GH-1450: Improve printing/logging of large double/interval/time values

The modp_dtoa/modp_dtoa2 functions aren't capable of handling double
values larger than INT_MAX and fallback on using sprintf() in that
situation.  Previously, the format string to that sprintf() was "%e",
defaulting to a precision of 6, which is already too few digits to
represent a number known to be larger than INT_MAX.  Now, an sprintf()
is still performed for values larger than INT_MAX and still uses a
scientific notation format, but in a way that uses as many decimal
digits as needed to preserve information.
