Revised handling of append/remove upcalls: Closes bgno#721326

This approach immediately updates the remote_count when an upcall
is received, as that math is important for determining positional
addressing if another one immediately follows it.  However, the
async calls only deal in the remote count *at the time the upcall
arrived*, in effect allowing for the upcall to be serially processed
using async blocking calls.
Clean up the password dialog

* Remove details section
* Fix plural problem
* Remove unnecessary labels
* Only allow to prompt for one password at a time, which was true in
  practice already, but the code is cleaner making that a requirement
