Instead of enabling signal handlers by default, require the user of
the library to opt-in. This is done with the call to
SCEnableDefaultSignalHandlers, which sets a flag to add the default
signal handlers.
This seems like the least invasive way to do this at this time, but it
will require some re-thinking for 9.0, especially if migrate globals
to engine instances, signal handling will need to be re-thought.
Ticket: #6814
Add library source and runmode modules. Reorganized
library example to create a worker thread and replay a pcap
file using the library mode.
No API layer is added at this stage.

Ticket: #7240
Expose LoadYamlConfig as SCLoadYamlConfig and remove it from
SuricataInit. This is required to allow the library user the ability
customize the loading of the configuration, for example doing some
programmatic configuration then loading a configuration file.
Move the contents of SuricataMain into the `main()` function found in
main.c. This forces the Suricata application to bootstrap and run
Suricata through the same interfaces as a library user might do.
Required exposing StartInternalRunMode as SCStartInternalRunmode. Its
arguable whether those "actions" belong in the library or just the
application, but I think that is separation we can look at later.
For now the lib example and Suricata's own main are the same, however
the example will probably extend more into programmatically
configuring Suricata or dynamically registering a runmode, which
doesn't really belong the main Suricata application.
Expose the functions FinalizeRunMode and ParseCommandLine to library
users, renaming with the `SC` prefix in the process.
This involves moving "application" level details from SuricataInit
into SuricataMain, as parsing command line options should be opt-in
for a library user.
Provide an example of an extremely simple application that links
against Suricata. This provides a Makefile integrated with the
Suricata build system for in-tree building, as well as an example
Makefile for building out of tree.
Currently this application just wraps SuricataMain and does nothing
else.
