If available, use DBus method MissingExecutables which finds executables
needed by new printer. This method is available in system-config-printer
since version 1.3.5 (#654742). User is offered installation of packages
containing those missing executables then.
If available, use DBus method GroupPhysicalDevices which removes duplicates
from list of found devices. This method is available in system-config-printer
since version 1.3.5 (#654742).
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).
This commit enables services mdns, ipp, ipp-client and samba-client on
firewall for 5 minutes for detection of network printers (#648784).
It enables required services permanently for printers selected by user
for addition then. It shows a notification for the permanent enable.
It uses firewalld, so if it is not installed or running it shows a warning
message to the user in the place where discovered printers will be shown
(both local and network). The warning disappears after the finish of
printers discovery (but not from network part if no printer was found).
Seeing as people were putting all kind of junk in it,
instead of being sensible, let's close the doors on
external panels.
If you work-around this in any way, you better have a
very good reason to, such as wanting to deny yourself
any support from the upstream gnome-control-center developers,
or wanting ridicule for your poor judgement in UI and code design.
So that it has more chances of fitting on a netbook screen. This is
done by removing the 6 pixel margin, and the 12 pixel bottom padding.
This gives us the whole panel with a height of around 550 pixels with
the default text size, which should be enough to display on a 600 pixels
high screen.

tz_info_from_location() was changing the value of TZ, but not
restoring it when it was done checking data for it, and setting
the GMT timezone instead.
This meant that UTC time was displayed when the minute changed on
the wall clock.
