Merge bitcoin/bitcoin#33819: mining: getCoinbase() returns struct instead of raw tx
48f57bb35bbdbce509b8ef195de69e2a61a2511e mining: add new getCoinbaseTx() returning a struct (Sjors Provoost)
d59b4cdb5772917ee13e48552d51662160104b62 mining: rename getCoinbaseTx() to ..RawTx() (Sjors Provoost)

Pull request description:

  The first commit renames `getCoinbaseTx()` to `getCoinbaseRawTx()` to reflect that it returns a serialised transaction. This does not impact IPC clients, because they do not use the function name.

  The second commit then introduces a replacement `getCoinbase()` that provides a struct with everything clients need to construct a coinbase. This avoids clients having to parse and manipulate our dummy transaction.

  Deprecate but don't remove `getCoinbaseRawTx()`, `getCoinbaseCommitment()` and `getWitnessCommitmentIndex()`.

  After this change we can drop these deprecated methods, which in turn would allow us to clear the dummy transaction from the `getBlock()` result. But that is left for a followup to keep this PR focussed. See https://github.com/Sjors/bitcoin/pull/106 for an approach.

  Expand the `interface_ipc.py` functional test to document its usage.

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.
