New Universal socket Address structure

A new socket address structure defined as part of the IPV6 socket API overcomes some of the drawbacks of existing struct SOCKADDR

Unlike struct sockaddr, the new struct sockaddr_storage is sufficient to accommodate any socket address structure supported by the system

struct sockaddr_storage{

uni8_t Ss_len;

sa_family_t sa_family;

};

The common socket address structure provided by the Sockaddr_storage type has the following 2-point difference compared to sockaddr:

1) If any socket address structure supported by the system has alignment needs, then Sockaddr_storage can meet the demanding alignment requirements

2) Sockaddr_storage is large enough to accommodate any socket address structure supported by the system
