Michael Haggerty 42a38cf788 read_raw_ref(): manage own scratch space ... Instead of creating scratch space in resolve_ref_unsafe() and passing it down through resolve_ref_1 to read_raw_ref(), teach read_raw_ref() to manage its own scratch space. This reduces coupling across the functions at the cost of some extra allocations. Also, when read_raw_ref() is implemented for different reference backends, the other implementations might have different scratch space requirements. Note that we now preserve errno across the calls to strbuf_release(), which calls free() and can thus theoretically overwrite errno.
