Some libx52 APIs, notably the clock related ones, can return
LIBX52_ERROR_TRY_AGAIN. This is not a real error, but it is useful
information. It indicates to the application that there is no change
applied to the internal state, and that it should wait until trying
again.
Given that the clock thread calls the libx52_set_clock method every
second, treating the TRY_AGAIN state as a failure and logging it causes
a lot of spurious noise in the logs. This change ensures that the API
returns a real error before logging it.
Having the trace log in there adds unnecessary logging for no real
reason. It is better to disable the log here to help trace other
portions of the daemon.
This change adds the daemon configuration parser and command line
argument parser. This also adds the associated strings to the
translation files, and integrates the daemon into the existing autotools
build framework.
