Merge #11389: Support having SegWit always active in regtest (sipa, ajtowns, jnewbery)

Browse Source 
d61845818 Have SegWit active by default (Pieter Wuille)
4bd89210a Unit tests for always-active versionbits. (Anthony Towns)
d07ee77ab Always-active versionbits support (Pieter Wuille)
18e071841 [consensus] Pin P2SH activation to block 173805 on mainnet (John Newbery)
526023aa7 Improve handling of BIP9Deployment limits (Anthony Towns)

Pull request description:

  Most tests shouldn't have to deal with the now-historical SegWit activation transition (and other deployments, but SegWit is certainly the hardest one to accomodate).

  This PR makes a versionbits starttime of -1 equal to "always active", and enables it by default for SegWit on regtest. Individual tests can override this by using the existing `-vbparams` option.

  A few unit tests and functional tests are adapted to indeed override vbparams, as they specifically test the transition.

  This is in preparation for wallet SegWit support, but I thought having earlier eyes on it would be useful.
