Add a real function for mpfr_sgn (not a call to mpfr_cmp_ui_2exp).

Add a test for mpfr_sgn.
Change the proto of mpfr_add1 and mpfr_sub1 by removing the last arg.
Simplify the logic of the sign in mpfr_sub1.
Tiny speed up for cmp/set/sqrt.
mpfr-impl auto include all the needed local header files (gmp, gmp-impl, mpfr).
