Remove unused string support in scp_session_set_addr()

Browse Source 
Using the same argument for binary and text data is not a good idea. If
string support is ever needed, it should be a separate function.

Remove SCP_ADDRESS_TYPE_IPV4_BIN and SCP_ADDRESS_TYPE_IPV6_BIN, use
SCP_ADDRESS_TYPE_IPV4 and SCP_ADDRESS_TYPE_IPV6, which simplifies the
code.
