vc-log-outgoing fixes for git; add binding to vc-dir

* lisp/vc/vc-dir.el (vc-dir-mode-map): Bind "O" to vc-log-outgoing.
* lisp/vc/vc-git.el (vc-git-log-outgoing, vc-git-log-incoming): Use
async execution.
(vc-git-log-view-mode): Also truncate lines for log-outgoing and
log-incoming.
* lisp/vc/vc.el (vc-log-incoming, vc-log-outgoing): Don't pass nil
as remote-location argument.
