This is required to run coeffs_compute through SLURM as part of the
EAR learning process.

The P-States / Frequencies that are loaded from the policies are
validated against what the system supports.

This allows using MariaDB in its default configuration, which has a
passwordless root user that cannot login over TCP.

The existing MSR addresses are not supported on Coffee Lake,
and the ones that are supported return garbage.

This is *exactly* what stdout / stderr is there for.

This will only work if CPUs 0-n are enabled and CPUs n-2n are disabled.

The EAR daemon is supposed to parse entries like "NodeUseLog", but
without this change it will ignore any entry that doesn't begin with
"EARD" or "NodeDaemon".

Fixed errors in ear.conf templates. Fixed errors with the messaging API when using a network extension. Fixed a compilation warning when using old versions of MySQL or any MariaDB version
