Norman Feske a7b3072cc2 Pass Env & as first argument to connection objects
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
