Drop the <uapi/linux/types.h> includes now that <linux/types.h>
(tools/include/linux/types.h) has a definition for __aligned_le64, which
is needed by <linux/iommufd.h>.
Including <uapi/linux/types.h> is harmless but causes benign typedef
redefinitions. This is not a problem for VFIO selftests but becomes an
issue when the VFIO selftests library is built into KVM selftests, since
they are built with -std=gnu99 which does not allow typedef redifitions.
No functional change intended.

Rename vfio_util.h to libvfio.h to match the name of libvfio.mk.

Drop the struct vfio_pci_device wrappers for IOMMU map/unmap functions
and require tests to directly call iommu_map(), iommu_unmap(), etc. This
results in more concise code, and also makes it clear the map operations
are happening on a struct iommu, not necessarily on a specific device,
especially when multi-device tests are introduced.
Do the same for iova_allocator_init() as that function only needs the
struct iommu, not struct vfio_pci_device.

Move the IOVA allocator into its own file, to provide better separation
between the allocator and the struct vfio_pci_device helper code.
The allocator could go into iommu.c, but it is standalone enough that a
separate file seems cleaner. This also continues the trend of having a
.c for every major object in VFIO selftests (vfio_pci_device.c,
vfio_pci_driver.c, iommu.c, and now iova_allocator.c).
No functional change intended.
