- Update to release GMP 5.0.4

Browse Source 
* Thresholds in mpn_powm_sec for both fat and non-fat builds are now used
    safely, plugging a one-word buffer overrun introduced in the 5.0.3 release
    (for non-fat) and a multi-word buffer overrun that existed since 5.0 (for
    fat).  (We have not been able to provoke malign stack smashing in any of
    the ~100 configurations explored by the GMP nightly builds, but the bug
    should be assumed to be exploitable.)
  * Two bugs in multiplication code causing incorrect computation with
    extremely low probability have been fixed.
  * A bug in the test suite causing buffer overruns during "make check",
    sometimes leading to subsequent malloc crashes, has been fixed.
  * Two bugs in the gcd code have been fixed.  They could lead to incorrect
    results, but for uniformly distributed random operands, the likelihood for
    that is infinitesimally small.  (There was also a third bug, but that was
    an incorrect ASSERT, which furthermore was not enabled by default.)
  * A bug affecting 32-bit PowerPC division has been fixed.  The bug caused
    miscomputation for certain divisors in the range 2^32 ... 2^64-1 (about 1
    in 2^30 of these).
