Eric Leblond 12fd60b545 unix-socket: cleanup host table instead of destroying it 
This patch should fix the bug #637. Between pcap files, it uses a
new function HostCleanup() to clear tag and threshold on host with
an IP regputation. An other consequence of this modification is
that Host init and shutdown are now init and shutdown unconditionaly.

this is the number of packets and the number of invalid checksums.

Eric Leblond f8921d8a28 unix-socket: introduce API to add commands and tasks 
This patch transforms the unix socket into a flexible system to
add commands (triggered by user) and taks (run periodically).
It introduces two functions UnixManagerRegisterCommand and
UnixManagerRegisterBackroundTask to registed commands and tasks.

Other part of Suricata can then declare a new command via a simple
call of the function. In the case of a command the caller is
responsible of building the answer message using Jansson API. The
sending of the message is made by unix manager code.

Eric Leblond 20a8b9dbe5 unix-manager: add unix command socket and associated script 
This patch introduces a unix command socket. JSON formatted messages
can be exchanged between suricata and a program connecting to a
dedicated socket.
The protocol is the following:
 * Client connects to the socket
 * It sends a version message: { "version": "$VERSION_ID" }
 * Server answers with { "return": "OK|NOK" }
If server returns OK, the client is now allowed to send command.

The format of command is the following:
 {
   "command": "pcap-file",
   "arguments": { "filename": "smtp-clean.pcap", "output-dir": "/tmp/out" }
 }
The server will try to execute the "command" specified with the
(optional) provided "arguments".
The answer by server is the following:
 {
   "return": "OK|NOK",
   "message": JSON_OBJECT or information string
 }

A simple script is provided and is available under scripts/suricatasc. It
is not intended to be enterprise-grade tool but it is more a proof of
concept/example code.  The first command line argument of suricatasc is
used to specify the socket to connect to.

Configuration of the feature is made in the YAML under the 'unix-command'
section:
  unix-command:
    enabled: yes
    filename: custom.socket
The path specified in 'filename' is not absolute and is relative to the
state directory.

A new running mode called 'unix-socket' is also added.
When starting in this mode, only a unix socket manager
is started. When it receives a 'pcap-file' command, the manager
start a 'pcap-file' running mode which does not really leave at
the end of file but simply exit. The manager is then able to start
a new running mode with a new file.

To start this mode, Suricata must be started with the --unix-socket
 option which has an optional argument which fix the file name of the
socket. The path is not absolute and is relative to the state directory.

THe 'pcap-file' command adds a file to the list of files to treat.
For each pcap file, a pcap file running mode is started and the output
directory is changed to what specified in the command. The running
mode specified in the 'runmode' YAML setting is used to select which
running mode must be use for the pcap file treatment.

This requires modification in suricata.c file where initialisation code
is now conditional to the fact 'unix-socket' mode is not used.

Two other commands exists to get info on the remaining tasks:
 * pcap-file-number: return the number of files in the waiting queue
 * pcap-file-list: return the list of waiting files
'pcap-file-list' returns a structured object as message. The
structure is the following:
 {
  'count': 2,
  'files': ['file1.pcap', 'file2.pcap']
 }

Eric Leblond 6be63bdc4f tm-threads: add TM_ECODE_DONE state

Eric Leblond 42ace54137 list-keywords: fix when not using default install 
As we don't parse the YAML file when listing of keywords is asked,
suricata make a test on existence of the build-default directory.
So with a non standard (working) install (even a single configure
without option lead to a failure), the keyword listing fails
because the default logging directory does not exist.

Eric Leblond 19756488ab nfq: close the queue when leaving acquisition. 
This patch adds a call to close the queue when the acquisition
loop is ending. This way the incoming packets will be accepted
during all the shutdown phase (if the queue-bypass option of
NFQUEUE is used). At the same time the currently processed packets
will be dropped but the time scale are different: suricata will
drop 20 ms of packets and the shutdown can take 0.5 seconds.

Patch based on an idea of Victor Julien.
