New output style for git remote show

Junio, this is based on pu, as it builds on my and Jeff's git remote changes. Patches 1-7 are about new output style for "git remote show" for everything but the push refspecs. Patches 8-13 then culiminate in teaching it a new output style for push refspecs as well.

1-4 were previously a single patch which I broke up per your feedback (gmane 110806).

Jay Soffian (13):
remote: rename variable and eliminate redundant function call
remote: remove unused code in get_ref_states
remote: fix two inconsistencies in the output of "show <remote>"
remote: make get_remote_ref_states() always populate states.tracked
remote: name remote_refs consistently
string-list: new for_each_string_list() function
remote: new show output style
refactor duplicated get_local_heads() to remote.c
refactor duplicated ref_newer() to remote.c
remote.c: make match_refs() copy src ref before assigning to peer_ref remote.c: don't short-circuit match_refs() when error in
match_explicit_refs()
remote.c: refactor get_remote_ref_states()
remote: new show output style for push refspecs
