    Add a 'store_in_cache' attribute to the DownloadPackages method

    This is so we know whether to copy them into a new directory, or
leave them in
    the package manager cache.

    Note: this does not change the API of the client libraries as we
can test if the
    download directory is not NULL and set the boolean value accordingly.

Daniel is fixing up packagekit-qt now, and client programs shouldn't
be affected at all. The purpose of the patch is to allow client
programs such as gnome-shell to download the pending updates in the
user session, and then for system programs like systemd to install the
updates when then user shuts down. Do do this, we need to store the
packages in the system package cache rather than copy them into
/var/lib/PackageKit like we normally do.

If you're maintaining a backend, please make sure that it accepts NULL
as a directory value for DownloadPackages. If NULL, just download to
the system package cache like normal, and you don't need to emit
::Files() either (but if you do, it's ignored).

If you find the downloading stuff complicated, just see
