Log message:
- fine grained X11 dependencies for packages which have either USE_IMAKE
  or USE_X11BASE set, but don't include mk/x11.buildlink3.mk directly or
  via buildlink3.mks
- introduce BUILDLINK_PREFIX.libXpm as alias for BUILDLINK_PREFIX.xpm
  in the !modular case
- fix some cases where the check for libX11 couldn't work at all by using
  C++ for compilation without including the proper headers

Verified using a full X11_TYPE=xorg bulk build without additional
breakage. Discussed with salo@, wiz@ and send to packages@ for feedback.

Log message:
Update MASTER_SITES and/or HOMEPAGE, from Sergey Svishchev.

Log message:
Removed the superfluous "quotes" and 'quotes' from variables that don't
need them, for example RESTRICTED and SUBST_MESSAGE.*.

Log message:
Point MAINTAINER to pkgsrc-users@NetBSD.org in the case where no
developer is officially maintaining the package.

The rationale for changing this from "tech-pkg" to \ 
"pkgsrc-users" is
that it implies that any user can try to maintain the package (by
submitting patches to the mailing list).  Since the folks most likely
to care about the package are the folks that want to use it or are
already using it, this would leverage the energy of users who aren't
developers.

Log message:
Recursive revision bump / recommended bump for gettext ABI change.

Log message:
Remove some unnecessarily strong dependencies on perl that resulted
from including perl5/buildlink3.mk.  These packages just need the Perl
interpreter, and can just add "perl" to USE_TOOLS instead.

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

Log message:
Add RMD160 checksums.

Log message:
Convert to buildlink3.
