7082ce3e88scripted-diff: rename and de-globalise g_cs_orphans (Anthony Towns)733d85f79cMove all g_cs_orphans locking to txorphanage (Anthony Towns)a936f41a5dtxorphanage: make m_peer_work_set private (Anthony Towns)3614819864txorphange: move orphan workset to txorphanage (Anthony Towns)6f8e442ba6net_processing: Localise orphan_work_set handling to ProcessOrphanTx (Anthony Towns)0027174b39net_processing: move ProcessOrphanTx docs to declaration (Anthony Towns)9910ed755cnet_processing: Pass a Peer& to ProcessOrphanTx (Anthony Towns)89e2e0da0bnet_processing: move extra transactions to msgproc mutex (Anthony Towns)ff8d44d196Remove unnecessary includes of txorphange.h (Anthony Towns) Pull request description: Moves extra transactions to be under the `m_msgproc_mutex` lock rather than `g_cs_orphans` and refactors orphan handling so that the lock can be internal to the `TxOrphange` class. ACKs for top commit: dergoegge: Code review ACK7082ce3e88glozow: ACK7082ce3e88via code review and some [basic testing](https://github.com/glozow/bitcoin/blob/review-26295/src/test/orphanage_tests.cpp#L150). I think putting txorphanage in charge of handling peer work sets is the right direction.
