conntrackd: add cthelper infrastructure (+ example FTP helper)
This patch adds the user-space helper infrastructure. It also
contains the implementation of the FTP helper in user-space.
There's one example file that you can use to configure conntrackd
as user-space connection tracking helper under:
doc/helper/conntrackd.conf
