object: implement function to parse raw data

Now that we have implement functions to parse all git objects from raw
data, we can implement a generic function `git_object__from_raw` to
create a structure of type `git_object`. This allows us to parse and
interpret objects from raw data without having to touch the ODB at all,
which is especially useful for object verification prior to accepting
them into the repository.
