Merge bitcoin/bitcoin#22215: refactor: Add FoundBlock.found member 
5c5d0b6264 Add FoundBlock.found member (Russell Yanofsky)

Pull request description:

  This change lets IPC serialization code handle FoundBlock arguments more simply and efficiently. Without this change there was no way to determine from a FoundBlock object whether a block was found or not. So in order to correctly implement behavior of leaving FoundBlock output variables unmodified when a block was not found, IPC code would have to read preexisting output variable values from the local process, send them to the remote process, receive output values back from the remote process, and save them to output variables unconditionally. With FoundBlock.found method, the process is simpler. There's no need to read or send preexisting local output variable values, just to read final output values from the remote process and set them conditionally if the block was found.

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.
