This revises the application flow allocator to use the flow_info
struct/message between the components. Revises the messaging to move
the use protocol buffers to its own source (serdes-irm).
Adds a timeout to the IRMd flow allocator to make sure flow
allocations don't hang forever (this was previously taken care of by
the sanitize thread).

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.

The information for an IPCP is now stored in an ipcp_info struct,
containing name and type. The IRM public API is not changed.

The layer_info had a member layer_name which is a bit
redundant.

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

Better to keep these separate during IRMd revision. Moves the qosspec
default out of the protobuf message parsing.

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.
