[Xen-devel] [OSSTEST PATCH] Executive: Abolish use of the `configdb'

[Ian Jackson]

This was a database used by networking infrastructure on the
now-obsolete XenClient network in the Citrix Cambridge office (which
used some management tools developed by Mythic Beasts).

The production database in Cambridge no longer has the configdb, and
both instances have `HostDB_Executive_NoConfigDB 1' in the
configuration.  We think it very unlikely that anyone has as similar
arrangement.

Remove all the code for accessing this database.  We leave the config
settings `NoConfigDB' for now, for the benefit of ad-hoc trees which
are not immediately updated but which use their site's official
production-config.  They can be deleted later.
