Mark vtnerd 2021 Q1 Completed

This marks just part1 from my Q1 2021 as completed. Updating the others later. Sorry for the delay, I need to get these cleared out.

Part1 included analysis+patch to reduce binary size, a fix for TCP shutdown (closed after perfect-daemon refactor PR), (some of the work which rolled into p2) for cryptonote read performance, and some simple fixes + code reviews.
