vfio_get_device now takes a VFIODevice as argument. The function is split
into 2 parts: vfio_get_device which is generic and vfio_populate_device
which is bus specific.
3 new fields are introduced in VFIODevice to store dev_info.
vfio_put_base_device is created.

This structure is going to be shared by VFIOPCIDevice and
VFIOPlatformDevice. VFIOBAR includes it.
vfio_eoi becomes an ops of VFIODevice specialized by parent device.
This makes possible to transform vfio_bar_write/read into generic
vfio_region_write/read that will be used by VFIOPlatformDevice too.
vfio_mmap_bar becomes vfio_map_region

Since we can potentially have both PCI and platform devices in
the same VFIO group, this latter now owns a list of VFIODevices.
A unified reset handler, vfio_reset_handler, is registered, looping
through this VFIODevice list. 2 specialized operations are introduced
(vfio_compute_needs_reset and vfio_hot_reset_multi): they allow to
implement type specific behavior. also reset_works and needs_reset
VFIOPCIDevice fields are moved into VFIODevice.

Add 3 new fields in the VFIODevice struct. Type is set to
VFIO_DEVICE_TYPE_PCI. The type enum value will later be used
to discriminate between VFIO PCI and platform devices. The name is
set to domain:bus:slot:function. Currently used to test whether
the device already is attached to the group. Later on, the name
will be used to simplify all traces. The group is simply moved
from VFIOPCIDevice to VFIODevice.

Introduce a new base VFIODevice strcut that will be used by both PCI
and Platform VFIO device. Move VFIOPCIDevice fd field there. Obviously
other fields from VFIOPCIDevice will be moved there but this patch
file is introduced to ease the review.
Also vfio_mask_single_irqindex, vfio_unmask_single_irqindex,
vfio_disable_irqindex now take a VFIODevice handle as argument.

To prepare for platform device introduction, rename vfio_mask_intx
and vfio_unmask_intx into vfio_mask_single_irqindex and respectively
unmask_single_irqindex. Also use a nex index parameter.
With that name and prototype the function will be usable for other
indexes than VFIO_PCI_INTX_IRQ_INDEX.
