[PATCH for-10.1 08/10] ui/vdagent: factor out clipboard peer registration

[marcandre . lureau]

From: Marc-André Lureau <marcandre.lur...@redhat.com>

This allows common code reuse during migration.

Note that resetting the serial is now done regardless if the clipboard
peer was registered or not. This should still be correct.
