vhost-user: add blk device support

Browse Source 
Introduce basic vhost-user-blk-pci support.

In adding this, cleaned up the QemuParams function to use a more
appropriate switch statement.  Similarly, cleanup up the Valid() logic.

We still need to look into parameterization of the block parameter
fields as well as introducing multiqueue support for the vhost-user devices.
