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.
