582d2cd747Cover UTXO set access with lock annotations (James O'Beirne)5693530685refactor: have CCoins* data managed under CChainState (James O'Beirne)fae6ab6aedrefactor: pcoinsTip -> CChainState::CoinsTip() (James O'Beirne) Pull request description: This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11): Parent PR: #15606 Issue: #15605 Specification: https://github.com/jamesob/assumeutxo-docs/tree/2019-04-proposal/proposal --- This change encapsulates UTXO set data within CChainState instances, removing global data `pcoinsTip` and `pcoinsviewdb`. This is necessary if we want to maintain multiple chainstates with their own rendering of the UTXO set. We introduce a class CoinsViews which consolidates the construction of a CCoins* hierarchy. This commit could be broken into smaller pieces, but it would require more ephemeral diffs to, e.g., temporarily change CCoinsViewDB's constructor invocations.

src/node/
The src/node/ directory contains code that needs to access node state
(state in CChain, CBlockIndex, CCoinsView, CTxMemPool, and similar
classes).
Code in src/node/ is meant to be segregated from code in
src/wallet/ and src/qt/, to ensure wallet and GUI
code changes don't interfere with node operation, to allow wallet and GUI code
to run in separate processes, and to perhaps eventually allow wallet and GUI
code to be maintained in separate source repositories.
As a rule of thumb, code in one of the src/node/,
src/wallet/, or src/qt/ directories should avoid
calling code in the other directories directly, and only invoke it indirectly
through the more limited src/interfaces/ classes.
The src/node/ directory is a new directory introduced in
#14978 and at the moment is
sparsely populated. Eventually more substantial files like
src/validation.cpp and
src/txmempool.cpp might be moved there.
