http_proxy: report failed http code

Browse source 
Improve how we report what happened with http_proxy... if
we can't recognize the response as http/1.0 or http/1.1
do a CCE with "http_proxy fail", or if we did get valid h1
response but no 200 response code, do a CCE with
"http_proxy -> xxx" where xxx is the decimal representation
of the response code, eg, "http_proxy -> 407"
