dc(1): fix modulo operations with fractional inputs

Our dc(1) has never correctly calculated remainders with fractional inputs.
Both bmod and bdivmod seem to have copy/pasted code from bdiv, which results
in the remainder having the wrong output scale.

dc(1): fix input of non-decimal fractional numbers

Inputting fractional non-decimal numbers has never worked correctly in our
OpenBSD-derived dc(1). It truncates the input to a number of decimal places
equal to the number of hexadecimal (or whatever base) places given on the
input. That's unacceptable, because many numbers require more precision to
represent in base 10 than in their original bases.

Fix this bug by using as many decimal places as needed to represent the
input, up to the maximum of the global scale factor.

This has one mildly surprising side effect: the scale of a number entered in
non-decimal mode will no longer necessarily equal the number of hexadecimal
(or whatever base) places given on the input. I think that's an acceptable
behavior change, given that inputting fractional non-decimal numbers never
worked in the first place, and the man page doesn't specify whether trailing
zeros on the input should affect a number's scale.
