From: Jeff Cody <jcody@redhat.com>

This adds configure options to control the following block drivers:

* Bochs
* Cloop
* Dmg
* Qcow (V1)
* Vdi
* Vvfat
* qed
* parallels
* sheepdog

Each of these defaults to being enabled.

Hmm, we got quite a few --enable-BLOCK-DRIVER now.  Perhaps a single
list-valued option similar --target-list would be better.  Could be
done on top.
