bb5c24b120 validation: move g_versionbitscache into ChainstateManager (Anthony Towns)
eca22c726a test/versionbits: make versionbitscache a parameter (Anthony Towns)
d603f1d8a7 deploymentstatus: make versionbitscache a parameter (Anthony Towns)
78adef1753 refactor: use chainman instead of chainParams for DeploymentActive* (Anthony Towns)
deffe0df6c deploymentstatus: allow chainman in place of consensusParams (Anthony Towns)
eaa2e3f25c validation: move UpdateUncommittedBlockStructures and GenerateCoinbaseCommitment into ChainstateManager (Anthony Towns)
5c67e84d37 validation: replace ::Params() calls with chainstate/chainman member (Anthony Towns)
38860f93b6 validation: remove redundant CChainParams params from ChainstateManager methods (Anthony Towns)
69675ea4e7 validation: add CChainParams to ChainstateManager (Anthony Towns)

Pull request description:

  Gives `ChainstateManager` a reference to the `CChainParams` its working on, and simplifies some of the functions that would otherwise take that as a parameter. Removes the `g_versionbitscache` global by moving it into `ChainstateManager`.
