log: Add support for the systemd journal

The journal is a component of systemd, that captures Syslog messages,
Kernel log messages, initial RAM disk and early boot messages as well
as messages written to STDOUT/STDERR of all services, indexes them and
makes this available to the user.

It can be used in parallel, or in place of a traditional syslog daemon,
such as rsyslog or syslog-ng.

The journal offers a couple of improvements over traditional logging
facilities (e.g. advanced filtering capabilities).

This patch adds support for logging directly to the journal using its
native API.
