This patch supplements each existing connection type with an new constructor that is meant to replace the original one. The new one takes a reference to the component's environment as argument and thereby does not rely on the presence of the globally accessible 'env()' interface. The original constructors are marked as deprecated. Once we have completely abolished the use of the global 'env()', we will remove them. Fixes #1960
