Log message:
Rework the Berkeley DB detection in buildlink3:

  * Add a db1.builtin.mk file that detects whether DB-1.85 functionality
    exists in the base system, and remove the distinction between
    "native" and the other Berkeley DB packages -- we now refer to
    db[1234].  This paves the way for any future databases/db1 package.

  * USE_DB185 shouldn't need to be set by any packages -- its correct
    value is now automatically determined by bdb.buildlink3.mk depending
    on whether we explicitly request db1 or not.  By default, if you
    include bdb.buildlink3.mk, you want DB-1.85 functionality and
    USE_DB185 defaults to "yes", but if you explicitly remove db1 from
    the list of acceptable DBs, then USE_DB185 defaults to "no".

  * Set BDB_LIBS to the library options needed to link against the DB
    library when bdb.buildlink3.mk is included.

  * We only add the DB library to the linker command automatically if
    we want DB-1.85 functionality; otherwise assume that the package
    configure process can figure out how to probe for the correct
    headers and libraries.

Edit package Makefiles to nuke redundant settings of USE_DB185.

Log message:
Fix error in previous... BDB_ACCEPTED needs to be defined before including
bdb.buildlink3.mk.

Log message:
Refer to the Berkeley DB libraries using ${BDB_TYPE} instead of db2.
This has no effect, but makes maintenance easier if we ever add to
BDB_ACCEPTED in this Makefile.

Log message:
More accurately follow template package Makefile.

Log message:
add optional db2 support via PKG_OPTIONS.cucipop=db2. fix some bugs in
db2 code using hints from debian's fix.

makevpopdb works now, but there are still bugs lurking in the virtual
domain code.

no PKGREVISION bump as db2 is not enabled by default.
