Refs #8311, add automated system test for the api_internal_call.php example script. Includes new proxy script that will call another script using Piwik's test environment, but w/o actually setting up the test env.

Create manipulator manually in proxy entrypoints instead of using TestingEnvironmentVariables::addHooks().

Rename Piwik_TestingEnvironment to TestingEnvironment and move the class to Piwik\Tests\Framework namespace. Remove manual require statements.

Define observer in proxy piwik.php through TestingEnvironment, instead of calling Piwik::addAction, since the latter needs the DI container (which is not setup yet).

Added environment validation system test (mostly failing) that tests Piwik's behavior when INI files are gone or corrupt from each Piwik endpoint (tracker/reporting UI/console). Hacked test code to make it possible and for some tests to pass.

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

refs #6116

Do not delete tracker cache in proxy piwik.php so devicedetector cache will remain after test tracking requests.

Exclude vendor/ from ReleaseCheckList <?php test and remove setupProfilerXHProf that are no longer necessary.

Fixes #5400, display useful error message when a database connection cannot be achieved. Deprecating Config.badConfigurationFile event.

Testing to catch exception for build: http://builds-artifacts.piwik.org/ui-tests.master/2606.1/screenshot-diffs/diffviewer.html

Maybe this fixes the Installation screenshot tests? http://builds-artifacts.piwik.org/ui-tests.master/2600.1/screenshot-diffs/diffviewer.html

refs #1915 reset viewDataTable parameters before each test run to remove previously persisted viewdatatable params from other test runs
