Directly run a diff between two buffers.
Even more than with git_diff_blobs, comparing two buffer lacks
context, so the git_diff_file parameters to the callbacks will be
faked a la the rules for git_diff_blobs().
int git_diff_buffers(const void *old_buffer, size_t old_len, const char *old_as_path, const void *new_buffer, size_t new_len, const char *new_as_path, const git_diff_options *options, git_diff_file_cb file_cb, git_diff_binary_cb binary_cb, git_diff_hunk_cb hunk_cb, git_diff_line_cb line_cb, void *payload);
