Jacob Hoffman-Andrews 87644fa46b DoH: reject non-h2 early 
Previously, non-h2 connections would be accepted, and then error out
with a verbose message "http2: session_recv from ____ failed,
error: Received bad client magic byte string". Instead, we can detect
absence of h2 support at connection time and reject with a clearer
verbose message.

Vadim Fedorenko 2e6ddd6032 netevent: parse and store rcv timestamp from sock

Vadim Fedorenko 648ad4db6f Linting change. 
Remove config parser/lexer code as it's rebuilded every time but can
break adding new config options.
Also clean up the code base to avoid mixing actual code changes and lint
issues.
