Add class PpSamba which contains asynchronous function
for searching for samba-shared printers. It can search
for printers on local network or on a specific host if
needed.

This commit adds PpHost object which represents a remote
host from which we want to get printers. It contains
asynchronous method for enumerating printers list from the host
using CUPS' SNMP backend and method for enumerating printers list
directly from the remote CUPS server running on the host. (#683229)
This commit adds asynchronous function get_cups_devices_async() which
sequentially executes CUPS' backends and returns found devices
by a callback. (#683229)
<cups/cups.h> has to be included in pp-utils.h because there
are functions in pp-utils.h which accepts types defined
in the cups.h as their parameters. (#683229)
This commit places list of jobs to separate dialog. The dialog
is updated through calling of pp_jobs_dialog_update()
from "Printers" panel because the panel is already subscribed
to cups notifications.
Add Options dialog which allows users to set more options than current dialog.
The dialog reads printer's PPD file and add its options to the dialog together
with some preselected IPP options (#678637).
All operations in the dialog are asynchronous.
During implementation of this, the option for setting allowed users was removed
because this is not suitable for this panel (the option is intended for
administrators).
This commit adds popup window which when activated allows
user to select PPD from local database of installed PPDs,
select directly PPD from filesystem or select one from 3
recommended PPDs (#678637).
The popup is activated by clicking on model field (the panel
has to be unlocked). It starts to search for the best PPDs
available immediately after its popup.
All operations are asynchronous.
Use new cups-pk-helper's method PrinterAddOption for setting
default media size for new printers. This fixes problem with
setting default media size (#672694).
Show correct hostname for each remote printer. G-c-c gets
it from printer-uri-supported or from device-uri CUPS options now.
It also set 'printer-network' icon for remote printers to have them
easily recognizable from local printers.
If available, use DBus method GetBestDriver which determines the best PPD file
for the given printer. This method is available in system-config-printer
since version 1.3.5 (#654742).
Clean "~/.cups/lpoptions" file before setting default printer
on local CUPS server. Store default printer to "~/.cups/lpoptions"
if we are connected to a remote CUPS server (#646100).
This patch makes Printers panel to automatically refresh printers list
when a new printer is added or removed. It is refreshed also when a printer
changes its state (to see changes in paused/unpaused state) (rhbz#691718).
It also automatically refresh list of jobs (and also number of active jobs in
main tab) for actual printer (rhbz#691737).
The dialog is able to add printers discovered by cupsGetDevices().
It can also add printers from a remote CUPS server by typing
its address and selecting printer we want to add (#640734).
