+/*  Revsision 20220608
+ *  - removed obsolete socket_local4() and socket_remote4()
+ *  Revision 20210828, Erwin Hoffmann
+ *  - added socket_accept4()
+ *  Revision 20210226, Erwin Hoffmann
+ *  - removed dependency on ipv4socket (loose coupling)
+ *  - only single socket_tcp() and
+ *  - single socket_udp() function serving both IPv4 + IPv6
+ *  Revision 20181125, Erwin Hoffmann
+ *  - switched to 'uint_t.h'
+ *  - changed 'socket_tcp' --> 'socket_tcp4', 'socket_udp' --> 'socket_udp4'
+ *  - added 'socket_ip6optionskill'
+ *  - reordered and included backword compatible IPv6 calls
+ *  - commented multicast socket declarations
+ *  - enlarged usage for ipv4socket -> dual bind IPv4/IPv6
