  xdiff: upgrade to core git 2.4.5 Upgrade xdiff to version used in core git 2.4.5 (0df0541). Corrects an issue where an LF is added at EOF while applying an unrelated change (ba31180), cleans up some unused code (be89977 and e5b0662), and provides an improved callback to avoid leaking internal (to xdiff) structures (467d348). This also adds some additional functionality that we do not yet take advantage of, namely the ability to ignore changes whose lines are all blank (36617af).
