Eric Leblond 45d5c3ca59 runmode: introduce configuration dereferencing. 
A devide configuration can be used by multiple threads. It is thus
necessary to wait that all threads stop using the configuration before
freeing it. This patch introduces an atomic counter and a free function
which has to be called by each thread when it will not use anymore
the structure. If the configuration is not used anymore, it is freed
by the free function.

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:

Eric Leblond fb36c0af12 pcap: do not leave if interface goes down 
This patch changes suricata behaviour to support interface like
ppp. Prior to this patch, a suricata listening to an interface
was leaving when the interface goes down. This patch modifies
the behaviour to automatically reconnect. Suricata retries to
open the interface every 0,5s until it succeeds.
