The flow allocator fa_alloc_resp would release the packet buffer (sdb)
before writing if the response was a failure. Also sets the IPCP
allocation timeout in nanoseconds as per the comment.

The state of the IPCP was set and checked in the main files, but it's
more convenient to do it in the common source.

The common enrollment code between the unicast and broadcast IPCP
included the same C source from a source file in the unicast and
broadcast directories. Now it's handled by defining COMMON_SOURCES for
the unicast and broadcast IPCP.
For now, only the enrollment component is common. Two things are
needed for the connection manager:
* Routing to be fixed to use a supporting broadcast layer. Then
management flows can be removed from the unicast IPCP (as
they are in fact data transfer flows of the broadcast layer
that supports the routing dissemination traffic).
* DHT to enroll as part of IPCP enrollment. Now it enrolls when
a data transfer flow is established to be more akin to how
Kademlia nodes join a Kademlia DHT, but this should be
revised to adhere more to O7s enrollment concepts.
After that, the connection manager code will also be completely shared
between the unicast and broadcast layer and the connmgr will also be
common code.

The code was a bit convoluted to print hashes as hex strings. Renamed
to HASH_FMT32 and HASH_VAL32 to make clear we are printing the first
32 bits only, and added options to print 64 up to 512 bits as well.
This doesn't depend on endianness anymore. Adds a small test for the
hash (printing) functions.

Compatibility with versions of CMake older than 3.5 is deprecated from
CMake 3.27 onwards, and will be removed from a future version. Calls
to cmake_minimum_required() or cmake_policy() that set the policy
version to an older value now issue a deprecation diagnostic.
Fixed by indicating a max tested value for cmake_minimum_required().

The refactors removed the need to set the hash algorithm for the
ipcpd-udp and the ipcpd-broadcast. However, the algorithm was not set
at bootstrap, so the ipcpd-udp was trying to use an SHA3-256 instead
of an MD5, causing flow allocation over the UDP to fail. The
ipcpd-broadcast used the default, so there was no problem.
Fixed by setting the correct algorithm for these ipcpds at bootstrap.

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 structure of main functions of the IPCPs was a bit strange with a
ipcp_shutdown() call that combined waiting for a terminating signal
with stopping the internal threads. This is now revised into a
symmetrical design of
ipcp_start(), which now includes the create response towards the IRMd.
ipcp_sigwait(), which waits for a shutdown signal
ipcp_stop() that then stops the internal threads.
Now the main() functions of the IPCPs will make sense without checking
what that ipcp_shutdown() functions actually does.

This fixes the RTO doubling on timeout according to Karn/Partridge.
Exponentially increasing RTO when it times out (e.g. doubling)
fixes the problem that a sudden increase in real RTT starves the sRTT
updates by never getting out of backoff as retransmitted packets can't
update RTT.
Added an parameter to make it less aggressive, default is doubling.

This adds the option to use the Round-Trip-Time (RTT) estimation
algorithm as it is implemented in the TCP implementation in Linux. It
looks like it outperforms the TCP default algorithm, so I enabled this
one by default. Also adds the option to change the RTO timeout
calculation to include more (or less) than 4 times the mdev (specified
as a power of 2. Left the default value to 2 (so, 4 mdevs), but 3 (8
mdevs) gives better results in my tests.
