Use g_steal_pointer() on task in get_bus_cb() in pp-printer.c
to not invalidate a pointer passed to a DBus call.
Cleanup the task in callback of the DBus call.
The previous code was leaking a string (job title), used an integer pointer
instead of an integer for an id and requited a lot of memory management for a
string array. There was a lot of boilerplate code required for property
management which was not being used much. This is why type safe methods are a
much better idea than GObject properties. :)
Get "job-hold-until" attribute when getting list of jobs. If it has value
"auth-info-required" then get "auth-info-required" attribute of the printer
and store it in PpJob's "auth-info-required" property.

This changes are necessary because we don't require cups >= 1.4,
due to downstreams still shipping old cups versions.
The IPP_STATE_IDLE symbol has been introduced in cups 1.7. The
IPP_IDLE constant has been deprecated.

pp_printer_rename_async is better than the old printer_rename
utility.
The PpDetailsDialog doesn't need to do anything in the callback
since we are emiting the "printer-changed" signal when the dialog
is closed.
