1e83435eac 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.

fe72740e82 loadparm: make the source3/ lp_ functions take an explicit TALLOC_CTX *.
They use talloc_tos() internally: hoist that up to the callers, some
of whom don't want to us talloc_tos().

A simple patch, but hits a lot of files.

This defines a common table format, so we can in future define a
common table.

04248c2cfa s3-printing: reload shares after pcap cache fill
Since commit eada8f8a, updates to the cups pcap cache are performed
asynchronously - cups_cache_reload() forks a child process to request
cups printer information and notify the parent smbd on completion.

Currently printer shares are reloaded immediately following the call to
cups_cache_reload(), this occurs prior to smbd receiving new cups pcap
information from the child process. Such behaviour can result in stale
print shares as outlined in bug 7836.

This fix ensures print shares are only reloaded after new pcap data has
been received.

eada8f8abe If you have a large number of cups printers, then scanning for print info can cause a client to timeout
(it takes longer than 30 seconds to enumerate them). Make scanning for printers async with a callback
from the main loop. This fixes a bug that was irritating *me* :-).

792ca5d989 Changes from APPLIANCE_HEAD:
source/rpc_server/srv_spoolss_nt.c
        - Unrolled construct_notify_jobs_info() loop to only fetch
          printer info_2 structure once rather than num_print_jobs times.
        - convert command to unix codepage.
        - remove lp_remove_service() call as it prevents lp_killservice()
          from working.
        - Modified some DEBUG and DEBUGADD statements.

    source/param/loadparm.c
    source/param/params.c
        - change printer, preload, auto services to FLAG_DOS_STRING,
          reverted earlier changes to szPrintername et al, add comments.

    source/printing/load.c
        - fix bug with lp_auto_services() and strtok()

    source/printing/nt_printing.c
    source/printing/printing.c
        - remove redundant test that used SERVICE(snum)

    source/printing/pcap.c
        - add unix_to_dos() calls, add notes wrt FIXMEs for
          xxx_printer_fn() functions.

    source/web/swat.c
        - added FIXME comment.

    source/smbd/service.c
        - added comment re: dos codepage

49fcb300de Added John Reilly's enumports/addprinter/delprinter scripting code plus the
fix for the Win9x printer drivers.
Changed command names to add "command" string on the end for some consistancy
with the other scripting commands.
Added '%P' option to tdbpack/unpack to store long comment string.
Made port name be "Samba Printer Port" if no enum port script given.
Fixed prs_uint32_pre code to cope with null args.

5711f1f196 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.
