Description:
------------
Net_IPv6::checkIPv6 wrongly validates full length IPv6 IPs that have a 
leading and/or trailing colon. 

Test script:
---------------
these three examples should return false, but return true: 
var_dump(Net_IPv6::checkIPv6("1234:5678:90AB:CDEF:1234:5678:90AB:CDEF:"));
var_dump(Net_IPv6::checkIPv6(":1234:5678:90AB:CDEF:1234:5678:90AB:CDEF"));
var_dump(Net_IPv6::checkIPv6(":1234:5678:90AB:CDEF:1234:5678:90AB:CDEF:"));


Expected result:
----------------
The three examples provided aren't valid IPv6 IPs and should return
false, 
not true.
