Subject: [PATCH] Specify notion of required nodes: separately for tmpl
 application & for UpdatesRecorder

Too many nodes get into tmpl application process, which is unnecessary.
Many of those nodes are required actually only for correctly tracking
changes to nodes with WatchingTypecheckingStrategy.

Now implicitly required only nodes which are mentioned inside
constraint arguments. In other cases user must require them explicitly.
