- We used to round long double arguments to double. Now we print
them properly.
- Bugs involving '%F', corner cases of '#' and 'g' format
specifiers, and the '.*' precision specifier have been
fixed.
- Added support for the "'" specifier to print thousands' grouping
characters in a locale-dependent manner.
- Implement the __vfprintf() side of hexadecimal floating point
support. All that is still needed is a routine to convert the
mantissa to hex digits one nibble at a time in the style of ultoa().

- __vfprintf()'s 'buf' has never been used for floating point, so
don't define it in terms of (incorrect) constants describing
floating point numbers. The actual size needed depends on
sizeof(uintmax_t) and locale details, so I slightly overestimated.
- We don't need a 308-character buffer to store the string "308".
With long doubles and %a we need more than three characters, though.

I believe have made all of libc .h's as consistent as possible.
