Title: Fixed crashes on ipv4 only sysem.

This is a fundamental commit. I found that after enabling ipv6 for httpd, httpd won't start on every system that is ipv4 only (failing all test cases that needs https, with or without ipv6 support). Now it checks for ipv6 support and starts itself in ipv6 mode or ipv4 mode, depending on the result.
