irmd: Add configuration file support

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.
