I'm also seeing the -Wconstant-conversion warnings with clang-4.0.  The
warnings about strlcpy don't appear here.  That might be something
specific to the operating system.

To address the -Wconstant-conversion warnings, I suggest changing the
variables to unsigned char * as appropriate.

However, this would require a large number of changes to all call sites
of XLogRegisterData(), because they all have a cast like this:
   XLogRegisterData((char *) &xlrec, SizeOfHashMovePageContents);

Perhaps the first argument could be changed to void *.
