Default gmp-5.0.2-2

Upstream patch for the following bug (until 5.0.3 is release with this fix):

There is a GMP bug in mpn/generic/dcpi1_bdiv_q.c that causes incorrect
computation with extremely low probability, for unnormalised dividends.
The bug might also result in a decrement of memory above dividends, with
some potential security impact. The bug might affect several user-level
routines, e.g., mpz_invert, but only for operands of at least 3000 bits
(for smaller operands, a simpler algorithm is used).


Testsuite fully passes.

Signoff both,
Allan

Since the test suite passes, signoff both.
