Merge the pping_kern_tc.c, pping_kern_xdp.c and pping_helpers.h into the single file pping_kern.c. Do not change any of the BPF code, except renaming the map ts_start to packet_ts. To handle both BPF programs kept in single ELF-file, change loading mechanism to extract and attach both tc and XDP programs from it. Also refactor main-method into several smaller functions to reduce its size. Finally, added the --force (-f) and --cleanup-interval (-c) options to the argument parsing, and improved the parsing of the --rate-limit (-r) option. NOTE: The verifier rejects program in it's current state as too large (over 1 million instructions). Setting the TCP_MAX_OPTIONS in pping_kern.c to 5 (or less) solves this. Unsure at the moment what causes the verifier to think the program is so large, as the code in pping_kern.c is identical to the one from the three files it was merged from.
