ping: add stop function

Browse Source 
ping in raw mode does some set up and sets timeout, but clean
up procedure is missing. That is needed for case if PING_RESULT() macro
is used for application exit.

Also implement stop functionality when using sockets.
Running ping is stopped when calling ping_init() again.
