Ray Strode e9a3329054 - Fix user list async bugs by dropping async code and 
moving to accounts service library
  Resolves: #678236
- Add requires for accounts service to spec since it isn't
  optional (and hasn't been for a while)

Subject: [PATCH 1/2] greeter: fix swapped LHS/RHS in icon loading error path
This nasty bug means in some obscure cases we're going to
end up using freed memory.

Subject: [PATCH 2/2] greeter: port to account service library
The current user manager code is a mess of dbus code for
talking to the accounts daemon and code for falling back if
it isn't there. The accounts daemon is no longer optional,
so drop all that and just use the accounts service library
directly.
