mod_http: Fix IP address normalization (Thanks Boris) This fixes the problem that an un-bracketed IPv6 address will not match the first pattern (since it matches brackets) and instead the first decimal digits will match the pattern meant to strip port numbers from IPv4 addresses, e.g. 2001:db8::1 --> 2000 This pattern instead matches enough of a regular IPv4 address to make an IPv6 address fall back to the last case.
