Added class Dummy_argparse for python 2.4/2.6 compatability, Performance data updates

[georgehansper]

For python 2.4/2.6 compatability

• added the class Dummy_argparse for Python 2.4/2.6 compatibility
• check if class sys has the attribute maxsize, use constant 2^32-1 if not
• Performance data now outputs raw counters
• Performance data only put the warn/crit levels in the 1st set of values
• changed name of /var/tmp file to check_iftraffic_nrpe_stats.dat

Hello George, thank's a lot for this great pull request.
I do however have a few questions here and there.

Hi,

the performance data is indeed broken in master. Opsview generate no graphs, when the gauge value is sent as a counter.

However, this change will break the status checking, as that is made on the .value.
An alternative approach, including the status-fix from 27-no-warnings-nor-criticals

An addition to my above patch, in order to get performance counters in the desired value.

                     # convert to desired unit if asked
                     nagios_service.value = convert_bytes(nagios_service.value,

                 nagios_result.add(nagios_service)
