This removes the _DEFAULT_SOURCE definition in the endian header as it
should not be there. This avoids double and conflicting definitions.

This replaces the time utility functions with macros. This avoids
using library functions in the tools and also slightly speeds up the
implementation.

This adds the option to wait for the directory (DHT) to enroll on
creating a new data transfer connection. This makes scripting network
bootstraps more stable. The default setting is OFF.

This makes the TTL non-optional and allows the maximum (initial) value
of the TTL to be specified at bootstrap (the default is set to
60). The fd in the DT PCI is now called EID (Endpoint ID). The names
"dif" and "ae" have been replaced by "layer" and "component"
respectively in all sources.

The DHT will now enroll or sync when a data transfer connection is
added. This avoids the need to create a temporary data transfer
connection during enrollment (and speeds it up considerably).
The notifier system was modified to take an opaque pointer to the
object that registers as a parameter.

This removes the RIB as a datastructure and CDAP as the protocol
between IPCPs. CDAP, the rib and related sources are deprecated. The
link-state protocol policy is udpated to use its own protocol based on
a simple broadcast strategy along a tree. The neighbors struct is
deprecated and moved to the library as a generic notifier component.

This will remove the dst parameter from enroll_boot, since it was only
being used in logging. It also turns some other debug logs into info
logs, and makes the component names as they are used in logs all
lowercase.

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.

This revises the build system to have configuration per system
component. System settings can now be set using cmake.
The standard compliance defines were removed from configuration header
and are set in the sources where needed. Also some small code
refactors, such as moving the data for shims out of the ipcp structure
to the respective shims were performed.

This implements a Distributed Hash Table (DHT) based on the Kademlia
protocol, with default parameters set as used in the BitTorrent
Mainline DHT. This initial implementation is almost feature complete,
except for some things to be done after a testing period: caching and
stale peer bumping, and setting the expiration timeout via the IRM
tool.

Currently CRC32, MD5, and SHA3 (224, 256, 384 and 512 bit) are supported.

All information passed over the IRMd/IPCP boundary for using IPC
services (flow allocation, registration) is now hashed. This
effectively fixes the shared namespace between DIFs and the IRMDs.
This PR also fixes some API issues (adding const identifiers),
shuffles the include headers a bit and some small bugs.

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.

Moves the definitions of paths in the RIB for the normal IPCP to a
header ribconfig.h to avoid repetition.

This increases the threadpool size for the IPCP main loop. Starvation
was happening due to a lot of back and forth interactions between the
normal IPCPd and the IRMd.

Doing a directory query before the IPCP is has bootstrapped or is
enrolled will result in an assertion failure as the directory is not
yet ready. This fixes flow allocation over the LLC shim (which
triggers a directory query from the IRMd) with a normal IPCP present.

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.

are LGPLv2.1, the rest of the code is GPLv2.

Changes a state of the IPCP to a more correct terminology.

This adds a directory to the normal IPCP that maps names on IPCP
addresses.
