[src/urandom.c] Partly rewrote mpfr_urandom() so that the next
random state no longer depends on the current exponent range
and the rounding mode, and that the exceptions due to the
rounding of the random number are now correctly generated.
[doc/mpfr.texi] Updated the mpfr_urandom() documentation and
updated Section "API Compatibility / Changed Functions" to
mention the change in MPFR 4.0.
[NEWS] Mentioned the change for MPFR 4.0.
