Merge #11178: Add iswitness parameter to decode- and fundrawtransaction RPCs

6f39ac0 Add test for decoderawtransaction bool (MeshCollider)
bbdbe80 Add iswitness parameter to decode- and fundrawtransaction RPCs (MeshCollider)

Pull request description:

  Suggested in https://github.com/bitcoin/bitcoin/pull/10481#issuecomment-325244946, this adds the option to explicitly choose whether a serialized transaction should be decoded as a witness or non-witness transaction rather than relying on the heuristic checks in #10481. The parameter defaults to relying on #10481 if not included, but it overrides that if included.
