Yeah, but OTOH we avoid the addition of a new file and we avoid changing some
meson and make files. Also the distinction is still clear as we are using a new
macro name. So that's fine by me.

I noticed that you removed the LWTRANCHE_ prefix in lwlocklist.h, while I agree
that's not needed, that could be misleading for people that grep for things like
"LWTRANCHE_XACT_BUFFER" for example. I don't think that's a big deal though.

Also, I think we don't need to read lwlocklist.h twice in generate-lwlocknames.pl.

PFA v4 where the only change compared to v3 is that it reads lwlocklist.h once
in generate-lwlocknames.pl.
