vfio: Convert type1 iommu to use rbtree
We need to keep track of all the DMA mappings of an iommu container so that it can be automatically unmapped when the user releases the file descriptor. We currently do this using a simple list, where we merge entries with contiguous iovas and virtual addresses. Using a tree for this is a bit more efficient and allows us to use common code instead of inventing our own. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>
