Improve ssdp part

Do not compile CreateClientRequestPacketUlaGua if IPv6 is disable.
Cast DestAddr->sa_family from sa_family_t into int when calling
CreateServicePacket as this function has been set back to accept int in
a692e591defe6ed9a617b9b4a083964a01f7bbab.
Use switch instead of if with AF_INET and AF_INET6.
Add missing casts from AF_INET and AF_INET6 into sa_family_t when using
them to set sin_family and sin6_family.
Add missing explicit casts into size_t or lu when using integer
constants with strlen or unsigned long indexes.
Set SSDP_PAUSE to be unsigned as it is used with usleep.
