0) Adjust BIP30 enforcement values
1) Reduce amount that peers can adjust our time to eliminate an attack vector. Thanks to
coblee for this fix.
2) Zeitgeist2 patch - thanks to Lolcust and ArtForz. This fixes an issue where a
51% attack can change difficulty at will. Go back the full period unless it's the
first retarget after genesis.
3) Avoid overflow in CalculateNextWorkRequired(). Thanks to pooler for the overflow fix.
4) Zeitgeist2 bool fshift bnNew.bits(). Thanks to romanornr for this path.
5) SegWit ContextualCheckBlockHeader adjustment and extra coverage.
6) Reject peer proto version below 70002. Thanks to wtogami for this patch.
7) Send final alert message to nodes warning about removal of the alert system. Thanks to coblee for this patch.
8) Adjust default settings for Litecoin.
9) Adjust STALE_CHECK_INTERVAL value

Use `CConnmanTest` instead of `CConnman` and add the nodes to it
so that their `fDisconnect` flag is set during disconnection.
Github-Pull: #21571
Rebased-From: 637bb6da36
This is a non-functional change that replaces the `CNode` on-stack
variables with `CNode` pointers.
The reason for this is that it would allow us to add those `CNode`s
to `CConnman::vNodes[]` which in turn would allow us to check that they
are disconnected properly - a `CNode` object must be in
`CConnman::vNodes[]` in order for its `fDisconnect` flag to be set.
If we store pointers to the on-stack variables in `CConnman` then it
would crash at the end, trying to `delete` them.

This removes the DEFINED->FAILED transition and changes the
STARTED->FAILED transition to only occur if signalling didn't pass the
threshold. This ensures that it is always possible for activation to
occur, no matter what settings are chosen, or the speed at which blocks
are found.
Github-Pull: #21377
Rebased-From: f054f6bcd2
Previously we used deployments that would timeout prior to Bitcoin's
invention, which allowed the deployment to still be activated in unit
tests. This switches those deployments to be truly never active.
Github-Pull: #21377
Rebased-From: 55ac5f568a
This generalises the ComputeBlockVersion test so that it can apply to
any activation parameters we might set, and checks all the parameters
set for each deployment on each chain, to simultaneously ensure that the
deployments we have configured work sensibly, and that the test code
does not suffer bitrot in the event that all interesting deployments
are buried.
Github-Pull: #21377
Rebased-From: 5932744450
The intent here is to allow checking ComputeBlockVersion behaviour with
each deployment, rather than only testdummy on mainnet. This commit does
the trivial refactoring component of that change.
