79f7c6df9a Remove masking macros for getwc(), putwc(), putwchar() and getwchar(). 
Although there was nothing wrong with getwc() and putwc(), getwchar()
and putwchar() assumed that <stdio.h> had been included before <wchar.h>,
which is not allowed by the standard.

18a73315b6 Back out previous, free the buffer when __vfprintf() fails and don't bother

7733fef36f Back out previous and solve the problems a different way: move va_start/ 
va_end closer to the __vfprintf() call, free the buffer when __vfprintf()
fails and don't bother trying to shrink the buffer with realloc() before
returning it.

92cc4a5bcb Remove an unneeded call to _sfrefill() that was missed in the conversion 
from vfscanf() to vfwscanf(). It doesn't hurt to have it there, but it's
redundant since __fgetwc() will refill the buffer if it needs to.

530831782a Use the new va_copy macro to copy variable argument lists instead of 
assignment. This is needed on powerpc but is also more correct for the
other ports.

aef6a01e62 Optimise the common case where no special encoding is in use (LC_CTYPE is "C" 
or "POSIX", other European locales). Use __sgetc() and __sputc() where
possible to avoid a wasteful lock and unlock for each byte and to avoid
function call overhead.

9e6f796b0d 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_
    #endif
  to:
    #ifndef _FOO_T_DECLARED
    typedef	__foo_t	foo_t;
    #define	_FOO_T_DECLARED
