Fix wrong scoping of {U,}LLONG_MAX. More cases, not just amd64.
PR 53298 from Roberto E. Vargas Caballero.

Since all our compilers support __DBL_* and __FLT_*, use them to define
{DBL,FLT}_{DIG,MIN,MAX}

add missing SSIZE_MIN

- Normalize inclusion protection (remove)
- Move CHAR_{MIN,MAX} to a common file.
- Fix broken comments

1. MB_LEN_MAX switch MD to MI.

Merge the ppcoea-renovation branch to HEAD.

This branch was a major cleanup and rototill of many of the various OEA
cpu based PPC ports that focused on sharing as much code as possible
between the various ports to eliminate near-identical copies of files in
every tree. Additionally there is a new PIC system that unifies the
interface to interrupt code for all different OEA ppc arches. The work
for this branch was done by a variety of people, too long to list here.

TODO:
bebox still needs work to complete the transition to -renovation.
ofppc still needs a bunch of work, which I will be looking at.
ev64260 still needs to be renovated
amigappc was not attempted.

NOTES:
pmppc was removed as an arch, and moved to a evbppc target.

Fix definitions of UCHAR_MAX/USHRT_MAX and related
types. C99 requires that these definitions promote to (signed/unsigned)
integer the same way as the types the definition is for. And since
unsigned char/short fit into an "int" on all our archs and thus promote
to signed int, the definitions must not be unsigned.

Add a new feature-test macro, _NETBSD_SOURCE. If this is defined

Add a new feature-test macro, _NETBSD_SOURCE. If this is defined
by the application, all NetBSD interfaces are made visible, even
if some other feature-test macro (like _POSIX_C_SOURCE) is defined.
<sys/featuretest.h> defined _NETBSD_SOURCE if none of _ANSI_SOURCE,
_POSIX_C_SOURCE and _XOPEN_SOURCE is defined, so as to preserve
existing behaviour.

This has two major advantages:
+ Programs that require non-POSIX facilities but define _POSIX_C_SOURCE
can trivially be overruled by putting -D_NETBSD_SOURCE in their CFLAGS.
+ It makes most of the #ifs simpler, in that they're all now ORs of the
various macros, rather than having checks for (!defined(_ANSI_SOURCE) ||
!defined(_POSIX_C_SOURCE) || !defined(_XOPEN_SOURCE)) all over the place.

I've tried not to change the semantics of the headers in any case where
_NETBSD_SOURCE wasn't defined, but there were some places where the
current semantics were clearly mad, and retaining them was harder than
correcting them. In particular, I've mostly normalised things so that
_ANSI_SOURCE gets you the smallest set of stuff, then _POSIX_C_SOURCE,
_XOPEN_SOURCE and _NETBSD_SOURCE in that order.

Tested by building for vax, encouraged by thorpej, and uncontested in
tech-userlevel for a week.

LP64 changes (copied from mips and changed CHAR_MIN/MAX to 0/0xffU).

Change _MACHINE_foo_H_ to _POWERPC_foo_H_

Be consistent with limit constants:
- use "U" suffix for unsigned constants
- use "L" suffix for long constants
- use "UL" suffix for unsigned long constants
- use hexadecimal instead of decimal

Be consistent with limit constants:

- use "UL" suffix for unsigned long constants
- use hexadecimal instead of decimal

Fixes build problems with vi (now that warnings/errors are enabled) on
mips, powerpc and arm platforms.

Preparation for the future introduction of multibyte locale.
- MB_LEN_MAX is increased to 32.
- To ensure binary compatibility for old executables
under multibyte locale, versioned setlocale is added.
- __mb_len_cur definision is added in setlocale.c
and enable it in stdlib.h .
It is also important for multibyte locale stuffs,
but I just forgot.
