Summary0001500: remote_connect_back fails to connect when HTTP_X_FORWARDED_FOR contains comma-delimited ip addresses
Description

remote_connect_back fails to connect when HTTP_X_FORWARDED_FOR contains comma-delimited ip addresses. This usually happens when the application is behind multiple proxies. In my case, the application is behind an HAProxy and an NGINX.

I would expect that it would pull the first ip address out of the list, as usually this is the one that represents the client's ip address (see https://en.wikipedia.org/wiki/X-Forwarded-For#Format)

Steps To Reproduce
  1. Setup a php application with two levels of proxies, i.e. HAProxy -> NGINX -> apache php application
  2. configure xdebug for remote debugging with connect back: remote_enable=1 remote_connect_back=1
  3. visit php application with ?XDEBUG_SESSION_START=foo

see in the logs that it failed.
