9458b164a6 New stdarg.h and varargs.h based on arm and i386 versions. 
Use __builtin_va_* instead of hand written code in va-sh.h that uses
LHS casts.  Slightly worse code is generated by gcc 3.3.3, but LHS
casts are outlawed in gcc 3.3.6 and gcc 4.

Build-tested on hpcsh (le) and mmeye (be), run-tested on hpcsh.

d5b4b78d10 Change _BSD_VA_LIST_ from "void *" to "__builtin_va_list" for newer 
gcc versions and "char *" otherwise.  This is what most other arches
use, modulo different __GNUC_PREREQ__.

This is in preparation for replacing stdarg.h and varargs.h with
versions based on __builtin_* instead of handwritten code that gcc
3.3.6 and up refuse to compile b/c of lhs casts.

Identical binary code produced.

6d30dcee75 PR/29607: Christian Biere systrace doesn't handle interrupted syscalls properly 
Instead of jumping to the default "bad" case, jump to the error handling
switch, so that we can deal with ERESTART/EJUSTRETURN properly.

- EMODE support doesn't work fine yet.
- This code is broken for dreamcast.
  dramcast call sh4_icache_sync_all() before sh4_cache_config().

a37289db57 Make disklabel(8) and fdisk(8) into "host tools " last step: build 
and install ${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-disklabel,
${TOOLDIR}/bin/${MACHINE_GNU_PLATFORM}-fdisk by "reaching over" to
the sources in ${NETBSDSRCDIR}/sbin/{disklabel fdisk}/.

To avoid clashes with a build-host's header files, especially on
*BSD, the host-tools versions of fdisk and disklabel search for
#includes such as disklabel.h, disklabel_acorn.h, disklabel_gpt.h,
and bootinfo.h in a new #includes namespace, nbinclude/.  That is,
they #include <nbinclude/sys/disklabel.h>, <nbinclude/machine/disklabel.h>,
<nbinclude/sparc64/disklabel.h>, instead of <sys/disklabel.h> and
such.  I have also updated the system headers to #include from
nbinclude/-space when HAVE_NBTOOL_CONFIG_H is #defined.

e1245a3c46 Rework the coredump code to have no explicit knownledge of how coredump 
i/o is done.  Instead, pass an opaque cookie which is then passed to a
new routine, coredump_write, which does the actual i/o.  This allows the
method of doing i/o to change without affecting any future MD code.
Also, make netbsd32_core.c [re]use core_netbsd.c (in a similar manner that
core_elf64.c uses core_elf32.c) and eliminate that code duplication.
cpu_coredump{,32} is now called twice, first with a NULL iocookie to fill
the core structure and a second to actually write md parts of the coredump.
All i/o is nolonger random access and is suitable for shipping over a stream.

3fd1802e62 Move the MI printing of `copyright' to the MD cpu_startup() code 
where the printing of `version' is already performed.
This has the benefit of allowing the copyright to be available
via dmesg(8) on platforms which need the `msgbuf' to be setup
in cpu_startup() before printed output is remembered.

b2cb7fcd8a Push back the descriptions of NaN formats, and descriptions of the 
distinction between signalling NaNs and quiet NaNs back into the
machine-dependent headers; treat the implementation of __nanf in the
same spirit.

IEEE 754 leaves the distinction between signalling NaNs and quiet NANs
to the implementation, and unlike our headers used to suggest they're
not identical in the interpretation of the fraction's MSb; in due
course, make those of hppa, mips, sh3, and sh5 reflect reality.
