	Update vfio_pci_bar_map() to align BAR mmaps for efficient huge page mappings. The manual mmap alignment can be removed once mmap(!MAP_FIXED) on vfio device fds improves to automatically return well-aligned addresses. Also add MADV_HUGEPAGE, which encourages the kernel to use huge pages (e.g. when /sys/kernel/mm/transparent_hugepage/enabled is set to "madvise"). Drop MAP_FILE from mmap(). It is an ignored compatibility flag.

2025-11-28	vfio: selftests: Move vfio_selftests_*() helpers into libvfio.c	David Matlack
	Move the vfio_selftests_*() helpers into their own file libvfio.c. These helpers have nothing to do with struct vfio_pci_device, so they don't make sense in vfio_pci_device.c. No functional change intended.
