OSVERSION_SPECIFIC dummy package

[Steven Drake <sbd%NetBSD.org@localhost>]

The back story to this is PR pkg/41087 "(OS_VERSION should be removed from 
PKGPATH)"

The complaint is that OS_VERSION is appended to lsof's PKGNAME, an 
alternative suggestion from David Holland is to have a dummy dependence
package that's version is OS_VERSION and I suggested making it a dependence
for all packages that set OSVERSION_SPECIFIC.

I've included an INSTALL script that causes installation failure with an 
error message if the package version and OS_VERSION don't match.

The draft package to be imported as "pkgsrc/pkgtools/osabi" is attached as 
well as the bsd.pkg.mk/bsd.prefs.mk patch.

As for the three packages with OS_VERSION appended to there name:

* lsof          - I've got an update waiting, so can remove OS_VERSION then.

* x11-link      - Remove OS_VERSION and just update the version number to
                  0.48

* p5-perl-headers - I think this should just be left as is.

This is a dummy-package which is made a dependence for packages which are
tightly bound to a specific version of an operating system, e.g. LKMs or
sysutils/lsof. Such binary packages are not backwards compatible with other
versions of the OS.

The version number of this package should be similar to the operating system
version (`uname -r' output).
