also known as C-states. The code is modular and provides an easy way to add
the remaining functionality later (namely throttling and P-states).
Remarks:
1. Commented out in the GENERICs; more testing exposure is needed.
2. The C3-state is disabled for the time being because it turns off
timers, among them the local APIC timer. This may not be universally
true on all x86 processors; define ACPICPU_ENABLE_C3 to test.
3. The algorithm used to choose a power state may need tuning. When
evaluating the appropriate state, the implementation uses the
previous sleep time as an indicator. Additional hints would include
for example the system load.
Also bus master activity is evaluated when choosing a state. The
usb(4) stack is notorious for such activity even when unused.
Typically it must be disabled in order to reach the C3-state,
but it may also prevent the use of C2.
4. While no extensive empirical measurements have been carried out, the
power savings are somewhere between 1-2 W with C1 and C2, depending
on the processor, firmware, and load. With C3 even up to 4 W can be
saved. The less something ticks, the more power is saved.

No comments on this last version.
we're ELF now, and there are many missing checks against OBJECT_FMT.
if we ever consider switching, the we can figure out what new ones
we need but for now it's just clutter.
this doesn't remove any of the support for exec_aout or any actually
required-for-boot a.out support, only the ability to build a netbsd
release in a.out format. ie, most of this code has been dead for
over a decade.
i've tested builds on vax, amd64, i386, mac68k, macppc, sparc, atari,
amiga, shark, cats, dreamcast, landisk, mmeye and x68k. this covers
the 5 MACHINE_ARCH's affected, and all the other arch code touched.
it also includes some actual run-time testing of sparc, i386 and
shark, and i performed binary comparison upon amiga and x68k as well.
some minor details relevant:
- move shlib.[ch] from ld.aout_so into ldconfig proper, and cut them
down to only the parts ldconfig needs
- remove various unused source files
- switch amiga bootblocks to using elf2bb.h instead of aout2bb.h
Rename real routines to proc_find() and pgrp_find(), remove PFIND_* flags
and have consistent behaviour. Provide proc_find_raw() for special cases.
Fix memory leak in sysctl_proc_corename().
COMPAT_LINUX: rework ptrace() locking, minimise differences between
different versions per-arch.
Note: while this change adds some formal cosmetics for COMPAT_DARWIN and
COMPAT_IRIX - locking there is utterly broken (for ages).
Fixes PR/43176.

Noticed by martin@.
Establish interrupt handlers with proper softc per each zs device
rather than sharing them among all zs devices and searching softc
in handlers, to avoid possible recursive lock.

The latter method is derived from ancient sun3 zs driver which tried
to reduce overhead on autovectored interrupts, but nowadays such hack
might cause recursive global locks on modern SMP capable framework.

and use it for large delays (in seconds) instead of delay() that uses
INT 15h/AH=86h (WAIT) in microsecond because the latter one can't provide
precise delays on emulators.

Should fix PR port-mips/43431.
CPU_CORTEXA8 everywhere since there more types of Cortex than just the A8.
CPU_CORTEXA8 still exists but causes CPU_CORTEX to be defined.
Add CPU_CORTEXA9 as well. Use .arch armv7a to get us the isb/dsb

yet determined, some PCI devices (at least fxp(4) and re(4)) sometimes
appear to perform DMA operations while this is happening, and we get
uncorrectable DMA errors. ideally, this "shouldn't happen", but none
of the investigation so far has reveal the problem, and my source
investigation of both opensolaris and linux show that their perform
the invaliation when unmapping.

OK mrg@
Set proper IPL_SOFTfoo values even in !FAST_SOFTINTS case.
Some assertions in MI code expect they have unique values,
per comments from rmind@.
Also cleanup various "interrupt hierarchy" code since IPL_NONE and
IPL_SOFTfoo should not be set by any hardware interrupt establish functions.
Ok'ed by mrg@, tested on shark and hpcarm.
2. unfortunately hppa's MB_LEN_MAX is defined incorrectly 6 instead of 32
so we have to add more setlocale(3) __RENAME func, __setlocale50.
3. move setlocale1.c and setlocale32.c to lib/libc/compat/locale/*
prepareing for next libc major crunk.
4. bump libc minor version.
