+ Remove MPFR_CLEAR_NAN and MPFR_CLEAR_INF. Only use MPFR_CLEAR_FLAGS.

  MPFR_SET_INF, MPFR_SET_ZERO and MPFR_SET_ZERO must clear the flags before setting them.
+ Add a new test in tacosh.c : check Inf / Nan flags.
+ Use MPFR_IS_SINGULAR in all the remaining files.
+ Fix the use of MPFR_CLEAR_FLAGS.
+ mpfr-impl.h auto include gmp.h, gmp-impl.h, mpfr.h and limits.h.
+ Rename _PROTO to _MPFR_PROTO, and remove _GMP_PROTO.
+ Add MPFR_INT_SIGN macro.
+ Encapsulate a few more the sign.
