Use consistent parameter/variable name for EditorInfo

There are several places where EditorInfo is still called "attribute"
in our code base.  Let's call them "editorInfo" or something like that
for better readability.

This is just a mechanical code clean-up.  There should be no behavior
change and compability concern.
