Current implementation of getModifiedPaths and getRenamedPaths for unparsed changes is not zero-cost. So it makes sense to have a fast size method to determine whether or not a commit can be shown in change browser.

[vcs-log] do not automatically show changes if one of the selected commits has more of them than the specified limit

We used to implicitly rely on PyTypingTypeProvider.getClassType() for this purpose
that, in turn, uses normal resolve machinery of a PyReference. But it (rightfully)
didn't work for references inside fragments created from text of alias RHS parts
as we prohibit resolving in them to avoid unstubbing of their containing files.

Easier to use just one key

Extract interface

Extract PR list model, make loader implement it
Rename components to panel+holder where applicable
This will simplify refresh since we won't have to update data in multiple places or call methods on UI panels

clearSubscriberCache uses O(numberOfModules) time to clear caches.
If we're creating a lot of MessageBuses (like loading of a project model) it leads to O(numberOfModules^2) operations. IDEA-CR-43553

avoid treating strange long hangups in newer JDKs in Unsafe.unpark() in FutureTask.finishCompletion() as leaking threads

1. Index compiled trait field annotations.
2. Add annotations from compiled trait field index to the compiled trait field.
3. Copy annotations from underlying field (e.g. compiled trait field) to the GrTraitField.
4. Run DelegateTransformationSupport after TraitTransformationSupport, since the latter one may (and will) add more
fields to the class.
5. Use context fields in DelegateTransformationSupport instead of code fields, since new fields with @Delegate might be
added during transformation process, e.g. by TraitTransformationSupport.

- explicitly close channel on external pipe close
- - avoid log pipe threads endlessly waiting for channel which is not live anymore
- add more LOG.debug
- - delegate to CloudAgentLogger outside of agent
- - guard calls to CloudAgentLogger since crossing agent boundaries is expensive

We should update layout after changing the "mySupportsCompression" flag,
just like we update it on "hideTabsIfNeed" settings change.

JBEditorTabs sets `mySupportsCompression` flag in constructor,
but it is used in super constructor via `createSingleRowLayout` method.
Thus, initial state of "hideTabsIfNeed" flag was ignored as "unsupported".

* Remove state from GitInteractiveRebaseEditorHandler (as its Closeable was ignored by everyone)
* Remove dangling Disposable from `GitRebaseEditorService.registerHandler`
  (fix another instance of IDEA-208453)
* Use try-with-resources to pass editor handlers to GitHandler
