[PATCH v2 2/3] refs: add referent to each_repo_ref_fn

["John Cai via GitGitGadget" <gitgitgadget@gmail.com>]

From: John Cai <johncai86@gmail.com>

There is no way for callers of the refs api functions that use iterators
to get a hold of a direct value of a symbolic ref before its resolved in
the callback functions, as either each_ref_fn nor each_repo_ref_fn have
an argument for this.

This did not matter since the iterators did not hold onto the direct
value of a reference anyway. But, the previous commit started to save
the value of the direct reference in the iterator.

Add an argument to each_repo_ref_fn that gets passed the direct
value of a reference.
