Log message:
Don't use buildlink framework just to do a conditional dependency for a
binary tool.  We can now use the tools framework for this.  Remove the
various nroff/groff buildlink3.mk/builtin.mk files as editors/jove was
their only user in pkgsrc.

Log message:
Remove USE_BUILDLINK3 and NO_BUILDLINK; these are no longer used.

Log message:
USE_BUILDLINK3.  (Sometimes I wonder whether this should become the default,
using NO_BUILDLINK only as absolutely needed.)

Log message:
Use nroff.buildlink3.mk to get ${NROFF}.

Log message:
Add RMD160 digests in addition to the SHA1 ones.

Log message:
Update to 4.16.0.63.  Closes PR pkg/19924 by Greg A. Woods.

Changes since 4.16:
- Portability fixes.  Most important: work around a never-to-be-fixed
  bug in ncurses (the freely redistributable termcap/terminfo
  database).
- Various minor bug fixes.  Highlights:
  + use mkstemp to avoid a security loophole
  + avoid bad interaction between metakey and xterm mouse support
    in windows wider than 95 characters
  + handle symlinks better
  + obscure bug in text justification that could hang JOVE
  + misuse of stat that only misbehaved on LINUX
