Merge branch 'ripple/smart-escrow' into ripple/se/supported

Conflict resolution:

- features.macro: kept fixCleanup3_4_0 from develop and kept SmartEscrow at
  Supported::Yes, which is the only thing this branch changes.

+#       The gas limit is the maximum amount of gas that can be

+#       The bytecode size limit is the maximum size of a WASM extension in
