This refactors ouroboros to use "program" instead of "application
process" and "process" instead of "application process instance" to
align with current naming in current Operating Systems courses instead
of the ISO nomenclature adopted by RINA. This change permeates through
the entire implementation. Also contains some minor other refactors.

This makes the threadpool use pthread_cancel instead of setting an
exit flag that threadpool managed threads check periodically. This
drastically reduces CPU consumption in the irmd when running a lot of
applications. It requires cancellation handlers in the ipcp and irmd
to be implemented to ensure safe cancellation during operation and
shutdown.

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.

APs and AP-Is were not removed from the registry entry for that name.

Setting the timeouts on flow_alloc and flow_accept will now work. This
makes some changes to the UNIX sockets used for management
communication between the APs, IRMd and IPCPs.

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 fixes bad timedwaits for the state of the reg_entry. Also
slightly revised timedwaits throughout the prototype.

When there is a burst of successive flow allocations for a certain
name, each such request will block a thread in the IRMD for
IRMD_REQ_ARR_TIMEOUT ms to allow the application some time to respond.
This refactors some parts of the IRMd.

The complete data model inside the IRMd has been restructured. The
bind operation was revised to allow binding of AP and AP instances and
register those names with different DIFs (see "irm bind" for details).
Server applications require to call ap_init with a server name
argument, client application that do not the be reachable over any DIF
can call ap_init(NULL). Calling ap_init for a client with a specified
name will not have adverse consequences for the application, but will
consume unnecessary resources in the IRMd.
Application servers can now be started at any point after the IRMd has
been started. Starting servers, binding AP names and registering names in
DIFs can be performed in any order that does not defy temporal logic.
Supports naming instances by their pid. In case of IPCP Instances
created with the IRM tool, the name assigned during "irm ipcp create"
can be used.
All the changes required updates in the tools.

This call will allow grouping AP instances of a certain AP together
which are configured identically. Adds the bind operation to dev and
updates the applications to make use of this call. Flow_alloc is now
only called with the pid and doesn't send the apn anymore.
