Subject: [PATCH] BroadcastSystemMessage: - Implement User half only. -
 Introduce example use for NtUserMessageCall. - IntBroadcastSystemMessage is
 based on Wine LGPL implementation
 http://www.winehq.org/pipermail/wine-cvs/2008-April/042051.html . - Wine
 testing needed to be change by adding message range parameter check. The
 range was from 0 to -1 and check for resulting errors that conformed to XP. -
 Need to move BROADCASTPARM to include/X/X/ntuser.h or other after Dr. Timo
 finishes header realignment.
