[PATCHv2 5/5] builtin-remote: Make "remote -v" display push urls

[Michael J Gruber <git@drmicha.warpmail.net>]

Currently, "remote -v" simply lists all urls so that one has to remember
that only the first one is used for fetches, and all are used for
pushes.

Change this so that the role of an url is displayed in parentheses, and
also display push urls.

Example with "one" having one url, "two" two urls, "three" one url and
one pushurl:

one     hostone.com:/somepath/repoone.git (fetch)
one     hostone.com:/somepath/repoone.git (push)
three   http://hostthree.com/otherpath/repothree.git (fetch)
three   hostthree.com:/pathforpushes/repothree.git (push)
two     hosttwo.com:/somepath/repotwo.git (fetch)
two     hosttwo.com:/somepath/repotwo.git (push)
two     hosttwobackup.com:/somewheresafe/repotwo.git (push)
