feature #19568 [Debug] Better error handling (lyrixx)

This PR was merged into the 3.2-dev branch. Discussion ---------- [Debug] Better error handling | Q | A | ------------- | --- | Branch? | master | Bug fix? | no | New feature? | yes | BC breaks? | no | Deprecations? | no | Tests pass? | - | Fixed tickets | - | License | MIT | Doc PR | symfony/symfony-docs#6870 1. Send the raw exception in the log context instead of custom formatting 2. Add config option to log/throw in Symfony all PHP errors 3. Always use an exception when a PHP error occurs 4. Expand exception in the log context in the web developer toolbar 5. Use the dumper to dump log context in the web developer toolbar --- I used the following code to produce screenshots: ```php public function indexAction(Request $request) { $this->get('logger')->info('A log message with an exception', ['exception' => new \Exception('this exception will be logged')]); error_reporting(0); for ($i=0; $i < 15; $i++) { if ($i == 5) { error_reporting(E_ALL); } if ($i == 10) { error_reporting(0); } trigger_error("Trigger error avec E_USER_NOTICE", E_USER_NOTICE); } error_reporting(E_ALL); @trigger_error("trigger_error avec E_USER_DEPRECATED", E_USER_DEPRECATED); trigger_error("trigger_error avec E_USER_DEPRECATED (not silent)", E_USER_DEPRECATED); // ... ``` ![screenshot16](https://cloud.githubusercontent.com/assets/408368/17582279/2c4239b0-5fab-11e6-8428-2eaa7372cce3.png) ![screenshot17](https://cloud.githubusercontent.com/assets/408368/17582287/30cad1ea-5fab-11e6-9b0b-de0fa9f3913b.png) ![screenshot18](https://cloud.githubusercontent.com/assets/408368/17582291/348bb574-5fab-11e6-83b0-5bfaac080838.png) Commits ------- 8f24549 [Debug] Better error handling
