net: ipv6: Add string_to_ip6 converter
This functions is used as a converter from IPv6 address string notation
to struct ip6_addr that is used everywhere in IPv6 implementation. For
example it is used to parse and convert IPv6 address from tftpboot
command. Conversion algorithm uses two passes, first to verify syntax and
locate colons and second pass to read the address. In case of valid IPv6
address it returns 0.
Examples of valid strings:
2001:db8::0:1234:1
2001:0db8:0000:0000:0000:0000:1234:0001
::1
::ffff:192.168.1.1
Examples of invalid strings
2001:db8::0::0 (:: can only appear once)
2001:db8:192.168.1.1::1 (v4 part can only appear at the end)
192.168.1.1 (we don't implicity map v4)
