It won't be true, though, when we start generating binary skeletons for distributions
including third-party packages like Anaconda.

Canonicalize target module paths after they were actualized using skeleton
headers, not before. Canonicalize paths to lib directories if it's possible
(i.e. they are on the local filesystem).

Otherwise, we ended up breaking previously fixed PY-31961.

We resort to comparing plain text paths only for remote interpreter's
skeletons and use VFS operations directly in other cases.

IDEA-CR-41536 makes no sense (there will be no memory saving since "implementation-class", etc already are in memory)

extract BeanExtensionPoint and InterfaceExtensionPoint to delegate creation of adapter to ExtensionPoint

Instead of using switch, simply use different classes for different implementations and overload method to provide corresponding implementation. No need to keep kind of extension point (EP), and be prepared to a new kinds of EP.

logging: report incorrect implementation of IStubFileElementType.getStubVersion to the problematic plugin (IDEA-201589)

logging: report null elements in GotoDeclarationHandler.getGotoDeclarationTargets to the problematic plugin (IDEA-201589)

Since selection also contains a target commit for scrolling, drop it when viewport changes.
