validation: remove nchaintx from assumeutxo metadata
This value is no longer used and is instead specified statically
in chainparams. This change means that previously generated
snapshots will no longer be usable.

a6694eaed8 [test] Add address relay tests involving outbound peers (Martin Zumsande)

d2dbfe6ff1 [test] Extract sending an addr message into a helper (Amiti Uttarwar)
c991943399 [test] Refactor the addr relay test to prepare for new tests (Amiti Uttarwar)

Pull request description:

  This extends the functional test `p2p_addr_relay.py`.
  It adds test coverage for address relay involving outbound peers, tests for both outgoing and incoming `GETADDR` requests and tests for `-blocksonly` mode.

  The initial refactors and some of the new tests were taken from Amiti Uttarwar's PR #21528 - they are general test improvements not directly tied to the change proposed there.

229ac1892d net: Combine two loops into one, and update comments (Hennadii Stepanov)
a3d090d110 net: Restrict period when cs_vNodes mutex is locked (Hennadii Stepanov)

Pull request description:

  This PR restricts the period when the `cs_vNodes` mutex is locked, prevents the only case when `cs_vNodes` could be locked before the `::cs_main`.

  This change makes the explicit locking of recursive mutexes in the explicit order redundant.

Pull request description:

  This PR is part of the [process separation project](https://github.com/bitcoin/bitcoin/projects/10).

  ---

  This change is move-only and can be easily reviewed with `--color-moved=dimmed_zebra`. The moves are needed to avoid duplicating common init code between different binaries (`bitcoin-node`, `bitcoin-wallet`, etc) in #10102. In #10102, each binary has it's own init file (`src/init/bitcoin-node.cpp`, `src/init/bitcoin-wallet.cpp`) so this PR moves the common code to `src/init/common.cpp`.

Pull request description:

  The functional test for [BIP65](https://github.com/bitcoin/bips/blob/master/bip-0065.mediawiki) / `OP_CHECKLOCKTIMEVERIFY` (`feature_cltv.py`) currently only tests one out of five conditions that lead to failure of the op-code -- by prepending the script `OP_1NEGATE OP_CHECKLOCKTIMEVERIFY OP_DROP` to a tx's first input's scriptSig, the case of "_the top item on the stack is less than 0_" is checked:

  f8462a6d27/test/functional/feature_cltv.py (L26-L35)

  This PR adds the other cases (5 in total) by taking an integer argument to the function `cltv_invalidate` that is called in a loop instead of only once per testing scenario. Here is the full list of failure conditions and how they are tested (note that the scriptSig should still be valid before activation of BIP65, when `OP_CLTV` is simply a no-op):
  * _the stack is empty_
  ➡️  prepending `OP_CHECKLOCKTIMEVERIFY` to scriptSig
  * _the top item on the stack is less than 0_
  ➡️  prepending `OP_1NEGATE OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
  * _the lock-time type (height vs. timestamp) of the top stack item and the nLockTime field are not the same_
  ➡️  prepending `OPNum(1000) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
  ➡️ setting tx.vin[0].nSequence=0 and tx.nCheckTimeLock=1296688602 (genesis block timestamp)
  * _the top stack item is greater than the transaction's nLockTime field_
  ➡️  prepending `OPNum(1000) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
  ➡️ setting tx.vin[0].nSequence=0 and tx.nCheckTimeLock=500
  * _the nSequence field of the txin is 0xffffffff_
  ➡️  prepending `OPNum(500) OP_CHECKLOCKTIMEVERIFY OP_DROP` to scriptSig
  ➡️ setting tx.vin[0].nSequence=0xffffffff and tx.nCheckTimeLock=500

  The first commit creates a helper function for the tx modification and also includes some tidying up like turning single-line to multi-line Python imports where necessary and cleaning up some PEP8 warnings. The second commit prepares the invalidation function `cltv_invalidate` and the third and the fourth use it and check for the expected reject reason strings ("Operation not valid with the current stack size", "Negative locktime" and "Locktime requirement not satisfied").

net: remove unnecessary check of CNode::cs_vSend
It is not possible to have a node in `CConnman::vNodesDisconnected` and
its reference count to be incremented - all `CNode::AddRef()` are done
either before the node is added to `CConnman::vNodes` or while holding
`CConnman::cs_vNodes` and the object being in `CConnman::vNodes`.

So, the object being in `CConnman::vNodesDisconnected` and its reference
count being zero means that it is not and will not start to be used by
other threads.

So, the lock of `CNode::cs_vSend` in `CConnman::DisconnectNodes()` will
always succeed and is not necessary.

Indeed all locks of `CNode::cs_vSend` are done either when the reference
count is >0 or under the protection of `CConnman::cs_vNodes` and the
node being in `CConnman::vNodes`.
