I want to use the callable(i.e. inner class methods) in CallbackTransformer, but its current constructor is defined argument type hinting for \Closure so i can't.

The tests currently fail from time to time if the executing machine is under
heavy load. This leads to false negatives on Travis CI.

A side effect of the change is that the tests are much faster now.

return empty metadata collection if none do exist

The PropertyMetadataContainerInterface defines that the method
getPropertyMetadata() has to return an empty collection if no
metadata have been configured for the given property. Though, its
implementation in the ClassMetadata class didn't check for
existence of such metadata. This behavior led to unexpected PHP
notices when validating a property or a property value of a property
without any configured constraints (only affects the new 2.5 API).
Additionally, the getMemberMetadatas() didn't check for existing
array keys as well which has also been fixed.

I realized that the compiler pass only allows bundles to register folders to load entities / documents but not namespace alias to make things like `CmfRoutingBundle:Route` work. This is an attempt to provide a separate compiler pass for this. Maybe we should instead provide a new combined compiler pass and have users switch to the new pass if available.

When displaying the output of a process run, we must escape the `<` to avoid any formatting.

With the built-in server, it is not possible to use the external parameters: environment variables are only in `$_ENV`.
