remote.c: introduce remote.pushdefault

This new configuration variable defines the default remote to push to,
and overrides `branch.<name>.remote` for all branches.  It is useful
in the typical triangular-workflow setup, where the remote you're
fetching from is different from the remote you're pushing to.
