Victor Julien fca541f40e Add per app layer parser profiling
Per packet per app layer parser profiling. Example summary output:

Per App layer parser stats:

App Layer              IP ver   Proto   cnt        min      max          avg

Also added to the csv out.

In the csv out there is a new column "stream (no app)" that removes the
app layer parsers from the stream tracking. So raw stream engine performance
becomes visible.

Victor Julien 820b0ded82 Add per packet profiling.
Per packet profiling uses tick based accounting. It has 2 outputs, a summary
and a csv file that contains per packet stats.

Stats per packet include:
 1) total ticks spent
 2) ticks spent per individual thread module
 3) "threading overhead" which is simply calculated by subtracting (2) of (1).

A number of changes were made to integrate the new code in a clean way:
a number of generic enums are now placed in tm-threads-common.h so we can
include them from any part of the engine.

Code depends on --enable-profiling just like the rule profiling code.

New yaml parameters:

profiling:
  # packet profiling
  packets:

    # Profiling can be disabled here, but it will still have a
    # performance impact if compiled in.
    enabled: yes
    filename: packet_stats.log
    append: yes

    # per packet csv output
    csv:

      # Output can be disabled here, but it will still have a
      # performance impact if compiled in.
      enabled: no
      filename: packet_stats.csv

Example output of summary stats:

IP ver   Proto   cnt        min      max          avg

The proto 256 is a counter for handling of pseudo/tunnel packets.
