Method normalize_addr_short

  `string normalize_addr_short(string addr)`

Description

  Normalizes a formatted IPv6 address to a canonical shortest form. addr is parsed according to the hexadecimal `"x:x:x:x:x:x:x:x"` syntax or any of its shorthand varieties (see RFC 2373, section 2.2).

  The returned address is normalized as follows: The longest sequence of zeroes is shortened using `"::"`. If there are several of equal length then the leftmost is shortened. All hexadecimal letters are lower-case. There are no superfluous leading zeroes in the fields.

  Zero is returned if addr is incorrectly formatted.
