1. Change the prototype of mpfr_can_round to use const.

2. Change the prototype of mpfr_round_raw_2 (remove first argument since it is
   useless).
3. Change round_raw_generic to use preprocessor if rather than compiler
   to detect if flag == 1 or 0
4. mpfr_round_raw_xxx use const attribute too.
5. Remove mpfr_round_raw_3 since it is unused by MPFR.
6. Add first prototype of MPFR_FAST_COMPUTE_IF_SMALL.
