Add buffer to buffer diff and patch APIs This adds `git_diff_buffers` and `git_patch_from_buffers`. This also includes a bunch of internal refactoring to increase the shared code between these functions and the blob-to-blob and blob-to-buffer APIs, as well as some higher level assert helpers in the tests to also remove redundancy.
