6a66acb565 Replace our ancient dtoa/strtod implementation with the gdtoa 
package, a more recent, generalized set of routines.  Among the
changes:
- Declare strtof() and strtold() in stdlib.h.
- Add glue to libc to support these routines for all kinds
  of ``long double''.
- Update printf() to reflect the fact that dtoa works slightly
  differently now.

As soon as I see that nothing has blown up, I will kill
src/lib/libc/stdlib/strtod.c.  Soon printf() will be able
to use the new routines to output long doubles without loss
of precision, but numerous bugs in the existing code must
be addressed first.

c297498757 Initial implementation of the C99 feature whereby calling freopen() with 
a NULL filename argument allows a stream's mode to be changed. At the
moment it just recycles the old file descriptor instead of storing the
filename somewhere and using that to reopen the file, as the standard
seems to require. Strictly conforming C99 applications probably can't
tell the difference but POSIX ones can.

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.

98ee763522 Respect locale while handling of \' flag. 
In original version grouping was hardcoded. It assumed that thousands
separator should be inserted to separate each 3 numbers. I.e. grouping
string "\003" was assumed for all cases. In correct case (per POSIX)
vfprintf should respect locale defined non-monetary (LC_NUMERIC
category) grouping sequence.

Also simplify thousands_sep handling.

2209d8a27c Back out national digits support, POSIX explicetely disallows it: 
The definition of character class digit requires that only ten characters
-the ones defining digits- can be specified; alternate digits (for
example, Hindi or Kanji) cannot be specified here. However, the encoding
may vary if an implementation supports more than one encoding.

The definition of character class xdigit requires that the characters
included in character class digit are included here also and allows for
different symbols for the hexadecimal digits 10 through 15.
