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.

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

Move SqlDump fixture from Bencharmks dir to Fixtures dir, fix bug in core/Updates.php, tweak test environment setup and update UI submodule.

- Rename *_BaseFixture to Fixture.
- Move DB setup code to Fixture and reuse code in DatabaseTestCase.
- Make IntegrationTestCase::$defaultApiNotToCall an instance var.

Fixes #4614 Remove VisualPHPUnit from the codebase, since we don't use the tool anymore (everyone using PHPUnit in command line)

Refs #4200, do not generate docs for CacheFile class, document @api methods in Common, remove unused Common:: var, remove Common::substr and Common::strlen.

Notes:
  - Allow integration tests to compare processed files against expected files of other tests.
  - Allow integration tests to modify apiNotToCall.

Added namespaces to functions.php files in the five plugins that had one
Work in progress

Refs #4059 Work in progress: Conversion to use Namespaces: Period*, Metrics, Segment, SegmentExpression, PluginsManager.
Removed some deprecated code.

Converting Access & Auth to namespace

Notice that auto refactoring has created a nested namespace. Not sure this is what we want - so we might have to edit those nested namespaces afterwards (I think they don't look so good)

2 steps required:

1. Refactor > Move > \Piwik\Core\Config (uncheck "Create new File")
2. Refactor > Rename > Piwik_Config to Config

Refs #3124, add benchmark for MultiSites.getAll and benchmark fixture that adds 20,000 sites to the DB then tracks one pageview per site.

Get benchmarking system to work with new test structure and make it easier to run benchmarks through VisualPHPUnit.
