rABC3491900468b7: [avalanche] Add proof-poll responses

Summary

Nodes will need to come to consensus on which proofs are currently active for any given stake, so they will need to handle Avalanche polls about Avalanche stake proofs themselves.

This change adds basic responses for proof polls.

Depends on D10686, D10904.

Test Plan

ninja all check-all

python test/functional/abc_p2p_avalanche_voting_proofs.py

This diff should have a dependency to the diff that creates getAvalancheVoteForBlock. What you need to do is to create a diff for the commit that adds the function, rebase this one on top of it in your local tree, and add a dependency in this diff summary. This can be done by editing the summary and add Depends on Dxxxx to it, where Dxxxx is the diff id of the previous commit.

src/net_processing.cpp
5208 ↗	(On Diff #31346)	You can take a look at the accessors in the peer manager (like isBoundToPeer or isOrphan) to get a more precise status.
src/net_processing.h
236 ↗	(On Diff #31346)	Use the dedicated type, i.e. BlockHash and pass it by const ref
237 ↗	(On Diff #31346)	Same with ProofId
test/functional/abc_p2p_avalanche_voting_proofs.py
39 ↗	(On Diff #31346)	is that really needed ?
51 ↗	(On Diff #31346)	Nit: you don't need that much blocks to be mined since you're only using the first one
73 ↗	(On Diff #31346)	Now I understand your comment regarding the proofid. The correct way to do it is to extract it from the proof you just built by deserializing it into an object that has the proofid as a property: proofobj = FromHex(LegacyAvalancheProof(), proof) # Now you can access the id as an int proofobj.proofid
91 ↗	(On Diff #31346)	Since you're testing answering the polls and not sending them, you don't need the whole quorum. You can also simplify a bit by using `sendavalancheproof` instead of `addavalanchenode`
98 ↗	(On Diff #31346)	The REJECTED case is missing
test/functional/test_framework/avatools.py
211 ↗	(On Diff #31346)	This change is good and can be its own diff

97 ↗	(On Diff #31458)	You can create a small helper to reduce the boilerplate. Also these proof have something special, and can benefit from better name (e.g. this one is conflicting with proof_0, can be conflicting_proof or something like that).

src/net_processing.cpp
2942 ↗	(On Diff #31821)	We probably want to reject an orphan, it's currently invalid after all
2947 ↗	(On Diff #31821)	Same here, this should be a rejecting error code
4453 ↗	(On Diff #31821)	So I didn't look at the failure detail, but you are locking cs_peermanager while holding cs_main which is very likely why the debug build is failing (out of order locking is a potential deadlock and the debug build will catch this). You need to release cs_main before locking the peer manager.
test/functional/abc_p2p_avalanche_voting_proofs.py
32 ↗	(On Diff #31821)	The second node is not used. This is the third time I give you this feedback in the same diff, please fix that.
57 ↗	(On Diff #31821)	This will be much clearer to pass the stakes to the helper. This lets you know remove some of the boilerplate and/or use meaningful names for the stakes
146 ↗	(On Diff #31821)	you can use `assert_raises_rpc_error` to check the rpc exception is what is expected
test/functional/test_framework/avatools.py
160 ↗	(On Diff #31821)	You're not returning a serialized proof id
172 ↗	(On Diff #31821)	Not bad per se, but you're not using it in this diff ?
198 ↗	(On Diff #31821)	Dito
228 ↗	(On Diff #31821)	This can be its own diff, there are more use cases for this helper

Fix latest feedback items. Fix failures due to lock checks by taking all required locks in once place.

src/net_processing.cpp
4743 ↗	(On Diff #31992)	This is increasing the scope of 3 locks instead of reducing the scope of a single one. You should rather try to reduce the scope of cs_main to what's really needed. It can even be its own diff.
