Damien George 2c139bbf4e py/mpz: Fix bugs with bitwise of -0 by ensuring all 0's are positive. 
This commit makes sure that the value zero is always encoded in an mpz_t as
neg=0 and len=0 (previously it was just len=0).

This invariant is needed for some of the bitwise operations that operate on
negative numbers, because they cannot handle -0.  For example
(-((1<<100)-(1<<100)))|1 was being computed as -65535, instead of 1.

Fixes issue #8042.
