This is a fix similar to btcsuite#1905. We'll always make a copy of the key in the local scope before passing it around elsewhere. Depending on the parity of the public key, the private key itself might need to be negated. A similar test is added here that fails without the patch to the signature.go file.

Thx for the review y'all! Added the intermediate copy just to make things a bit more explicit, I think this is g2g now. |
