Changes from APPLIANCE_HEAD (per Tim Potter):

	- make proto
	- addition of function to convert from errno values to NT status codes
	  (source/lib/error.c)
	- purge queue done without full access permission will purge only the
	  jobs owned by that user, rather than failing.
	- unlock job database tdb before sending job to printer
	- in print_job_start(), ensure that we don't pick a jobid with an existing
	  temporary file that may be owned by another user, as it causes silent
	  failures.
	- fixes for printer permission checking for NT5 clients
	  (source/include/rpc_spoolss.h, source/printing/nt_printing.c,
	   source/printing/printing.c, source/rpc_server/srv_spoolss_nt.c)
	- change from uint8 to 'enum SID_NAME_USE' (source/rpc_server/srv_lsa.c)
	- fixed memory leaks for win95 driver download process
	  (source/smbd/lanman.c)
	- properly free prs_structs and dacl in testsuite/printing/psec.c
(This used to be commit 74af3e2caec7197e5d1ca389e2f78054a4197502)
