Colin Finck aa84b232e5 [LOCALSPL_APITEST]
Add a test for fpGetPrintProcessorDirectory, the actual worker function inside localspl.dll at the end of the call chain.
With that final test, we should have enough information to implement 100% compatible versions of GetPrintProcessorDirectoryA/W and fpGetPrintProcessorDirectory.

[WINSPOOL_APITEST]
Initialize some more variables with bogus values to verify that they have actually changed.

Next step for CORE-12399

/*
* The original localspl.dll from Windows Server 2003 is not easily testable.
* It relies on a proper initialization inside spoolsv.exe, so we can't just load it in an API-Test as usual.
* See https://www.reactos.org/pipermail/ros-dev/2015-June/017395.html for more information.
*
* To make testing possible anyway, this program basically does four things:
* - Injecting our testing code into spoolsv.exe.
* - Registering and running us as a service in the SYSTEM security context like spoolsv.exe, so that injection is possible at all.
* - Sending the test name and receiving the console output over named pipes.
* - Redirecting the received console output to stdout again, so it looks and feels like a standard API-Test.
*
* To simplify debugging of the injected code, it is entirely separated into a DLL file localspl_apitest.dll.
* What we actually inject is a LoadLibraryW call, so that the DLL is loaded gracefully without any hacks.
* Therefore, you can just attach your debugger to the spoolsv.exe process and set breakpoints on the localspl_apitest.dll code.
