This enables user-written tools to instruct IPCPs to establish and
tear down connections (a.k.a. adjacencies) between its internal
components (Management and Data Transfer).
For more info, do "irm ipcp connect" or "irm ipcp disconnect" on the
command line.
This commit exposes a deletion bug in the RIB where FSO's fail to
unpack/parse. This will be fixed when the RIB is deprecated.

The graph adjacency manager has been deprecated in favor of providing
an external interface into the connectivity manager so that
adjacencies can be controlled from the command line, user scripts or
user applications.
The gam and its associated policies were removed from the normal IPCP
and the IRM configuration tools. The "/members" part of the RIB was
deprecated. Removal of the gam means that initial connectivity based
on changes in the RIB can't be provided, so some changes were
required throughout the normal IPCP.
The enrollment procedure was revised to establish its own
connectivity. First, it gets boot information from a peer by
establishing a connection to the remote enrollment component and
downloading the IPCP configuratoin. This is now done using its own
protocol buffers message in anticipation of deprecation of the RIB and
CDAP for communication within a DIF.
After the boot information is downloaded, it establishes a data
transfer flow for enrolling the directory (DHT). After the DHT has
enrolled, it signals the peer to that enrollment is done, and the data
transfer connection is torn down.
Signaling connections is done via the nbs struct, which is now passed
to the connmgr, which enables control of the connectivity graph from
external sources.

Our mailserver was migrated from intec.ugent.be to the central
ugent.be emailserver. This PR updates the header files to reflect this
change as well. Some header files were also homogenized if the
parameters within the functions were badly aligned.

This PR updates the normal IPCP to use the new RIB. The old ribmgr is
removed and replaced by a stub that needs to be implemented. All
components (dir, fmgr, frct) were adapted to the new RIB API. A lot
of functionality was moved outside of the ribmgr, such as the
addr_auth, which is now a component of the IPCP. The address is also
stored to the ipcpi struct. The irm tool has an option to set the gam
policy of the rib manager.

Reorganizes the normal IPCP a bit to make sure internal components do
not need to access the state of the IPCP. The IPCP has now a thread
calling accept and delegating it to the correct component based on the
AE name (this used to be in the fmgr).
Internal components are initialized upon enrollment or bootstrap of
the IPCP. If a step fails, the IPCP goes back to the INIT state, if
all components boot correctly, it goes to the operational state.
RIB synchronization is still done by sending a CDAP start/stop and
syncing with a ribmgr state, but needs revision later on.
