test: Activate all regtest softforks at height 1, unless overridden (MarcoFalke)faad1e5ffd
Introduce -testactivationheight=name@height setting (MarcoFalke)fadb2ef2fa
test: Add extra_args argument to TestChain100Setup constructor (MarcoFalke)faa46986aa
test: Remove version argument from build_next_block in p2p_segwit test (MarcoFalke)fa086ef539
test: Remove unused ~TestChain100Setup (MarcoFalke) Pull request description: All softforks that are active at the tip of mainnet, should also be active from genesis in regtest. Otherwise their rules might not be enforced in user testing, thus making their testing less useful. To still allow tests to check pre-softfork rules, a runtime argument can change the activation height. ACKs for top commit: laanwj: Code review ACKfa4db8671b
