Merge bitcoin/bitcoin#31376: Miner: never create a template which exploits the timewarp bug 
733fa0b0a1 miner: never create a template which exploits the timewarp bug (Antoine Poinsot)

Pull request description:

  This check was introduced in #30681 but only enabled for testnet4. To avoid potentially creating an invalid block template if a soft fork to fix the timewarp attack were to activate in the future, we should have this check on all networks. It also seems wise for our miner to not support it whether or not a soft fork activates to fix it at the consensus level.

README.md

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.
