Log Message:
Modify bdb.buildlink3.mk so that we choose a single, well-known package
for all Berkeley DB dependencies instead of choosing the best installed
DB package by default:

1. BDB_DEFAULT is set in /etc/mk.conf for the life of pkgsrc and
   represents the package we use when either (1) a db-1.85 interface
   isn't required, or (2) a db-1.85 interface *is* required, but it's
   not builtin.  It defaults to "db4" but can be any of db[234].

2. BDB185_DEFAULT is set in /etc/mk.conf for the life of pkgsrc and
   represents the package we use when a db-1.85 interface is required.
   It defaults to "db1" if it's builtin, or to ${BDB_DEFAULT}
   otherwise.[**]

3. If we want db1, then we use the package named in BDB185_DEFAULT.
   If we don't want db1, then we use the package named in BDB_DEFAULT.

4. If ${BDB_DEFAULT} isn't listed in BDB_ACCEPTED for a package, then
   that package will be marked with PKG_FAIL_REASON as "${BDB_DEFAULT}
   not a supported Berkeley DB type for ${PKGNAME}."

Using the above scheme, on NetBSD, the default of BDB_DEFAULT=db4 and
BDB185_DEFAULT=db1 will cause db1 to be used whenever we want a db-1.85
interface and db4 to be used for all other packages.
