check_ping & check_fping replacement without requirements

[Andreas Ericsson]

Hey all.

I've rewritten check_fping completely.
Features / Improvements;
Includes the code from fping (in a modified state) instead of calling it 
and parsing the output.
Takes care of 'Unable to parse ping output' and such.
Fixes the 1 second maximum threshold value in check_fping, which was 
hardcoded in the fping source.
Removes the ridiculous appearance of precision down to a millionth of a 
millisecond (0.1000000 RTA), and instead gives proper and valuable 
output in a sensible manner.
Both check_ping and check_fping command line syntax works just fine, so 
it could be used to replace either one (-n and -p both denote number of 
packets to send).

Drawbacks;
Requires root privileges for raw sockets (if run setsuid it drops 
privileges again after obtaining the socket). This is common to all ping 
programs though.

ToDo:
Parallellize packet sending. This requires a different packet identity 
encoding algorithm, as well as some manner of delay so that hosts don't 
think they're being flooded, so I'll wait a while with this.

Please send info on any and all bugs you find to ae-n0Zl8IkGad4 at public.gmane.org
