Log message:
Fix indentation in buildlink3.mk files.

The actual fix as been done by "pkglint -F */*/buildlink3.mk", and was
reviewed manually.

There are some .include lines that still are indented with zero spaces
although the surrounding .if is indented. This is existing practice.

Log message:
Sort PLIST files.

Unsorted entries in PLIST files have generated a pkglint warning for at
least 12 years. Somewhat more recently, pkglint has learned to sort
PLIST files automatically. Since pkglint 5.4.23, the sorting is only
done in obvious, simple cases. These have been applied by running:

  pkglint -Cnone,PLIST -Wnone,plist-sort -r -F

Log message:
Bump PKGREVISION on packages depending on CUPS

This should be the last part of the renaming operation for print/cups to
print/cups-base.

Rationale: packages depending on CUPS but not relying on a functional
printing setup only need to depend on print/cups-base (equivalent to the
former print/cups). The new print/cups now depends on print/cups-base
and on print/cups-filters, thus directly providing a functional printing
setup. This bump reflects this change of dependency.

Log message:
Update dependencies on print/cups to print/cups-base

This is with the notable exception of meta-pkgs/desktop-gnome, which I
believe implies a fully functional cups.

This is still missing revision bumps - I'll be right there (first time I
am doing this on so many packages at a time).
