There was an error in number validation check. If boundary value was an empty string, validation of a number always failed. This patch fixes the problem by not performing the check in these cases. https://fedorahosted.org/freeipa/ticket/3066
Added support of parsing and validation of IPv4 and IPv6 addresses. Class IP.address can also create reverse address from any valid IPv4 or IPv6 address. This functionality is needed for tickets: https://fedorahosted.org/freeipa/ticket/1466 https://fedorahosted.org/freeipa/ticket/1975
