[STR New]

Wine ( http://www.winehq.org ) must present available Printers
and the default Printer to Windows Applications.

To make sure, that the list is up to Date, the current Code call
cupsGetDests(), when an Application is started.
This is a lot of overhead and need ages (minutes with 50 Network
Printers), until the Application comes up.

Checking /etc/printcap does not work on all Systems due to the option
Printcap without a filename.

An cups-API, that return a checksum (md5sum / crc32) or a
modification-time for the default Printer and all available Printers
is a big enhancement for Wine.
This Feature can also reduce the Network-Traffic for CUPS, when
cups_dest_t is cached inside CUPS.

Thanks
