Pointers to general data should usually be used as a void pointer such that it is possible to hand in variables of a different pointer type without the need to cast. This is the same when creating patches from buffers, where the buffers may contain arbitrary data. Instead of requiring the caller to care whether his buffer is e.g. `char *` or `unsigned char *`, we should instead just accept a `void *`. This is also consistent in how we tread other types like for example `git_blob`, which also just has a void pointer as its raw contents.
