/*!
* Open the log file descriptor or a connection to the system log.
*
* This function should be called once during program initialization and
* must be called before calling FSLog() or WriteLogBuffer(). The
* fields of the given argument specify the logging destination and
* various optional features.
*
* The lopt_logLevel value specifies the initial logging level.
*
* The lopt_dest enum specifies the logging destination; either
* file based (logDest_file) or the system log (logDest_syslog).
*
* File Based Logging
* ------------------
*
* A file will be opened for log messages when the lopt_dest enum is set
* to logDest_file. The file specified by lopt_filename will be opened
* for appending log messages. A new file will be created if the log
* file does not exist.
*
* The lopt_rotateOnOpen flag specifies whether an existing log file is
* to be renamed and a new log file created during the call to OpenLog.
* The lopt_rotateOnOpen flag has no effect if the file given by
* lopt_filename is a named pipe (fifo).
*
* The lopt_rotateOnReset flag specifies whether the log file is renamed
* and then reopened when the reset signal (SIGHUP) is caught.
*
* The lopt_rotateStyle enum specifies how the new log file is renamed when
* lopt_rotateOnOpen or lopt_rotateOnReset are set. The lopt_rotateStyle
* may be the traditional Transarc style (logRotate_old) or the MR-AFS
* style (logRotate_timestamp).
*
* When lopt_rotateStyle is set to logRotate_old, the suffix ".old" is
* appended to the log file name. The existing ".old" log file is
* removed.
*
* When lopt_rotateStyle is set to logRotate_timestamp, a timestamp
* string is appended to the log file name and existing files are not
* removed.
*
* \note Messages written to stdout and stderr are redirected to the log
* file when file-based logging is in effect.
*
* System Logging
* --------------
*
* A connection to the system log (syslog) will be established for log
* messages when the lopt_dest enum is set to logDest_syslog.
*
* The lopt_facility specifies the system log facility to be used when
* writing messages to the system log.
*
* The lopt_tag string specifies the indentification string to be used
* when writing messages to the system log.
*
* \param opts logging options. A copy of the logging
* options will be made before returning to
* the caller.
*
* \returns 0 on success
