The Common Application Connection Establishment Protocol (CACEP) is a
RINA construct associated with the Common Distributed Application
Protocol (CDAP). We dropped CDAP as O7s sees connection establishment
as common to all applications (though it can be a nop). The wiki
already refers to this as (O7s) Connection Establishment Protocol
(CEP).
The connection manager will now timeout waiting for CEP messages to
avoid hanging forever, configurable at build time via
CONNMGR_RCV_TIMEOUT.

The connection element was not free'd on shutdown during a connect
operation.

This is a full revision of the IRMd internal implementation.
The registry is now a proper subcomponent managing its own internal
lock (a single mutex). Some tests are added for the registry and its
data structures. Some macros for tests are added in <ouroboros/test.h>.
Flow allocation is now more symmetric between the client side (alloc)
and server size (accept). Each will create a flow in pending state
(ALLOC_PENDING/ACCEPT_PENDING) that is potentially fulfilled by an
IPCP using respond_alloc and respond_accept primitives. Deallocation
is split in flow_dealloc (application side) and ipcp_flow_dealloc
(IPCP side) to get the flow in DEALLOC_PENDING and DEALLOCATED state.
Cleanup of failed flow allocation is now properly handled instead of
relying on the sanitizer thread. The new sanitizer only needs to
monitor crashed processes.
On shutdown, the IRMd will now detect hanging processes and SIGKILL
them and clean up their fuse mountpoints if needed.
A lot of other things have been cleaned up and shuffled around a bit.

This revises the logging in the IPCPs to be a more consistent and
reduce duplicate messages in nested functions.

This moves the protobuf definition in the library to a pb/
directory. Also renames the protobuf files and does a quick review of
the #define guards in the include library to specify _LIB_ for
internal/non-public library headers.

The enrollment messages now have a 64-bit ID to easier track
enrollments in the logs in larger scale tests.

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.

The ipcp configuration struct now has internal structures for the
different IPCPs and for IPCP components of the unicast IPCP.
Split the very long IPCP main loop into individual handler functions.

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.

The connection manager and enrolment components of the unicast and
broadcast IPCP have a lot in common, as conjectured in the paper. The
initial implementation of the broadcast IPCP just duplicated the
code. This moves the shared functionality to common ground.
