Ken Steele 8f1d75039a Enforce function coding standard 
Functions should be defined as:

int foo(void)

Rather than:
int food(void) {

All functions where changed by a script to match this standard.

Ken Steele 3c6e01f653 Replace ringbuffer in Packet Pool with a stack for better cache locality 
Using a stack for free Packet storage causes recently freed Packets to be
reused quickly, while there is more likelihood of the data still being in
cache.

The new structure has a per-thread private stack for allocating Packets
which does not need any locking. Since Packets can be freed by any thread,
there is a second stack (return stack) for freeing packets by other threads.
The return stack is protected by a mutex. Packets are moved from the return
stack to the private stack when the private stack is empty.

Returning packets back to their "home" stack keeps the stacks from getting out
of balance.

The PacketPoolInit() function is now called by each thread that will be
allocating packets. Each thread allocates max_pending_packets, which is a
change from before, where that was the total number of packets across all
threads.

Victor Julien f7b1aefaf4 Bug 1107: decoders: bail out on pseudo packets 
Flow-timeout code injects pseudo packets into the decoders, leading
to various issues. For a full explanation, see:
  https://redmine.openinfosecfoundation.org/issues/1107

This patch works around the issues with a hack. It adds a check to
each of the decoder entry points to bail out as soon as a pseudo
packet from the flow timeout is encountered.

Ticket #1107.

Victor Julien 5f307acace Pass ThreadVars ptr to various thread init funcs 
To be able to register counters from AppLayerGetCtxThread, the
ThreadVars pointer needs to be available in it and thus in it's
callers:

- DecodeThreadVarsAlloc
- StreamTcpReassembleInitThreadCtx

Eric Leblond 3088b6ac34 Add invalid pkt counter.

Eric Leblond a3465fb971 Rename 'worker' running mode to 'workers' 
This patch renamed the 'worker' running mode into 'workers'. Thus,
there is only one name in Suricata for the same thing. Backward
compatibility is ensured by replacing "worker" by "workers" when
the old name is used. A warning is printed in the log when the old
name 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:

Hello Victor
This patch modifies error treatment following our discussion on IRC.
It tries to follow the error treatment guideline I've been able to
read in the different files.
I will merge this patch in the original commit if the error treatment
seems ok for you.
