Comment:

 The webstats/MainTest fails.  Maybe, remove or replace by other tests (it
 seems to test log line parsing, which is done in metrics-lib now).

 Please take a look at [https://gitweb.torproject.org/user/iwakeh/metrics-
 web.git/commit/?h=task-25520 this patch].
 I tweaked the use of streams a little.  Log line counts could be bigger
 than integer: use long in java and bigint in sql.  If you think that it
 suffices to use int (and don't want to alter the db table) please
 introduce a cast to int at before writing to the db.
