* ping/ping_common.h, ping/ping.c, ping/ping_address.c,
ping/ping_echo.c, ping/ping_router.c, ping/ping_timestamp.c,
ping/libping.c: Added common headers from ping related
files (ping.c, ping_address.c, ping_echo.c, ping_router.c,
ping_timestamp.c, libping.c) and ping6.c to ping/ping_common.h.
* ping/ping.h, ping/ping6.h, ping/ping_common.h (ping_data,
ping_efp): Moved ping_data, ping_efp from ping.h & ping6.h
to ping_common.h

ping_set_data): Moved _ping_setbuf and ping_set_data from libping.c
& ping6.c to ping_common.c
* ping/ping_common.h (ping_address, event, ping_data): Introduced new
unions ping_address and event in ping_common.h. Replaced ping efp
handler(ping_efp/ping_efp6) with event union and socket
address(sockaddr_in sockaddr_in6) with ping_address union.

use_ipv6 and all callers changed.

support implemented.
(ping_run): Added new variable I. Replaced `while' with `for' to
avoid decrementing PRELOAD.

`int ping_address (char *hostname)'. All callers and extern
declarations changed accordingly.
* ping/ping_echo.c (ping_echo): Likewise.
* ping/ping_router.c (ping_router): Likewise.
* ping/ping_timestamp.c (ping_timestamp): Likewise.
