This also changes the frontend to use this interface. This will be a bit less efficient in the general case, as it will serialize the PaperList and DefaultSettings fetches. But most of the large delays seem to occur when the print server is slow to respond, and ultimately using a single live connection for both these requests when possible (particularly with CUPS) should improve the total latency when the printer or print server is not available, or is very slow.
