buffer: return errors for `git_buf_init` and `git_buf_attach` Both the `git_buf_init` and `git_buf_attach` functions may call `git_buf_grow` in case they were given an allocation length as parameter. As such, it is possible for these functions to fail when we run out of memory. While it won't probably be used anytime soon, it does indeed make sense to also record this fact by returning an error code from both functions. As they belong to the internal API only, this change does not break our interface.
