This way my IDE (in this case PHPStorm) can actually follow these
references. Strg+click brings me straight to the function, and back.
I assume other tools, linters and such might benefit the same way.
I think this is worth having a bit more duplication.

They're a rudiment from the time when the extension had to be compatible
with both SFH_OBJECT_ARGS supporting and not versions of MediaWiki.
This is in the past, so unify them now by merging and or deleting the
old versions. The resulting functions don't end with "Obj" anymore.
One "common" function was left alone to be refactored at a later time,
however I've renamed it and made private.
