RFC: FreeBSD DB Port Reform

[Oliver Eikemeier]

You still don't address the problem that PREFIX/BerkeleyDB.N.M violates
hier(7), see also:

   http://www.freebsd.org/doc/en_US.ISO8859-1/books/porters-handbook/dads-subdirs.html

And, could you name a sample port that would benefit from the changes, i.e.
post a sample patch for net/openldap22-server or whatever port you like to
demonstrate the improvements.
