BIP68 support (nSequence enforcement)
...
The latest version of the BIP doesn't use inversion, but does use
bitshifts.
It also uncovered a bug in the test scripts: the block timestamps
creep forward when we generate large numbers of blocks (UpdateTime
insists it be > GetMedianTimePast() so it's valid). We need to take
this into account when waiting for the median to move (reduced it from
60 to 30 seconds, since that adds about 14 seconds).

Alpha has segregated witnesses, so txid doesn't include the inputs.
That means we can create the first commit transaction before we sign
