Correctly verify abbreviated IPv6 SANs
[ This is a backport to the 2.1 branch. ]
IPv6 SAN-verification accommodates
["zero-compression"](https://tools.ietf.org/html/rfc5952#section-2.2).
It also accommodates non-compressed addresses.
Previously the verification of IPv6 addresses would fail unless the
address syntax matched a specific format (no zero-compression, no
leading zeroes).
As an example, the IPv6 loopback address, if represented as `::1`, would
not verify. Nor would it verify if represented as
`0000:0000:0000:0000:0000:0000:0000:0001`; however, both representations
are valid, RFC-compliant representations. The library would only accept
a very specific representation (i.e. `0:0:0:0:0:0:0:1`).
This commit addresses that shortcoming, and ensures that any valid IPv6
representation will correctly verify.
