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.

distrib/sets/lists: Add a blank comment line between RCS id and body.

This serves as a buffer between RCS id changes and other changes to
the set lists, in an attempt to reduce the pain of merge conflicts
around mass set list changes.

No functional change intended.

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.

branches: 1.8.12; 1.8.14;
revert the previous - those are only relevant for 64 bit builds and
are listed in ad.mips with arch64 tag. fixes emips builds.

add libc_fp

branches: 1.6.2;
Add fenv.h for mips.

Sljit doesn't support MIPS I. Make sljitarch.h obsolete.

branches: 1.4.2;
Sort entries in strcmp order.

Add sljitarch.h to all mips machines.

branches: 1.2.2; 1.2.8;
Retire varargs.h support. Move machine/stdarg.h logic into MI
sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.

branches: 1.1.2;
Add support for the Extensible MIPS ("eMIPS") platform. The
NetBSD/emips port runs on Xilinx and Beecube FPGA systems and the
Giano system simulator.

eMIPS is a platform developed at Microsoft Research for researching
reconfigurable computing. eMIPS allows dynamic loading and scheduling
of application-specific circuits for the purpose of accelerating
computations based on the current workload.

NetBSD eMIPS support for NetBSD 4.x was written at Microsoft Research
by Alessandro Forin and Neil Pittman. Microsoft Corporation has
donated full copyright to The NetBSD Foundation.

Platform support for eMIPS is the first part of Microsoft's
contribution. The second part includes the hardware accelerator
framework and will be proposed on tech-kern soon.
