nDPId: Reduced flow-updates for TCP flows to 1/4 of the timeout value.

 * nDPId: Fixed broken validation tests.
 * nDPId: Removed TICK_RESOLUTION, not required anymore.
 * c-collectd: Improved total layer4 payload calculation/update handling.
 * c-collectd: Updated RRD Graph script according to total layer4 payload changes.
 * py-flow-info.py: Fixed several bugs and syntax errors.
 * Python scripts: Added dirname(argv[0]) as search path for nDPIsrvd.py.
 * nDPIsrvd&nDPId-test: Fixed missing EPOLLERR check.
