Rename internal data structures so it's clear that they are the IRMd
representation of these objects for management purposes.
Split functionality for these objects off and and move them to their
own source files.
Rename internal functions of the IRMd to reflect this, with some small
refactoring.

This adds initial support for configuration files using the C99 TOML
parser (to be installed separately from https://github.com/cktan/tomlc99).
The default location for the IRMd configuration file is
/etc/ouroboros/irmd.conf. This is configurable at build time.
An example file will be installed in the configuration directory with
the name irmd.conf.example.
Config file support can be disabled using the DISABLE_CONFIGFILE build
option.
There were some refactors and changes to the configuration messages
and protobuf files. This works towards consolidation of protobuf C as
an option for more generic handling of serialization/deserialization
of various messages.

This add an ouroboros/pthread.h header that wraps the
pthread_..._unlock() functions for cleanup using
pthread_cleanup_push() as this casting is not safe (and there were
definitely bad casts in the code). The close() function is now also
wrapped for cleanup in ouroboros/sockets.h.
This allows enabling more compiler checks.

This revises the naming API to treat names (or reg_name in the source)
as first-class citizens of the architecture. This is more in line with
the way they are described in the article.
Operations have been added to create/destroy names independently of
registering. This was previously done only as part of register, and
there was no way to delete a name from the IRMd. The create call now
allows specifying a policy for load-balancing incoming flows for a
name. The default is the new round-robin load-balancer, the previous
behaviour is still available as a spillover load-balancer.
The register calls will still create a name if it doesn't exist, with
the default round-robin load-balancer.
The tools now have a "name" section, so the format is now
irm name <operation> <name> ...

The reg/unreg API is simplified to registering and unregistering a
single name with a single IPCP. The functionality associated with
registering names was moved from the IRMd to the irm tool. The
function to list IPCPs was simplified to return all IPCPs in the
system with their basic properties needed for management.
The above changes led to some needed changes in the irm tool and the
management functions that were depending on the previous behaviour of
list_ipcps.
Command line functionality to list IPCPs in the system is also added
to the irm tool.
Some older code was refactored.

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.

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.

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.

When there is a burst of successive flow allocations for a certain

This removes the logfile and outputs log messages to the logging
system. The creation of the logfiles (as well as the ap_init() call)

If an IPCP SEGVs abruptly, the sanitizer in the IRMd would also cause
a SEGV because of looping over a registry linked list inside another
safe loop over the same list. A function is added to the registry to
avoid this.

This adds the ability to query IPCPs if a name can be reached through
them, e.g. if a name is available in a DIF. This means that in the
shim-udp a DNS query is performed, in the shim-eth-llc an ARP-like
query has been added, in the local a check is done to see if the name
is registered, and in the normal currently no application is reachable
through it.

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.

Threads from the threadpool will now check the state of the IRMd and

When a pending accept is shutdown on irmd exit, there are no more
threads running, but it should also change the state to NULL. This is

Flow allocation requests and registered api states revised so all
states are tracked with a condition variable. This is a more reliable
approach and improves stability of flow allocation.
Some other refactoring was also done, such as renaming port_map_entry
to irm_flow and hiding some internal structures of the registry.
