[Ovirt-devel] Various API patches

[David Lutterkort]

This series of patches makes various changes needed for the API and the
command line client. In detail, they do:

1/8: small bugfix
2/8: remove the client/ directory; everything there will go into a new
     ovirt-client git repo. I'll send out patches for that shortly
3/8 and 4/8: add additional info to the XML available through the API
5/8 and 6/8: Create a new StorageVolumeController and move handling of storage
     volumes out of the StorageController. Remove dead code
7/8: report an error with a human-readable error message through the API (yay)
8/8: route API calls for storage volumes

The main patch of this series is 5/8, the others are all pretty trivial.
