Using back-config to update bdb DB_CONFIG parameters has problems.

Changing the parameters with back-config does work, and writes out a new
DB_CONFIG file, but a database reopen doesn't occur and therefore the
environment is not rebuilt. Furthermore, if one restarts slapd, a checkpoint
occurs, which in turn causes mtimes to change in the database and so the
rebuild-env-on-dbopen step isn't triggered.

The proper sequence should be:

close the db
write the new DB_CONFIG
open the db

The checkpoint will take place before DB_CONFIG is written, and on reopen, the
environment will be rebuilt.
