To be honest I don't get why this lazy registration was done in the
first place. None of the 4 other hooks should ever be called before
the ParserFirstCallInit hook got called.
Also, under which circumstances can the ParserFirstCallInit hook be
called more than once?
Both scenarios would be wrong, as far as I'm concerned. Either I'm
missing something, or this code can indeed be simplified. Maybe it was
something to make it more compatible with older MediaWiki versions?
The only reason I can think of is: in all situations that do not
involve a parser, having the 4 extra hooks registered is pointless.
Does this waste space and/or runtime in the $wgHooks registry?

I was particularly suprised by the conditions that checked if
`$parser->extCite !== $this`. This can never happen. Maybe it was
possible in a very old version of this code, but it is not any more.

As of now, this patch does not touch the existing code. However, the
goal is to remove a lot of the related code from the Cite class. This
will be done in later patches. This here is a separate patch to make
reviewing the later patches much easier.
The existing parser tests should be proof enough this chain of patches
is not changing any behavior.
