branch: roll show_detached HEAD into regular ref_list
Remove show_detached() and make detached HEAD to be rolled into
regular ref_list by adding REF_DETACHED_HEAD as a kind of branch and
supporting the same in append_ref(). This eliminates the need for an
extra function and helps in easier porting of branch.c to use
ref-filter APIs.
Before show_detached() used to check if the HEAD branch satisfies the
'--contains' option, now that is taken care by append_ref().
