Added IBD to test plan

Rebase on non-broken D3063

Fix stupid mistake.

need to fix build

Rebase on D3063 changes.

Simplify boolean logic per Mark's suggestion.

@deadalnix I tried to address your comments by changing the test in D3063 and then rebasing this Diff on top of that one.

Fix rebase

Rebased on top of test changes.

Add test for CHECKDATASIG inclusion in standard or mandatory flags.

@deadalnix I spoke with Florian recently, and he said he will be away for the next 30 days.

Add CHECKDATASIG to standard flags, not to mandatory flags.

I realized it makes more sense to combine the code and test changes together in one Diff.

Checked on my local node, parameters look good.

I just realized this overlaps with @florian's D2506

rebase

Seems to cover everything of note.

Looks good.

Checks out against my local node.

After more investigation and discussion, I have decided to add banning exception, and re-implement the test based on the recent Schnorr and Segwit Recovery.

Work in progress
NULLDUMMY activation ported to Graviton
tests updated to work with recent refactors
To Do: check node banning behavior

Work in progress

Going to try to revive this for Nov 2019 Upgrade

I compared it against my home node, parameters check out.

Looks good to me.

Values check out against my local node on main net.

I checked the paramaters on my local node, they check out.

It looks fine to me.

Good idea to make sure the testnet block is common to regular testnet, as well as the upgrade testnet.

Good idea to add this

Hey @dagurval It seems this is now too late to include for "Great Wall" activation.

Given that you have asked around, and no-one seems to indicate usage of Bitcoin ABC on OpenBSD, I think it's fine to drop support for it.

Yeah, @dagurval you just need to rebase for the release notes, and then it should be ready to land

Looks fine to me.

Looks good to me
