419c442678 Describe the restrictions on seeking on wide character streams, and also
point out that fseek() clears the ungetwc() buffer.

74a4ba21f7 Zap the early-adopter transition aid before we get into serious
5.0-R territory, as threatened.  This only affects antique 5.0
systems that have not had a 'make world' done for well over a year.

ce04c11001 Cross-reference between byte and wide-character stdio functions. Remove
references to fputwc() and fgetwc() being macros while I'm at it.

3619568a64 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.

27a29543f3 Back out previous, free the buffer when __vfprintf() fails and don't bother
trying to shrink the buffer with realloc() before returning it.

344141d1fd 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.

89265cb899 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.

d07090a880 Use the new va_copy macro to copy variable argument lists instead of

other ports.

b9aac30810 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

0b7bc80226 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.

here in terms of mbrtowc(), wcrtomb(), and the single-byte I/O functions.

ones provided by ISO C90 Amd. 1 and C99.

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