perf: cgi-mode 1700% improvement (#933)
* major perf
* clean up before thread returns
* fix lint
* clean up and refactor server-context initialization
* removing the request-startup memset
I'm electing to remove the memset at startup and keeping it in shutdown. Why? Security! Keeping around the request data after a request may result in a leak of important information in a core dump or something. By setting it to zero when we shutdown the request, we can ensure no information is left laying around
