Currently, CCoinsStats is a struct with both in-params and out-params
where the hash_type and index_requested members are the only in-params.
This change removes CCoinsStats' hash_type in-param member and adds it
to the relevant functions instead.
[META] In subsequent commits, all of CCoinsStats' members which serve as
in-params will be moved out so as to make CCoinsStats a pure
out-param struct.
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.
