The 'check_boot_complete' function is renamed as 'parse_log_file'
and modified to make it usable by multiple test scripts. It now
accepts three parameters - log file name, search string and
timeout value.

It waits until the search string is found in the log file or the
timeout occurs. It returns '0' on success and '-1' on failure.
