For reftable development, it would be handy to have a tool to provide the
direct value of any ref whether it be a symbolic ref or not. Currently there
is git-symbolic-ref, which only works for symbolic refs, and git-rev-parse,
which will resolve the ref. Let's add a --symbolic-name option that will
print out the value the ref directly points to without dereferencing it.

Changes since V1:

 * changed output format to print out values as a third column
 * made plumbing changes to enable the value of a symbolic ref to be read
   from the iterator
 * changed the name of the flag

John Cai (3):
  refs: keep track of unresolved reference value in iterator
  refs: add referent to each_repo_ref_fn
  show-ref: add --symbolic-name option
