refs #5940 moved files into a subfolder framework, added autoloader to remove duplicated code to load autoload.php and to be able to register more autoloaders (eg for test files) on demand. This I got read of many includes that had to be updated all the time and that had to be updated all the time when moving iles

refs #5940 we might stay backwards compatible this way for 2 months. moved some tests from unit to integration and explained when a test is a unit test, an integration test or a system test.

refs #5940 put tests in correct folders, better testsuite names, some tests still fail and I cannot figure out why

  - moved all API URL generation logic & API response handling logic to separate classes
  - created ApiTestConfig class to hold API test options (and documentation for properties)
  - remove unnecessary IntegrationTestCase properties and methods (including apiNotToCall/apiToCall)
  - remove as many unnecessary API test options as possible (including abandonedCarts, hackDeleteRangeArchivesBefore)
  - rename checkRequestResponse to assertApiResponseHasNoError

Refs #5800, add namespaces to integration tests in root folder. Also add IntegrationTestCase to a namespace, re-add individual test @groups, move test groups to class level, and rename test files & class names so underscores are not used.

Piwik is a free/libre analytics platform. Refs #4455 GNU Package requirement to use free/libre instead of open source

 * updating all variables/methods containing Referers
 * RENAMING custom segments definition, and custom scheduled reports definition, so that when they load "Referers" segment/report it still works as expected
 * RENAMING old archived data so that archived blobs are called Referrers
  * Reverting part of 0deb2bbb
  * Update integration tests generating PDF+HTML with images on my dev box (GD 2.1 and PHP 5.5)

Fixes #3361, make sure row evolution works for get[Entry/Exit]PageTitles by adding correct label variation for those reports.

Fixes #3898, fix error that occurs when multi row evolution is called w/o labels for periods w/ no data.

Fixes #3897, make sure filter_limit limits the number of labels returned when no labels are specified with multi-row evolution and make sure it has no effect in all other row evolution cases.

Refs #3465, fix regression for flattener filter where queued filters were applied on the flattened datatable.

Fixes #3465, refactor row evolution code to fix bug where if no labels are specified and last period has no labels, no data is returned. Refactoring also contains optimization for case where no labels are specified.

Notes:
  * Simplified DataTableManipulator and derived classes.
  * Allow LabelFilter to use multiple labels. Can be used by specifying array for label query parameter (ie, label[]=...).
  * Removed getFilteredTableFromLabel function from datatable types and add getEmptyClone to DataTable_Array.
  * Added setIdSite to php tracker PiwikTracker.

Refs #2908, refactored tests so database setup (adding sites, tracking visits) are separated from API tests. Put setup code into fixtures and reused code as much as possible.

Implementing Site Search tracking & reporting in Piwik core!

 * New Admin UI to customize, for each site, wheter site search is enabled. Also options to set default values to use.
 * New Reports: Searches, Searches with no result, Search categories, Top Pages Following a Search
 * to track "No result keyword" users will have to tag their site with a JS call, or add a new parameter to the search result page &search_count=X (X being zero for no result searches)
 * Reports works with Row evolution, PDF/HTML reports, Piwik Mobile
 * idaction_url is now NULLable because, Site Search records a page with idaction_name == Keyword, and idaction_url == NULL. This ensures that the Site Searches don't create "Page URL Not defined" records. 
 * updates to Tracker JS API, new function trackSiteSearch, also added in PHP tracker
 * New fields in log_visit to track searches
 * new segment, "searches" which can be used to select visitors who did a search ie. searches>0 or those who searched a lot, ie searches>10
 
 TODO: 
  * commmit integration test, TESTING, DOCS, FAQ, release, and a nice Prayer to the universe and the stars, hoping that I can code a major new feature without any bug...
  * It would be awesome to have compatiblity with Transitions so we can see, for a given site search, what are the starting pages and Destination pages
  
 Thank you for your patience Timo, 
 and thank in advance everyone for your help Testing this new feature!

 * Fixing encoding bugs. We never noticed but there was a bug in the code (see change in XML files which are now correct).
 * Display Between X and Y even when values are the same (otherwise it looks like there's a bug)
 * fixing other tests
I'm SO glad we have nice tests coverage for this complicated code otherwise we would be totally screwed!

 * plot multiple metrics using $columns (renamed from $column)
 * plot row evolutions using optional $labels, will plot top 5 labels when omitted
 * imageGraphEvolutionUrl added to report metadata (only for reports without constant row count and Referers.getRefererType)
 * $showMetricTitle renamed to $showLegend

refs #3014
 * new report parameter 'Show Historical Graphs for the top 5 values'
 * better looking evolution graph on landcape pages

refs #3158
 * $label is now optional, will return top N=filter_limit row evolutions sorted with filter_sort_column when omitted
 * support for $idGoal
 * integration tests updated

constantRowsCount set on
 * Goals_getDaysToConversion
 * Goals_getVisitsUntilConversion
 * Referers_getRefererType

merges
 * r6874

IDEA
 * in Piwik UI, add a link 'display top 10 row evolutions' using API.getRowEvolution &label=false&filter_sort_column=xyz&filter_limit=10
 
TODO
 * fix scheduled report integration tests
 * review @reviews
