Change the internal format of MPFR: ZERO, INF and NAN have special values of exp.

Rename MPFR_ESIZE in MPFR_LIMB_SIZE.
Rename MPFR_ABSZISE in MPFR_ALLOC_SIZE.
Rename MPFR_INIT in MPFR_TMP_INIT (INIT1 too).
"mpfr.h" includes <gmp.h> if GMP isn't detected.
Change the way of detecting stdio.h (To check).
Use mpfr namespace for new definitions in "mpfr.h".
