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.

branches: 1.30.14;
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.

more fenv

Change <machine/bus.h> to <sys/bus.h> throughout.

Split bus.h -> bus_{defs,funcs}.h.

Mark evbsh3/bus.h obsolete.

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: 1.26.12;
Sync with changes introduced by merging the newlock2 branch.

White space nits.

obsolete db_machdep.h

Add <machine/wchar_limits.h>.

/usr/include/$machine/_G_config.h is now obsolete after sh3 ports are
switched to gcc3. Fix the lists for all sh3 ports, not just hpcsh :).
Pointed out by Harold Gutch.

reformat whitespace

Significant overhaul of how the sets are used:

* Add an optional third field to the sets file which is a list of
comma separated keywords that control if the line is printed.
Currently supported keywords
kerberos4 ${MKKERBEROS4} != no
kerberos ${MKKERBEROS} != no
lint ${MKLINT} != no
obsolete ${obsolete} != 0.
In this case, non obsolete files are not printed.
(This will allow future support for builds with variables such as
MKHESIOD and MKYP set to "no".)

* Use sh(1)'s getopts where appropriate, and otherwise cleanup the
various scripts.

* Move defaults for sets.subr from sets.defaults into sets.subr.
Move replicated code for determining stuff such as shlibs type
from various scripts into sets.subr.

* Merge the obsolete.*, krb.*, krb4.* and lint.* into the appropriate
main lists with the relevant third field keyword(s).

Update for nathanw_sa merge.

Obsolete machine/conf.h

Catch up to new pmc header files.

remove trap.h

Fix up set lists for three of the four sh3 ports a bit.
XXX: Still wrong because of some missing toolchain stuff (gdb),
and crt{begin,end}S.o.
XXX: mmeye didn't build for me, will investigate

Add <machine/int_fmtio.h>.

Add <machine/int_limits.h>.

Add <machine/int_const.h>.

Add <machine/int_mwgwtypes.h>.

<ieeefp.h> must be installed in a machine-dependent fashion; it should
not exist on VAX.

sync with reality a little better.

remove evbsh3/mmeye.h. it shouldn't be necessary, or at least it has to
be renamed to something better.
XXX dreamcast/mmeye.h

RCS police

Add <machine/int_types.h>.

Add <machine/lock.h>

Add "machine_machdep.h".

Add package names. Later tonight or tomorrow AM, I will post a writeup of
this to tech-{pkg,install}. In short, the pkg names in (new) second
field will be used by the build process under basesrc/src/dist/pkg to
generate PLISTs. The package divisions here may be two finely or coarsely
grained, although I think they're a happy medium -- I will give more
detail/justification in the writeup.

Add <machine/math.h>.
