   This is re-base and refactoring of #589 on top of current master with the released Schnorr signature implementation.

   Still a WIP. Opening PR to make sure I am on the right path.

2. Add ec_commitments which are essentially the pay-to-contract-style tweaks of public keys.

   The functionality is not exposed.
