Git.pm: Add remote_refs() git-ls-remote frontend
This patch also converts the good ole' git-remote.perl to use it. It is otherwise used in the repo.or.cz machinery and I guess other scripts might find it useful too. Unfortunately, git-ls-remote --heads . is subtly different from git-ls-remote . refs/heads/ (since the second matches anywhere in the string, not just at the beginning) so we have to provide interface for both.

+=item remote_refs ( REPOSITORY [, GROUPS [, REFGLOBS ] ] )
+
+This function returns a hashref of refs stored in a given remote repository.
+The hash is in the format C<refname =\> hash>. For tags, the C<refname> entry
+contains the tag object while a C<refname^{}> entry gives the tagged objects.
+
+C<REPOSITORY> has the same meaning as the appropriate C<git-ls-remote>
+argument; either an URL or a remote name (if called on a repository instance).
+C<GROUPS> is an optional arrayref that can contain 'tags' to return all the
+tags and/or 'heads' to return all the heads. C<REFGLOB> is an optional array
+of strings containing a shell-like glob to further limit the refs returned in
+the hash; the meaning is again the same as the appropriate C<git-ls-remote>
+argument.
+
+This function may or may not be called on a repository instance. In the former
+case, remote names as defined in the repository are recognized as repository
+specifiers.
