6e674f682e Add cross-references between wide character and single-byte character 
versions of printf() and scanf().

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.

516923dd04 Add implementations of wscanf() and related functions: fwscanf(), swscanf(), 
vfwscanf(), vswscanf(), vwscanf(). As the name suggests, these are wide-

456a491da7 Implement the %lc, %ls and %[ conversions, which read sequences of wide

a7450cd28a Implement the %ls and %lc conversions for printing wide character strings 
and wide characters. These were already documented in the manual page,
with an entry mentioning that they were not implemented yet. The XSI
%S and %C synoyms have not been added.

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.

5bb288ec92 Reimplement the functionality of fgetrune(), fputrune(), and fungetrune() 
here in terms of mbrtowc(), wcrtomb(), and the single-byte I/O functions.
The rune I/O functions are about to become deprecated in favour of the
ones provided by ISO C90 Amd. 1 and C99.

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

were in comments or text, not in actual code.

097dea9b47 Implement several of the c99 updates to scanf(3): 
- New length modifiers: hh, j, ll, t, z.

Still to do:
 - %C, %S, %lc, %ls (wide character support)
 - %a/%A (exact hex representation of floating-point numbers)

Removed old compatability equivalents:
 - %D for %ld, %O for %lo, %X for %lx, %E and %F for %le & %lf (these
   were buggy anyway, since they should have represented %Le & %Lf).
 - %[unknown uppercase char] for %ld, %[unknown lowercase char] for %d
