Carl Dong c600ee3816 Only load BlockMan in BlockMan member functions
This commit effectively splits the "load block index itself" logic from
"derive Chainstate variables from loaded block index" logic.

This means that BlockManager::LoadBlockIndex{,DB} will only load what's
relevant to the BlockManager.

I strongly recommend reviewing with the following git-diff flags:

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.

This directory is at the moment sparsely populated. Eventually more substantial files like src/validation.cpp and src/txmempool.cpp might be moved there.
