* Add license header where missing.
* Add missing `@since` (1.17 for most classes), except
ResourceLoaderLessVarFileModule since 1.32 (1bc62c548c).
* Remove duplicate file-level description for class-only files,
merge with the class description instead.
* Remove my own `@author` annotation from one file.
* Mark core's own FileModule subclasses as `@internal`, except
for the following which we support use of in extensions:
ResourceLoaderLessVarFileModule,
ResourceLoaderOOUIIconPackModule, and
ResourceLoaderWikiModule.

Either the server needs to omit these from the registry with
state=error output to the client (and server-side error logging),
or it needs to detect them, and transport them unchanged, so that
the existing client-side logic can handle it.
This patch does the latter.
Without the source code change in this patch, the added test case
fails due to "top" and "middle1" then being registered with
an empty array as dependencies.
