[ros-diffs] [ion] 25586: - Implement new ExHandle* implementation using pushlocks and the Windows 2003 HANDLE_TABLE structure and semantics. Only the currently used base APIs were implemented; support for audit masks still disabled, debug/tracing calls disabled. - Remove manual overrides of NTDDI_VERSION all over the thread and set it once globally, since ExHandle* was the only non-updated package. The entire kernel now builds with Windows 2003 SP1 as a target. - Remove this entry from kernel fun.
