[PATCH 0/5] cleanup interfaces

[Zhenzhong Duan <zhenzhong.duan@intel.com>]

Hi,

This series addresses Cédric's suggestion[1] and Donald's suggestion[2] to
move realize() call after attach_device().

Also addresses Eric and Nicolin's suggestion[3] to use a union to hold different
vendor capabilities.

Test:
net card passthrough and ping test
hotplug/unplug

Based on vfio-next(b9d42a878b).

Thanks
