Allow configuration parameters to be overrided usually a fully
qualified name such as:
vars.address-groups.HOME_NET: "7.1.2.0/24"
In configuration files (including "include" files). This allows the
overriding of a specific value deeply nested in the configuration
without having to redefine the complete top-layer object.
Ticket: 4783
Register a new runmode - DPDK. This enables a new flag on Suricata start
(--dpdk).
With the flag given, DPDK runmode is enabled.
Runmode loads the configuration and then initializes EAL.
If successful, it configures the physical NICs according to the configuration
file. After that, worker threads are initialized and then are in continuous
receive loop.
There are several NULL-pointer derefs in StreamTCPInitConfig. All of them happen because ConfGet returns 1 even if the value is NULL(due to misconfiguration for example).
This commit introduces a new function "ConfGetValue". It adds return values for NULL-pointer to ConfGet and could be used as a replacement for ConfGet.
Note: Simply modify ConfGet might not be a good idea, because there are some places where ConfGet should return 1 even if "value" is NULL. For example if ConfGet should get a Config-Leave in the yaml-hierarchy.

Set flags by default:
-Wmissing-prototypes

-Wstrict-prototypes
-Wwrite-strings
-Wcast-align
-Wbad-function-cast
-Wformat-security
-Wno-format-nonliteral
-Wmissing-format-attribute
-funsigned-char
Fix minor compiler warnings for these new flags on gcc and clang.
This patch introduces a new set of functions to the ConfGetChildValue
family. They permit to look under a default node if looking under
base node as failed. This will be used to access to default parameters
for a data type (for instance, first usage will be interface).
The input modules are needing a per interface configuration. This
implies some new operations to be able to parse easily te configuration.
The syntax of the configuration file is for example:
af-packet:
- interface: eth0
threads: 2
- interface: eth1
threads: 3
We need a way to express get a configuration variable for interface[eth0].
This is by using ConfNodeLookupKeyValue() to get the matching node. And
after that value can be fetch by using ConfGetChildValue*() functions.
Update Conf API to allow direct access to nodes.
A configuration node is now a tailq head and a tailq entry. This allows us to build
n-ary type trees to build something DOM like.
Properly process lists so a list of rule files (for example) can be loaded.
