Gilles Peskine ca6e8aac58 Support negative zero as MPI test input ... The bignum module does not officially support "negative zero" (an mbedtls_mpi object with s=-1 and all limbs zero). However, we have a history of bugs where a function that should produce an official zero (with s=1), produces a negative zero in some circumstances. So it's good to check that the bignum functions are robust when passed a negative zero as input. And for that, we need a way to construct a negative zero from test case arguments. There are checks that functions don't produce negative zeros as output in the test suite. Skip those checks if there's a negative zero input: we don't want functions to _create_ negative zeros, but we don't mind if they _propagate_ negative zeros.
