I know how to take an external project and merge it into MariaDB. This uses
the "merge-into" bzr plugin.

However, I do not know how to go in the opposite direction, that is take a
part od the MariaDB tree and split it out in a separate project, and still
allow merging it back in.

Unless we want to delete it from our tree, re-create as a separate project,
and merge that external project using merge-into. This would loose the
revision history (I think).

Also note that there seems to be a number of problems with this approach due
to this bug:


(For us, it works for xtradb, but not pbxt. Recently, some more people seem to
also be hit by this, including MySQL people.)
