[PATCH 2/3] remote: New function remote_is_configured()

[Finn Arne Gangstad <finnag@pvv.org>]

Previously, there was no beautiful way to check for the existence of
a configured remote. remote_get for example would always create the remote
"on demand".

This new function returns 1 if the remote is configured, 0 otherwise.
