SegWit activation proposal with 2MB Hard Fork by next Block Halving on 2020

*Proposal*: Verify whether 50% Tx mined from SegWit activation block to block 630000 are SegWit Tx. If yes, increase legacy max block size to 2MB and SegWit max block size to 8MB.

*Implementation*: This proposal either needs to be implemented in next release of Bitcoin Core or require SegWit activation period restart while it is implemented & released.

*Rationale*: This proposal minimizes the chance of a chain split, while sticking to the original bitcoin scaling roadmap, i.e. https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-December/011865.html
