Something seems to have changed in the travis infrastructure. It has
suddenly started complaining about 'test' usage in test_logfile.sh and
not printing out the test logs after the run.
Some changes to the glog_log sql table:
* Removed the 'glog_level' field since the standard one should be able to
handle everything now.
* Changed the 'file' column to 'src_file' and added a 'src_line' column.
* Added the sample glog log content to the test directory.
* log_format.cc, log_format_impls.cc, log_format.hh: Change
log_scanf to return a pointer to the character in the
time string that was not part of the time. Change the
generic log format to try and pull out the millisecond
value from the timestamp.
* test/Makefile.am: Fix some dist problems.
* test/logfile_generic.0: Test logfile for the generic log format.
