Rewritten the eurephia_log() to support syslog logging as well

Also simplified the initialisation of the logging module.  By calling
the eurephia_log_init(eurephiaCTX *, char *dest, int loglevel) function,
a log context will be setup inside the eurephiaCTX.

To close the log file, eurephia_log_close(eurephiaCTX *) must be called.

The destination string to eurephia_log_init() can be:

	- stdout:
	  Log everything to stdout
	- stderr:
	  Log everything to stderr
	- none:
	  Do no logging at all
	- syslog:<facility>
	  Log via syslog.  <facility> can be: user, local[0-7],
	  daemon or authpriv.
	- Filename
	  All logging goes to the given filename.  If the filename
	  string is not recognised by any of the reserved words above,
	  it will be handled as a filename.
