c6bd0d5621 Don't prototype _tolower() and _toupper(). They're not supposed to be
functions, and there's no implementation of them in any case.

367ed4e13d The problem is: currently our single byte ctype(3) functions are broken
for wide characters locales in the argument range >= 0x80 - they may
return false positives.

Example 1: for UTF-8 locale we currently have:
iswspace(0xA0)==1 and isspace(0xA0)==1
(because iswspace() and isspace() are the same code)
but must have
iswspace(0xA0)==1 and isspace(0xA0)==0
(because there is no such character and all others in the range
0x80..0xff for the UTF-8 locale, it keeps ASCII only in the single byte
range because our internal wchar_t representation for UTF-8 is UCS-4).

Example 2: for all wide character locales isalpha(arg) when arg > 0xFF may
return false positives (must be 0).
(because iswalpha() and isalpha() are the same code)

This change address this issue separating single byte and wide ctype
and also fix iswascii() (currently iswascii() is broken for
arguments > 0xFF).
This change is 100% binary compatible with old binaries.

16133e1530 Move some internal macros and inlines from ctype.h to a new file, _ctype.h,
which has been repo-copied from ctype.h. This will allow us to remove
namespace pollution from <wctype.h> and to make wcwidth() an inline function
without introducing more pollution.

ddc1eded85 Prefix the names of members of _RuneLocale and its sub-structures
with ``__'' to avoid polluting the namespace. This doesn't change the
documented rune interface at all, but breaks applications that accessed
_RuneLocale directly.

423eb945c0 o Fix namespace scope issues in <ctype.h> by using the relatively new
visibility primitives.
o Implement _tolower() and _toupper() POSIX.1-2001 (XSI) macros in
  <ctype.h>.
o Reduce pollution in <runetype.h> by removing typedefs and using

o Add a typedef in <rune.h> to compensate for <runetype.h> losing its

abbd890233 o Merge <machine/ansi.h> and <machine/types.h> into a new header
called <machine/_types.h>.
o <machine/ansi.h> will continue to live so it can define MD clock
  macros, which are only MD because of gratuitous differences between
  architectures.
o Change all headers to make use of this.  This mainly involves
  changing:
    #ifdef _BSD_FOO_T_
    typedef	_BSD_FOO_T_	foo_t;
    #undef _BSD_FOO_T_

509853bbfd Makes __istype() an inline (and a non inlined) function to avoid C++
compile issues.  std::isspace(' ') was expanding to std::(!!_maskrune...)
which would cause a C++ compile error.  Making __istype() an inline
causes the expansion to be std::__istype() instead, which is valid.

f506ed7467 There is a problem in that one cannot use ctype.h at the same time as parts
of the C++ stdlib.  Our ctype.h uses symbols of the form _<X> to denote the
various character classes.  Our ctype.h also extends the usual ctype.h
offering by adding the "_T" (special) class.  Problem is parts of the STL
also use the symbol "_T" as its parameterized type.  These two uses are
incompatible.

Thus change the form of the symbols used in ctype to something that fixes
the current problem and is less likely to cause conflicts in the future.

cdd84b0211 Fixed longstanding namespace convolution involving rune_t vs wchar_t.
If _ANSI_SOURCE or _POSIX_SOURCE is defined, then <ctype.h> had to
be included before <stddef.h> or <stdlib.h> to get rune_t declared.
Now rune_t is declared perfectly bogusly in all cases when <ctype.h>
is included.

This change breaks similar (but more convoluted) convolutions in the
stddef.h in gcc distributions.  Ports of gcc should avoid using the
gcc headers.

Fix numerous ANSI conformance bugs and other nits.

ctype.h:
o There were no prototypes behind the macros (conformance bug).
o isascii() didn't have enough parentheses (plain bug).
o tolower() and toupper were always static inline (conformance
  bug?  You could undef them and take their address, but this
  gave different addresses in different modules.  You couldn't
  undef them and declare them (correctly) again).  <stdio.h>'s
  treatment of putc() shows one way to handle this problem,
  but it only works because the putc() macro is allowed to
  reevaluate its args.  I used a hack controlled by
  _EXTERNALIZE_CTYPE_INLINES_ to get <ctype.h> to generate the
  code (the previous hack involving _ANSI_LIBRARY_ goes away).
  This has the advantage that the core of the functions is only
  written down once and the disadvantage that another layer of
  functions is required.  The extra layer goes away if inline
  functions are used, leaving only the problem of understanding
  why there are functions named toupper(), __toupper and
  ___toupper() as well as a macro named toupper.
o Nothing seems to define _USE_CTYPE_LIBRARY_.  Eliminate it
o Let the user set _USE_CTYPE_INLINE_ and _DONT_USE_CTYPE_INLINE_
  for full control over inlining.
o The args for the inline functions didn't have enough
  underscores (conformance bug).
o The formatting and ordering was inconsistent (style bug).
o TODO: fix conformance bugs brought by including <runetype.h>.
