[Bitcoin-segwit2x] Update on 2M HF logic

Here are some minor updates on the 2M HF side of the equation.
1) It is planned to create technical specifications - BIPs - once the logic
is settled. It seems like we are pretty much there, barring any major
2) The fixed 2M flag day is being removed, leaving the logic as purely
"SegWit activation + 3 months"
The timing of a fixed September 21st flag day had been baked into code for
the case where miners rapidly activate bit 4. For this Impatient Miners
case, the HF would have been pushed back to a period longer than 3 months.
As of June 21, this is not needed and can be removed.
3) Hard block on block X
The traditional HF sequence is that the network fork occurs *on or after* the
HF rule change, when the miner creates the first block larger than 1M. It
is proposed to tighten this such that the HF block *must be* larger than 1M
on the block when the rule change occurs. This makes the event more
predictable by guaranteeing the fork occurs specifically at block X.
