Eric Leblond 3593cb051e decode: add PacketSetData funtion 
This patch adds a function which can be used to set the payload
of a packet when a zero copy mode is used.

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

Eric Leblond 49adc264bc Don't print message after SCMalloc failure. 
This patch generated via coccinelle is getting rid of logging
message after a SCMalloc failure. They were useless as SCMalloc
already displays a message.

Eric Leblond e802e1ed16 Modify Packet structure and prepare accessor. 
This patch modifies decode.c and decode.h to avoid the usage
by default of a bigger than 65535 bytes array in Packet structure.
The idea is that the packet are mainly under 1514 bytes size and
a bigger size must be supported but should not be the default.

If the packet length is bigger than DFLT_PACKET_SIZE then the
data are stored in a dynamically allocated part of the memory.

To ease the modification of the rest of the code, functions to
access and set the payload/length in a Packet have been introduced.

The default packet size can be set at runtime via the default-packet-size
configuration variable.
