Rewrite sctp_create_new_listener() to handle DNS, IPv6

Browse Source 
Rewrite sctp_create_new_listener() to use getaddrinfo() to look up
IPv4/IPv6 addresses via a common interface. This allows to use e.g. DNS,
and enables the SCTP library to listen on IPv6 ports.

To support the above, the corresponding message is changed to not take
an IPv4 address on 4 bytes (and separate IPv6), but a single name that
will be resolved via getaddrinfo()

The previous init message used to allow multiple IPv4/IPv6 addresses;
since this is not used anywhere, remove the corresponding functionality.

Modify all uses of this ITTI message to copy te SCTP init bind addr into
ITTI message.
