cups-filters 1.21.6 released!

[Till Kamppeter <till.kamppeter@gmail.com>]

Hi,

I have released cups-filters 1.21.6 now, with the following changes:

	- cups-browsed: To find out whether a DNS-SD-discovered
	  printer is from the local machine, use not only the flags in
	  the Avahi lookup result but also check the host name.
	- cups-browsed: When a local CUPS queue pointing to a remote
	  CUPS printer was removed and re-created to make it a
	  permanent queue, on_printer_deleted() was triggered by
	  cupsd's notification to re-create a lost queue. Now
	  on_printer_deleted() checks whether the queue is really gone
	  and only re-creates then (Issue #80).
	- cups-browsed: When updating the CUPS queues, also removed
	  and unregistered queues and not only created queues got
	  checked for HTTP timeouts, which caused crashes on shutdown
	  (Issue #79, Debian bug #916149).
	- pdftops: Use the PS interpreter of Poppler for all Apple
	  LaserWriter 16/600, 4/600, 12/640, 12/600, 12/660 as they
	  all seem to not work with Ghostscript's PS output (Issue
	  #76).
	- cups-browsed: On shutdown queues got removed even if they
	  still had jobs (Debian bug #908147).

Bug fix release, mainly for cups-browsed to avoid crashes and infinite 
printer removal/re-creation loops and spurious local queues for local 
CUPS printers. Also expanded PostScript interpreter bug workaround to 
more Apple LaserWriter models.

Please release this on Debian so that it syncs into Ubuntu.

Thanks in advance.
