Currently it is an alias to the global ::mempool and should be used as follows. * Node code (validation and transaction relay) can use either ::mempool or node.mempool, whichever seems a better fit. * RPC code should use the added convenience getter EnsureMempool, which makes sure the mempool exists before use. This prepares the RPC code to a future where the mempool might be disabled at runtime or compile time. * Test code should use m_node.mempool directly, as the mempool is always initialized for tests.
