Added client and server code for the GetPrintProcessorDirectory SPOOLSS

rpc.  This was supposed to fix a printer driver download bug but it didn't
but it seemed a shame to trash all this code so I'm commiting it #ifdef'ed
out in case someone needs it one day.
(This used to be commit bef43656471741c6c10b12e7516c15de9ae76394)
