[PATCH v10 0/2] MR6904: ntdll.dll: Update NtQueryDirectoryFile to align with current Windows behaviour
This PR updates the behaviour of `NtQueryDirectoryFile`, bringing it in line with current Windows behaviour. The need for this update was discovered when attempting to build the Unreal Engine with MSVC under Wine. In certain cases conditional include statements do not behave as expected, due to MSVC depending on undocumented behaviour of `NtQueryDirectoryFile`.
We ran tests on multiple versions of Windows, and discovered that the behaviour has changed since the original Wine implementation, but the documentation has not. The source code for our test tool, and a set of results can be found [here](https://github.com/TensorWorks/NtQueryDirectoryFile-Test). As of Windows 8, calling `NtQueryDirectoryFile` with a re-used handle, a new mask, and setting the `RestartScan` flag to True, causes the cached results to be erased and a new scan to be performed with the updated mask. Currently, Wine performs as did earlier versions of Windows, where the changed mask is ignored, and the cache is reused. This can cause `NtQueryDirectoryFile` under Wine to falsely report that files exist, when they do not.
This PR corrects this behaviour, invalidating the cache when required. Implementing this exposed further undocumented behaviour of `NtQueryDirectoryFile`, where a search for a non-existent file will return either `STATUS_NO_MORE_FILES` or `STATUS_NO_SUCH_FILE`, depending on whether or not the handle had been previously used regardless of the value of `RestartScan`. This was reflected in a `winetest` which allowed for the response to be either `STATUS_SUCCESS` or `STATUS_NO_MORE_FILES`.
This patch also adds unit tests for the new behaviour of `NtQueryDirectoryFile`. These tests pass when running `winetest` under Windows, and under Wine with these changes in place, but they will fail under older versions of Wine. If run under older versions of Windows the test suite will detect that this functionality is not supported, and will not run the updated tests.

Hi,
It looks like your patch introduced the new failures shown below. Please investigate and fix them before resubmitting your patch. If they are not new, fixing them anyway would help a lot. Otherwise please ask for the known failures list to be updated.
The tests also ran into some preexisting test failures. If you know how to fix them that would be helpful. See the TestBot job for the details:
The full results can be found at: https://testbot.winehq.org/JobDetails.pl?Key=151153
Your paranoid android.

thanks for all the effort... looks good to me
one last nitpick: it really looks like NULL mask or mask with 0 length are treated the same way, so this could be factorized further like in the attached patch so that one no longer needs to take care of 0 length masks
