time: Remove SHA1 hashes for distfiles

Log message:
Add SHA512 digests for distfiles for time category

Problems found with mismatching existing digests for:
	distfiles/asclock-classic-1.0.tar.gz
	distfiles/asclock-gtk-2.1.10beta.tar.gz
	distfiles/asclock-xlib-2.0.11.tar.gz
	distfiles/emiclock-2.0.2.tar.gz

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Log message:
Bump PKGREVISION for libXaw API depends bump due to libXaw8 removal.

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.
