It saves an insignificant amount of space (<0.1% of the size of libc on i386) and complicates vfprintf() and checkfmt(). Notes: svn path=/head/; revision=128819

This change makes most (relevant) stdio functions work again when the _extra file in FILE isn't initialised (and can't be without a libc function to do it since the __sFILEX structure is private to libc).

The digit before the hexadecimal-point is never 0 unless the number itself is 0. o Clarify that the exponent field represents a decimal exponent of 2. o Discuss the fact that multiple valid representations are possible. o Remove the entry in the BUGS section claiming that %[aA] is not implemented. - Remove the entry in the BUGS section claiming that the ' flag for printing thousands separators is unimplemented for floating-point. - Remove the entry in the BUGS section claiming that the L modifier reduces the precision to "double" before conversion.

The zeroing is fairly expensive, and it will never be necessary in these functions; when we support state-dependent encodings, we will pass in a pointer to the file's mbstate_t object, and only zero it at the time the file gets opened.
