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.

"makes sense" deraadt@, ok sthen@ tb@

Wrap <ctype.h> and <wctype.h> so that calls go direct and the symbols not
in standard C are all weak.
Hide several symbols internal to the implementation

zap remaining rcsid.

Kill old files that are no longer compiled.

okay theo

ansify function definitions and zap some `register'

ok millert@

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

Use "extern __inline" instead of "static __inline" since the extern
flavor behaves more like a macro (which is what we want).

OK deraadt@ and tested on all platforms by various folks.

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

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.

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.

Less stupid check for 7-bit ascii in toupper/tolower
Remove useless check for EOF in isascii

Cast to unsigned int, not unsigned char, since what is being cast is an
int, not a char.

Make the functions (which get linked in if <ctype.h> isn't #included) behave
correctly. Also, don't let them segfault.

Fix RCS ids
Make sure everything uses {SYS,}LIBC_SCCS properly
