the bulk of the changes. Also split the loadparm related code into printing/load.c so swat can get it without linking to the backend code ------------ The following series of commits are for the new tdb based printing backend. This completely replaces our old printing backend. Major changes include: - all print ops are now done in printing/*.c rather than scattered all over the place - system job ids are decoupled from SMB job ids - the lpq parsers don't need to be nearly so smart, they only need to parse the filename, the status and system job id - we can store lots more info about a job, including the full job name - the queue cache control is much better I also added a new utility routine file_lines_load() that loads a text file and parses it into lines. This is used in out lpq parsing and I also want to use it to replace all of our fgets() based code in other places. (This used to be commit a902caf8d78ae4cb11ea3776d10273cb37d5fcd0)

printing: traverse_read the printer list for share updates The printcap update procedure involves the background printer process obtaining the printcap information from the printing backend, writing this to printer_list.tdb, and then notifying all smbd processes of the new list. The processes then all attempt to simultaneously traverse printer_list.tdb, in order to update their local share lists. With a large number of printers, and a large number of per-client smbd processes, this traversal results in significant lock contention, mostly due to the fact that the traversal is unnecessarily done with an exclusive (write) lock on the printer_list.tdb database. This commit changes the share update code path to perform a read-only traversal.
