We already supported getting driver info level 8 but not adding it. This
allows adding printer drivers with level. So several fields where emtpy.
Microsoft released a security update for Windows print spooler
components which requires support for driver info level 8 now. This is
needed to find out if a driver is PACKAGE_AWARE or not.

The printcap housekeeping callback is scheduled to run every 60 seconds,
and invokes pcap_cache_reload() to reload of the printcap cache *if* the
"printcap cache time" period has expired.
Given that pcap_cache_reload() invocation is the only job of the
housekeeping callback, it makes much more sense to schedule it every
"printcap cache time" seconds, rather than every 60 seconds.

The CUPS IPP_GET_JOBS requested-attributes array indicates which job
attributes the caller would like in the cupsd response.
Until now, Samba has packed these attributes with a IPP_TAG_NAME
format tag. In recent versions of CUPS, this results in the IPP_GET_JOBS
response only including the job-id and job-printer-uri fields, even with
JobPrivateValues=none configured.

Samba needs to deal with two types of print job identifiers, those
allocated by the printing backend (sysjob ids), and those allocated
by Samba's spoolss server (jobids).
This change adds a helper function to map spoolss jobids to sysjob ids,
to go alongside the corresponding sysjob to jobid mapping function.

All printer inventory updates are currently done via
delete_and_reload_printers(), which handles registry.tdb updates for
added or removed printers, AD printer unpublishing on removal, as well
as share service creation and deletion.
This change splits this functionality into two functions such that
per-client smbd processes do not perform registry.tdb updates or printer
unpublishing. This is now only performed by the process that performs
the printcap cache update.
This change is similar to ac6604868d from
the 3.6 branch.

Currently, automatic printer share updates are handled in the following
way:
- Background printer process (BPP) forked on startup
- Parent smbd and per-client children await MSG_PRINTER_PCAP messages
- BPP periodically polls the printing backend for printcap data
- printcap data written to printer_list.tdb
- MSG_PRINTER_PCAP sent to all smbd processes following update
- smbd processes all read the latest printer_list.tdb data, and update
their share listings
This procedure is not scalable, as all smbd processes hit
printer_list.tdb in parallel, resulting in a large spike in CPU usage.
This change sees smbd processes only update their printer share lists
only when a client asks for this information, e.g. via NetShareEnum or
EnumPrinters.

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.
