Move ctype.h defines to the _CTYPE_ prefix, avoids clashes with identifiers in ports

Even if those _[BCNLPSUX] defines are in the reserved namespace, some
ports make use of those identifiers and thus need pointless
headscratching and patches. Just use a longer reserved prefix.
We can't just #undef those defines as they are used in libc.

Change similar to what NetBSD did around 2010. Went through base builds
and an amd64 bulk build, the only fallout was lib(e)stdc++ base_ctype.h.
"make includes" will install the latest ctype.h and libstdc++ ctype_base.h.

Complete in the sense that all POSIX *locale(3) and *_l(3) functions

LC_CTYPE and we only support ASCII and UTF-8.

With important help from kettenis@, guenther@, and jca@.
Repeated testing in ports bulk builds by naddy@.
Additional testing by jca@, sebastia@, dcoppa@, and others.

lint is dead (long live the lint!), so stop using it as a cpp conditional
(namespace pollution!) or talking about its opinion on code.

Now that __only_inline is in <sys/cdefs.h>, replace the local versions in

When using GCC, we always want GNU inline semantics. Fixes issues with
-Wsystem-headers and -std=c99, where GCC 4.2 would warn that it couldn't
give us C99 inline semantics.

Remove an extraneous "& 0xff" (the cast to unsigned char is sufficient).

Use "extern __inline" instead of "static __inline" since the extern

Remove the advertising clause in the UCB license which Berkeley

Back out __EOF stuff and just use -1 in ctype.h. This is OK since
we don't want any user defines to change how the inlined ctype
functions behave.

Don't define EOF In ctype.h, some 3rd party code checks whether or
not EOF is defined to determine if stdio.h has been included.
Instead, use __EOF which should be OK wrt namespace safety.

Casting to unsigned int in isfoo() causes problems on alpha and
sparc64. Change cast back to unsigned char but do a bitwise AND
with 0xff to avoid any sign extension weirdness and to make it
impossible for us to overflow _C_ctype_. The bitwise AND is probably
not needed and may be removed later if this does not trigger compiler bugs.

fix typo; noticed by David Krause

Instead of doing "if (c == EOF) return 0;" use the hook ('?') operator
instead to make these one-liners. Works around a compiler bug on vax
that affects both the libc and inline versions identically.

make ctype macros on char 0x82 and such work

Well, as we are heading for a release people are encouraged to rebuild their
entire trees for testing anyway, I might as well do this intrusive touching
of include files now. Added openBSD tags.
