* - If refname is the name of a normal reference, fill in sha1
* (leaving referent unchanged).
*
* - If refname is the name of a symbolic reference, write the full
* name of the reference to which it refers (e.g.
* "refs/heads/master") to referent and set the REF_ISSYMREF bit in
* type (leaving sha1 unchanged). The caller is responsible for
* validating that referent is a valid reference name.
*
* WARNING: refname might be used as part of a filename, so it is
* important from a security standpoint that it be safe in the sense
* of refname_is_safe(). Moreover, for symrefs this function sets
* referent to whatever the repository says, which might not be a
* properly-formatted or even safe reference name. NEITHER INPUT NOR
* OUTPUT REFERENCE NAMES ARE VALIDATED WITHIN THIS FUNCTION.
*
* Return 0 on success. If the ref doesn't exist, set errno to ENOENT
* and return -1. If the ref exists but is neither a symbolic ref nor
* a sha1, it is broken; set REF_ISBROKEN in type, set errno to
* EINVAL, and return -1. If there is another error reading the ref,
* set errno appropriately and return -1.
*
* Backend-specific flags might be set in type as well, regardless of
* outcome.
*
* It is OK for refname to point into referent. If so:
*
* - if the function succeeds with REF_ISSYMREF, referent will be
* overwritten and the memory formerly pointed to by it might be
* changed or even freed.
*
* - in all other cases, referent will be untouched, and therefore
* refname will still be valid and unchanged.
