Refactor API.getSegmentsMetadata and Plugin\Segment so segments are all defined through Plugin\Segment class in dimensions & make sure AutoSuggestAPITest data providers do not use database.

This reverts commit 93f4c414.

Add tracker requests excluded due to unknown URLs to NoVisitsTest fixture so it will be tested in system tests.

Update misc/log-analytics repo for https://github.com/piwik/piwik-log-analytics/issues/67 and update expected test output.

Add integration test for ArchiveTableDao class and system test for new analyze archive table command.

Add new option for [General] process_new_segments_from option, 'segment_last_edit_time'. New option sets beginning of segments archiving from last edit time (or created time if it is found). Includes tests.
