Convert alert Eve logging JsonBuilder. Currently
makes heavy use of JsonBuilder being able to log Jansson's json_t
which is a temporary measure until all protocols loggers can be
converted to JsonBuilder.
New functions that replace Jansson versions with JsonBuilder
variations use "Eve" instead of "JSON".
Currently the flow logger also logs app_proto information,
but not to the flow object, but instead to the root object
of the log record.
Refactor into 2 separate methods, one for the app_proto
and one for the flow, to make this more clear, as well
as make it easier to refactor for JsonBuilder as JsonBuilder
can only write to the currently open object.
This patch adds a partial flow entry in the alert event
(if applayer or flow is selected) or simply app_proto if
it is not.
app_proto is useful as filter and aggregation field. And
the partial flow entry contains more information about the
proto as well as some volumetry info.
As the logging modules are no longer threading modules, rename
them so they don't look like they are being registered as
threading modules.
Also, move the registration to the output.c which will handle
registration of the loggers.
