Drop server support for FE/BE protocol version 1.0.

Enterprise / PostgreSQL - Tom Lane [sss.pgh.pa.us] - 11 October 2016 11:19 UTC

While this isn't a lot of code, it's been essentially untestable for a very long time, because libpq doesn't support anything older than protocol 2.0, and has not since release 6.3. There's no reason to believe any other client-side code still uses that protocol, either.
