Sync typedefs.list with buildfarm, for real this time.

Sync typedefs.list with buildfarm, for real this time.

In commit da256a4a7, I manually added some typedef names to the
buildfarm-generated list so as not to cause any formatting regressions
compared to the prior manually-updated list.

About half of the additions were injection-point-related names.
It turns out that those were missing because none of the buildfarm
animals contributing typedef lists were building with
--enable-injection-points.  I rectified that on my animal sifaka,
and now those are in the list available from the buildfarm.

The other half were typedefs that didn't show up in the generated list
because our method for collecting that doesn't catch names that are
not used to declare any C variables or fields.  Such a typedef name
doesn't really add a lot of value, so we decided to get rid of them,
and that's now been done in commits 110eb4aef and be5942aee.  (Note:
I'm pretty sure there are some remaining cases of that, but we've
already accepted the ensuing odd formatting of the typedef declaration
itself.  The present fixes only dealt with typedefs that had been
manually added to typedefs.list during the v17 development cycle.)

Hence, we can now install a verbatim copy of the buildfarm's list
and not have it affect anything.  The only change is to add
InjectionPointCallback, which I'd omitted from da256a4a7 because
it chanced not to affect any pgindent decisions.
