Fix double-rounding bug in ceiling etc.

This is doable now that we have bignums.
* src/floatfns.c (integer_value): Remove; no longer used.
(rescale_for_division): New function.
(rounding_driver): Use it to divide properly (by using bignums)
even when arguments are float, fixing a double-rounding FIXME.
* src/lisp.h (LOG2_FLT_RADIX): Move here ...
* src/timefns.c (frac_to_double): ... from here.
* test/src/floatfns-tests.el (big-round):
Add a test to catch the double-rounding bug.
