trigger errors for deprecated methods in HttpFoundation component
Handle errors using a custom error handler

Without the custom handler, assertions after the first failure wouldn't be executed. This catches E_USER_DEPRECATED errors and passes everything else on to the phpunit error handler.

[FrameworkBundle] Added a check on file mime type for CodeHelper::fileExcerpt()

Fixed a bug on `CodeHelper::fileExcerpt()`.

I add a check on the file mime type because I use a phar of phpunit and when a exception throwed in a test, Symfony build a page with the stack trace of the exception.

The phpunit.phar path is in the stack trace and Symfony call `highlight_file()` function on this file path.
`highlight_file()` cannot parse the phar file and warnings are displayed.

This PR add a check on the file mime type.
**This PR can be applied on 2.0, 2.1 and master branches.**
