_8

Fix previous; hide userland ABI details for kernel as suggested by joerg:

http://mail-index.netbsd.org/source-changes-d/2020/06/21/msg012745.html

- Revive __lwp_settcb(), and call _lwp_setprivate(2) from it.

- Keep l_private opaque pointer for kernel; store raw value of %r2 in it.
  In the previous commit message, I wrote,

http://mail-index.netbsd.org/source-changes/2020/06/21/msg118524.html

> - Make sure that, like other ports, l_private represents address of tcb,
>   not biased one as in %r2.

  but, it turned out to be wrong. mips stores a biased address, at least.
  It is userland responsibility to interpret returned values from
  lwp_getprivate(2).

Fix inconsistency b/w kernel and userland recognitions of TLS, as well as
inconsistency whether it is biased or not in kernel.

- Obsolete __lwp_settcb() in order to let kernel know new TLS address via
  _lwp_setprivate(2). Alternatively, we can call _lwp_setprivate(2) within
  __lwp_settcb() like mips, but it is just double handling; we adjust %r2
  appropriately in _lwp_setprivate(2) via cpu_lwp_setprivate().

- Make sure that, like other ports, l_private represents address of tcb,
  not biased one as in %r2. This guarantees that the returned values from
  _lwp_getprivate(2) and __lwp_getprivate_fast() are always same. Also,
  we can obsolete PTRACE_LWP_GETPRIVATE() macro.

Now, *_pl_private tests in tests/lib/libc/sys successfully pass, while
no other tests become newly falling.

Discard __HAVE_UNLOCKED_PMAP for 4xx; 4xx is uniprocessor architecture,
and everything gets more than 10 times slower by __HAVE_UNLOCKED_PMAP.

Note that we support three supervisor-level architectures for powerpc:
oea, booke, and 4xx. We have three different implementations of pmap as
a result. Whereas oea and booke support multiprocessor, 4xx does not.

Merge changes from current as of 20200406

Temporarily mark hppa, mips, powerpc and riscv with __HAVE_UNLOCKED_PMAP,
for the benefit of UVM.

These need some pmap changes to support concurrent faults on the same
object.  I have changes to do just that, but they're a work in progress.

revert this change from early this year.  it appears the
changes macallan@ commited to fix FIRMWORKSBUGS issues
in openfirmware() have fixed the hangs seen on PegasosII.

hooray!

Log Message:
workaround a problem with the pegasos firmware interface:
attempting to use /dev/openfirm on this machine hangs hard.

this isn't a new problem, and i've been meaning to try to
figure it out for years, but it's become a problem since
the xf86-video-radeon driver gained code to look for the
macppc model using this interface.

this is why xorg-server 1.18 and 1.20 hang recently on the
pegasosII.

this change is fairly ugly but i couldn't think of a less
ugly method to avoid /dev/openfirm working just on this
one platform.  introduce new __OPENFIRMIO_OPEN_CHECK_BROKEN
macro and associated __openfirmio_open_check_broken(), and
use them in the new openfirmopen() to fail opens.

include proplib.h in macppc and ofppc autoconf.h since they
use it.

Detangle some of the PowerPC CPU configuration spaghetti.

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.

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.

Allow storing and receiving the LWP private pointer via ucontext_t
on all platforms except VAX and IA64. Add fast access via register for
AMD64, i386 and SH3 ports. Use this fast access in libpthread to replace
the stack based pthread_self(). Implement skeleton support for Alpha,
HPPA, PowerPC, SPARC and SPARC64, but leave it disabled.

Ports that support this feature provide __HAVE____LWP_GETPRIVATE_FAST in
machine/types.h and a corresponding __lwp_getprivate_fast in
machine/mcontext.h.

This material is based upon work partially supported by
The NetBSD Foundation under a contract with Joerg Sonnenberger.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree.  Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches.  The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Add siginfo support for PowerPC.

Typo: __HAVE_BITENDIAN_BITOPS -> __HAVE_BIGENDIAN_BITOPS

Elimindate MD setrunqueue/remrunqueue (which were out-of-date compared to
the canonical versions in kern_synch.c).  Define __HAVE_BIGENDIAN_BITOPS
so the canonical versions will be used but will store priorities in the
desired (MSB) order for PowerPC (which allows the use of the cntlzw (count
leading zeroes, word) instruction in locore_subr.S to find the proper
priority).

Add a new feature-test macro, _NETBSD_SOURCE.  If this is defined
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.

This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
  can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
  various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
  !defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.

I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them.  In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.

Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

Nuke __BROKEN_INDIRECT_CONFIG

First step inn removing config_scan() and the hacks that gave devices
on indirect-config busses a (permanent) softc that they could share
between 'match' and 'attach' routines:

Define __BROKEN_INDIRECT_CONFIG so that old autoconfiguration
interfaces are used, until drivers are converted to use the new
interfaces (actually, converted back to use the _older_ interfaces)
which prohibit indirect configuration devices from receiving a softc
in their match routine that they can share with their attach routine.
