[PATCH v3 0/4] libxl: add HVM USB passthrough capability

[Juergen Gross <jgross@suse.com>]

Add the capability to pass USB devices to HVM domains by using the
emulation of USB controllers of qemu.

The user interface via xl is the same as for pvusb passthrough, only
the type of the usbctrl is different: instead of "qusb" (qemu-based
pvusb backend) or "vusb" (kernel-based pvusb backend) the type
"devicemodel" is used.

Especially the communication with qemu via qmp commands is based on
the patches of George Dunlap sent in 2014:

Changes in V3:
- patch 3: rename pvusb_get_port_path() to vusb_get_port_path()
  as requested by George Dunlap
- patch 4: wording adjusted as requested by Ian Jackson

Changes in V2:
- patches 1-3 removed as already pushed
- split out (new) patch 1 from patch 3 (was 5) as requested by Wei Liu
- addressed code style issues in patch 3 (was 5) as requested by Wei Liu
- added some assert()s n patch 3 (was 5) as requested by Wei Liu
