Switch all users (except ia64) of custom machine/ansi.h to common_ansi.h

Deduplicate the code among ports and poll definitions of types
directly from a compiler.

This fixes miscompilation of certain programs that instruct compilers
to generate code for different types. This bug has been detected with
-fshort-wchar in EFI firmware.

Proposed and discussed on a mailing list (twice).

Itanium uses custom !ELF fallback switch, temporarily leave it as it is.

Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.

1. {wctype,wctrans,mbstate}_t: switch MD to MI like other
libc implementation (such as *BSD and glibc2).

2. don't typedef void * wc{type,trans}_t, suggested by soda@-san.
it may pass through compiler type check, it's harmful.
so i introduce dummy struct __tag_wc{type,trans}_t(iconv_t already does).

no ABI change was made.

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.

clean up some definitions around rune_t which are not needed anymore

fix gcc -Werror -Wmissing-braces problem
mbstate_t(this is opaque object)'s initializer should be ``{ 0 }'',
so changed 1st field of union from character array to integer.

merge ktrace-lwp.

For GCC3 and later, use the __builtin_va* constructs.

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22364, verified by myself.

add some ISO C 1995 I18N functions and types:
btowc, wctrans, towctrans, wcscoll, wcsxfrm, wctype_t and wctrans_t.

replace 'long long' with int64_t to compile stand alone program with
compiler other than GCC.

make mbstate_t bigger (32 -> 128 bytes).
XXX if you have libc after citrus locale import, please recompile libc,
and your applications that use mbstate_t (rather rare). really sorry
for the mess.

populate _BSD_MBSTATE_T_. add warning regarding to rune_t.

G/c _BSD_INTPTR_T_ and _BSD_UINTPTR_T_.

Following discussions with eeh and mrg, change most of these types so

Following discussions with eeh and mrg, change most of these types so
that they should make an ILP32 setup with an ILP32 compiler and an LP64
setup if run through an LP64 compiler. None of the data sizes actually
change right now, and any type errors that show up would have to be fixed
eventually anyway.
