I have no objection to commiting this, too. But some fix would be
needed.

===
Generated lwlocknames.[ch] don't have header comment because
generate-lwlocknames.pl writes them into wrong place.

lmgr/Makefile looks to have some mistakes.
- lwlocknames.c is not generated from (or using) lwlocknames.c  so the entry "lwlocknames.c: lwlocknames.h" doesn't
looksto  be appropriate.
 
- maintainer-clean in lmgr/Makefile forgets to remove lwlocknames.c.

lwlock.c now includes lwlockname.c so such entry would be
needed. (But might not be needed because it is naturally
generated along with .h)

Perhaps uncommenting in pg_config_manual.h is left alone.
(This is not included in the diff below)
