Call services_dhcpd_configure with the right parameter

Previously code segment for v4 would call both v4 and v6. Fixed to call v4 and v6 where appropriate.

Uniformize memory limits and remove old code (revised)

1) Allow setting a memory_limit up to 768M (Suhosin)
2) Remove old workarounds. Memory limits on config.inc will be new defaults

Ensure only one instance of services_dhcpd_configure runs concurrently

Fix diag_dns ipaddr set to use in IP WHOIS and IP Info

- Do not call resolve_host_addresses() when hostname cannot be resolved
by gethostbyname(). The old check was considering gethostbyname would
return NULL in this case but it returns a string with the hostname...

Removed unused variable $hostname

Input boxes with setPattern validation should not contain escape characters as they are already properly considered 'lists of characters' even when not escaped.

Prevent accessing undefined offset in IPv6.inc

On perfectly good IPs (eg. 1:2::3:4) this code could cause the following notice:
Notice: Undefined offset: 2 in IPv6.inc on line 560

On bad IPs like 1::2::3 it would not result in any notice.

This commit fixes the above problem, while making sure that only valid sequences pass validation.
