Just in case for irrational or recurring results, the precision of the
quotient is set to at least more than 2*Float::DIG plus alpha.

Introduced in https://github.com/ruby/bigdecimal/commit/4792a917d806
`rb_absint_size` return the number of bytes needed to fit
the absolute integer, but negative integers need the sign, so one more
bit, and potentially one more byte.

Stop using logarithm to compute the number of components.
Instead, use the theoretical maximum number of components for buffer,
and count up the actual number of components during conversion.

Using dtoa of mode=0, we can determine the number of digits in decimal that is
necessary to represent the given Float number without errors.
This change permits digits=0 in BigDecimal(flt) and Float#to_d, and these
methods use dtoa of mode=0 when the given digits is 0.
Internal implicit conversion from Float also uses digits=0.

This improve the conversion speed several times faster than before.
