Implement IsServerSideWindow function in user32. It checks whether a window has a window procedure that resides in kernel mode and returns a boolean condition based on the appropriate internal window state flag (WNDS_SERVERSIDEWINDOWPROC).
This function is not officially documented by Microsoft, but fortunately it has unofficial documentation at http://undoc.airesoft.co.uk/user32.dll/IsServerSideWindow.php.
Required and used internally by uxtheme.dll from Windows XP/2003/Vista/7/etc. The log spams with it a lot, when using uxtheme.dll from Windows in ReactOS.

CORE-11700
Need a way to send WM_DEVICECHANGE from the Service manager application.
Next step is to process it in the Client/Server Run-time Subsystem.
See CORE-16492.
This function is a condensed version of LpkPSMTextOut() (from lpk.dll),
but not bug-for-bug equivalent.
The main difference is that the underscore is drawn without taking into
account any kind of script processing.
