f583dca9ad COLO-compare: Improve tcp compare trace event readability
Because of previous patch's trace arguments over the limit
of UST backend, so I rewrite the patch.

51b9d495f2 Revert "COLO-compare: Optimize tcp compare trace event"
This reverts commit 0fc8aec7de.

In commit 2dfe5113b1 we split a trace event with a lot of arguments
in two, because the UST trace backend has a limit on the number
of arguments you can have in a single trace event. Unfortunately
we subsequently forgot about this, and in commit 0fc8aec7de
we merged the two trace events again, recreating the "UST backend
doesn't build" bug.

2dfe5113b1 net: split colo_compare_pkt_info into two trace events
It seems there is a limit to the number of arguments a UST trace event
can take and at 11 the previous trace command broke the build. Split the
trace into a src pkt and dst pkt trace to fix this.

The colo patch series added various trace events to the top
level trace-events file, despite the files using them being
in a sub-dir.

    colo-compare: add TCP, UDP, ICMP packet comparison

    We add TCP,UDP,ICMP packet comparison to replace
    IP packet comparison. This can increase the
    accuracy of the package comparison.
    Less checkpoint more efficiency.
