This modifies the majority of the tests that make use of chain parameters and the RPC tests to use the resurrected regression test network. It also bumps the affected module versions as follows: - github.com/decred/dcrd/txscript@v1.0.2 - github.com/decred/dcrd/blockchain/stake@v1.0.3 - github.com/decred/dcrd/mempool@v1.0.2 The blockchain and dcrutil modules are also affected, but since their version has already been bumped since their last release tags, they are not bumped again.
