/* Attempts to canonicalize the IPv6 address of the URI.
*
* Multiple things happen during the canonicalization of an IPv6 address:
* 1) Any leading zero's in an h16 component are removed.
* Ex: [0001:0022::] -> [1:22::]
*
* 2) The longest sequence of zero h16 components are compressed
* into a "::" (elision). If there's a tie, the first is choosen.
*
* Ex: [0:0:0:0:1:6:7:8] -> [::1:6:7:8]
* [0:0:0:0:1:2::] -> [::1:2:0:0]
* [0:0:1:2:0:0:7:8] -> [::1:2:0:0:7:8]
*
* 3) If an IPv4 address is attached to the IPv6 address, it's
* also normalized.
* Ex: [::001.002.022.000] -> [::1.2.22.0]
*
* 4) If an elision is present, but, only represents 1 h16 component
* it's expanded.
*
* Ex: [1::2:3:4:5:6:7] -> [1:0:2:3:4:5:6:7]
*
* 5) If the IPv6 address contains an IPv4 address and there exists
* at least 1 non-zero h16 component the IPv4 address is converted
* into two h16 components, otherwise it's normalized and kept as is.
*
* Ex: [::192.200.003.4] -> [::192.200.3.4]
* [ffff::192.200.003.4] -> [ffff::c0c8:3041]
*
* NOTE:
* For unknown scheme types Windows simply copies the address over without any
* changes.
*
* IPv4 address can be included in an elision if all its components are 0's.
