Merge #15948: refactor: rename chainActive
486c1eea86 refactoring: remove unused chainActive (James O'Beirne)
631940aab2 scripted-diff: replace chainActive -> ::ChainActive() (James O'Beirne)
a3a609079c refactoring: introduce unused ChainActive() (James O'Beirne)
1b6e6fcfd2 rename: CChainState.chainActive -> m_chain (James O'Beirne)
Pull request description:
This is part of the assumeutxo project:
Parent PR: #15606
Issue: #15605
Specification: https://github.com/jamesob/assumeutxo-docs/tree/2019-04-proposal/proposal
---
This change refactors the `chainActive` reference into a `::ChainActive()` call. It also distinguishes `CChainState`'s `CChain` data member as `m_chain` instead of the current `chainActive`, which makes it easily confused with the global data.
The active chain must be obtained via function because its reference will be swapped at some point during runtime after loading a UTXO snapshot.
This change, though lengthy, should be pretty easy to review since most of it is contained within a scripted-diff. Once merged, the parent PR should be easier to review.
