Sock_Addr_Type has Family_Unix variant now. This variant can be created
with function Unix_Local_Addr call. And this variant is working in
GNAT.Socket routines where it is appropriate.

(SIZEOF_sockaddr_un): Idem.
* libgnat/g-socket.ads (Family_Type): New value Family_Unix
added.
(Family_Inet_4_6): New subtype only for network families.
(Sock_Addr_Type): Add Unbounded_String field for Family_Unix
variant.
(Unix_Socket_Address): Create Sock_Addr_Type from socket
pathname.
(Network_Socket_Address): Create Sock_Addr_Type from
Inet_Addr_Type and Port_Type parameters.
* libgnat/g-socket.adb: Support local unix address in socket
routines.

maximum number of characters in local socket address path.
(Sockaddr): Add variant for Family_Unix address family. Move
Sin_Port and Sin_Family to Family_Inet section. Add Sin6_Port
and Sin6_Family to Family_Inet6 section.
(Set_Address): Add out parameter Length to return valuable
Sockaddr data length.
(Get_Address): Add input parameter Length to set valuable
Sockaddr data length.
