Create a new header lwp_private.h to contain _lwp_getprivate_fast,
_lwp_gettcb_fast, _lwp_settcb and remove them from mcontext.h, so that:
1. we don't need special hacks to hide them
2. we can include <lwp.h> where needed to get the necessary prototypes
without redefining them locally.

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.

Revert the CLOCK_FORMAT0 work-around.

Use proper clockframe size for those platforms that require it.

XXX This is a tempory measure, better to fix clock interrupts to take the
common clockframe size.

OK thorpej@.

Largely unify the <machine/cpu.h> headers on the m68k platforms.

Consistently use "intr_depth" as the name of the interrupt depth counter
on m68k platforms.

Make the M68K_MMU_* defines real kernel options, available in opt_m68k_arch.h.
For 68030, 68040, and 68060, infer M68K_MMU_MOTOROLA. For 68010 and 68020, it
must be an explicit option (set in std.${MACHINE} or, in the case of hp300,
inferred from the specific model option).

This platform does not have a loadustp() function.

cpu_need_resched():

- Remove all code that should be MI, leaving the bare minimum under arch/.
- Make the required actions very explicit.
- Pass in LWP pointer for convenience.
- When a trap is required on another CPU, have the IPI set it locally.
- Expunge cpu_did_resched().

- Cleanup for dynamic sysctl:
- Remove unused *_NAMES macros for sysctl.
- Remove unused *_MAXID for sysctls.
- Move CTL_MACHDEP sysctl definitions for m68k into m68k/include/cpu.h and
use them on all m68k machines.

Cleanup and clarify the ELFSIZE mess:

We now have 2 variables automatically set in elf_machdep.h:

ARCH_ELFSIZE: the size for userland binaries
KERN_ELFSIZE: the size for the kernel binaries

DB_ELFSIZE has been deleted and KERN_ELFSIZE should have always the
same values DB_ELFSIZE used to have.

In sys/exec_elf.h, if ELFSIZE is not set, it is set to KERN_ELFSIZE
for the kernel and ARCH_ELFSIZE for userland. These defaults should
eliminate the need for most manual ELFSIZE setting.
