xdiff: include new xdiff from git Update to the xdiff used in git v2.35.0, with updates to our build configuration to ignore the sort of warnings that we normally care about (signed/unsigned mismatch, unused, etc.) Any git-specific abstraction bits are now redefined for our use in `git-xdiff.h`. It is a (wildly optimistic) hope that we can use that indirection layer to standardize on a shared xdiff implementation.
