nDPId-test: added JSON distribution + JSON parsing (Multithreaded design re-using most of nDPId/nDPIsrvd core)

* improved Makefile.old install targets
 * splitted nDPIsrvd_parse into nDPIsrvd_parse_line and nDPIsrvd_parse_all for the sake of readability
 * minor Python script improvments (check for nDPIsrvd.py on multiple locations, may be superseeded by setuptools in the future)
 * some paths needs to be absolute (chdir() during daemonize) and therefor additional checks introduced
 * test run script checks and fails if certain files are are missing (PCAP file <=> result output file)
 * removed not very useful "internal format error" JSON serialization if a BUG for same exists
 * fixed invalid l4 type statistics counters for nDPIsrvd-collectd
