Change Details

The goal of this refactoring is to better encapsulate internals of the ecdsa library in a single module (in anticipation for removing that dependency later), and improve the general code quality. The `ECKey` class is renamed into `ECPrivkey` and now inherits `ECPubkey`. The code of the ECPrivkey is massaged into a better shape. The `MySigningKey` class, which is a wrapper around `ecdsa.SigningKey`, is now an implementation details of ecc.py, and is no longer used in transaction.py and unit tests. This diff is a big chunck of what remains to be split out of D16301. Depends on D16677
