winspool: use printmonitors to manage the Ports

[Detlef Riekenberg]

Hi.

Printing in wine use gdi32.dll, gdi.exe, winspool.drv and wineps.drv as
Printer-Driver with CUPS/LPR as backend.

Many things are not correct (See: http://wiki.winehq.org/Printing ).

After some Patches, Wine is able to manage Printmonitors.

With the current work, a framework is added and wine start to use the
Printmonitors to manage the Printerports.
(Patch for wine-0.9.18, should also work for current HEAD)

I used various monitors for testing:
1: redmonnt.dll from RedMon 1.7
2: pdfcmnnt.dll from PDFCreator 0.9.2
3: localspl.dll from w2ksp4
4: a partial portmonitor for local Ports, added to winspool.drv

You can use a native printui.dll and play with the "Ports"-Page 
  wine rundll32.exe printui.dll,PrintUIEntry /s

Some notes about the Patch.
- FAR is used in "ddk/winsplp.h", but this does not work with wine.
  I removed that Keyword, but it is still present in the w2k3ddk
  An alternative would be "#define FAR" and "#undef FAR" around
  '#include "ddk/winsplp.h"' in "dlls/winspool.drv/info.c".
  Another Idea?

- The Spooler-Configuration was still using the Path from the old
  config - File. (Software\Wine\Wine\Config\Spooler<Portname>)
  Do we still need this? (A clean way is a seperate Portmonitor)

- native localspl.dll need a vailid Section [Ports] in "win.ini"
  to load. (I used "FILE:=" and "LPT1:=" as entries)

- Only Portmonitors, that use "InitializePrintMonitor" are supported.
  "InitializePrintMonitorUI" requires a "InitializePrintMonitor2" to
  be implemented, but this is a later step.

- AddPort/ConfigurePort/DeletePort in localspl.dll need support for
  "InitializePrintMonitor2" and all around XcvData.

- AddPort/ConfigurePort/DeletePort in the internal Portmonitor is not
  complete. (As Example, I simple reuse the "Save to File" - Dialog)

- The codebase for winspool.drv is really large (>240k) and I want to
  split the source. The correct way is creating "localspl.dll" for the
  local Portmonitor (as w2k and above) and another dll for the CUPS/LPR
  - Handling (and maybe Software\Wine\Wine\Config\Spooler<Portname>).
  A different fast hack is simple a new sourcefile for "winspool.drv"
  for a CUPS/LPR-Monitor and a local Portmonitor.

- the internal Portmonitor uses the Registry, where the Ports - Section
  from "win.ini" is redirected by "IniFileMapping" on windows.

- The Ports for the used CUPS/LPR - Printers is a later issue, when
  wine starts to use the managed Ports.

Please try this Patch and point your Ideas and Hints here, so I can
split the code into a set of Patches that can go clean into the Tree.

Thanks to all for your Help
