This creates remotes.[ch], which implement for_each_remote, a function
for enumerating all remotes.

I wrote this to play with Carl's "look for branches under refs/remotes/"
idea. Since these functions have no users, I don't know if it's worth
applying this patch. However, I thought I would publish it, at least,
since it may eventually become useful.
