Low-level RPC changes

• Soft fork reporting in the getblockchaininfo return object has been updated. For full details, see the RPC help text. In summary:

  • The bip9_softforks sub-object is no longer returned
  • The softforks sub-object now returns an object keyed by soft fork name, rather than an array
  • Each softfork object in the softforks object contains a type value which is either buried (for soft fork deployments where the activation height is hard-coded into the client implementation), or bip9 (for soft fork deployments where activation is controlled by BIP 9 signaling).

• getblocktemplate no longer returns a rules array containing CSV and segwit (the BIP 9 deployments that are currently in active state).
