OK, here's a patch that does it. I have not touched Meson yet.

I'm pretty disappointed of not being able to remove
generate-lwlocknames.pl (it now generates the .h, no longer the .c
file), but I can't find a way to do the equivalent #defines in CPP ...
it'd require invoking the C preprocessor twice. Maybe an intermediate
.h file would solve the problem, but I have no idea how would that work
with Meson. I guess I'll do it in Make and let somebody suggest a Meson
way.
