Optimize logarithms using scm_i_big2dbl_2exp

* libguile/numbers.c (log_of_exact_integer_with_size): Removed.

  (log_of_exact_integer): Handle bignums too large to fit in a double
  using 'scm_i_big2dbl_2exp' instead of 'scm_integer_length' and
  'scm_ash'.

  (log_of_fraction): Use 'log_of_exact_integer' instead of
  'log_of_exact_integer_with_size'.
