cd20cc0632 check_icmp: add long options, add output format option 
This commit switches check_icmp from getopt to getopt_long
to provide long options too and (most importantly) homogenize
option parsing between the different plugins.

2bea8e9522 check_icmp: Remove signal handling and timeouts 
The timeout option was redundant in that the runtime
of check_icmp was always limited by the input parameters
and therefore timeout gets removed with this commit to
avoid that confusion.

The rest of the signal handlings was removed too, since
the added complexity does not provide sufficient returns.
If check_icmp gets a signal, it now dies like most other
programs instead of trying to save some things and return a
(arguably wrong) result.

0488426c7e check_icmp: keep performance data order in case of none-reachable hosts 
For responding hosts nothing changes:

    ./check_icmp -H 10.0.0.1
    OK - 10.0.0.1 rta 0.336ms lost 0%|rta=0.336ms;200.000;500.000;0; rtmax=0.471ms;;;; rtmin=0.000ms;;;; pl=0%;40;80;0;100

In case the host is down, the performance data now contain 'U' according to:
https://www.monitoring-plugins.org/doc/guidelines.html#AEN201

Old:
    ./check_icmp -H 10.0.0.99
    CRITICAL - 10.0.0.99: Host unreachable @ 10.0.1.138. rta nan, lost 100%|pl=100%;40;80;0;100

Old:
    ./check_icmp -H 10.0.0.99
    CRITICAL - 10.0.0.99: Host unreachable @ 10.0.1.138. rta nan, lost 100%|rta=U;;;; rtmax=U;;;; rtmin=U;;;; pl=100%;40;80;0;100

This confuses some performance graphing tools, ex.: pnp.
