ae82896268 Consistently mark std(in|out|err) with .Dv, because that's how they 
are marked up in stdio(3), and because they are defined expressions
of type "FILE *".

cf04ed1bdf bde points out that the LIBC_MAJOR macro doesn't exist and requests 
that we not use it here.  In its place I've put a comment about the
current state of play.

c906b66373 Restore Peter's version of static __sF. There's too much pain for it 
to be static for 5.0.  I may remove this for 5.1 or 5.2.  No more
binaries or libarires will be generated with __sF starting as of
yesterday.  Originally the plan had been to eliminate this for 5.0,
but we didn't get the __std{in,out,err}p changes merged into -stable
until yesterday (rather than in September 2001 like it should have
been).  Given that didn't happen on time, we can't do the other part
of the scheme now.

# Please do not change this without talking to me first.

bd25c6f476 The field width for single-byte string conversions (%c, %s, %[) is the 
maximum number of bytes that may be stored in the array, not the maximum
number of wide characters to read. The wording of the standard unfortunately
does not make this clear.

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.

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 
assignment. This is needed on powerpc but is also more correct for the
other ports.

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.
