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>.

09b133a008 Remove EOF handling after Bruce explanation. This step returns
to 4.4 way to not allow EOF in ctype and now all signed chars
(including '\377' which becomes EOF) converted to (unsigned char) properly.

262fb20771 Handle EOF case in all macros by ANSI standard.
Cast all ints < 0 to (unsigned char) to fix common problem
with sign extention on signed char.
