Coroutines on EDT and Locks

Access is allowed with explicit read lock. Now each coroutine scheduled on EDT wrapped in implicit write intent lock (which implies read lock too). This implicit lock will be removed in future releases. Please, use explicit lock API like ReadAction.run(), WriteIntentReadAction.run(), readAction() or writeIntentReadAction() to wrap code which needs lock to access model or PSI. Please note, that read action API can re-schedule your code to background threads, if you are sure that your code need to be executed on EDT, you need to use write intent read action.
