1) Updated KUSER_SHARED_DATA to NT5+ exported documented defintiion, which meant the removal of DosDevices. Used proper NT _DEVICE_MAP Structure for this, but did it in a "hack" way, ie, not a fully implementation, but enough to keep the basic old functionality as before. This will need an review once the Ob Manager is overhaulted. Modified kernel32 to request the _DEVICE_MAP for the current process, implemented the query routine (but made it return the default systme device map intead of per process) and changed the kernel code to use the default device map instead.

2) Updated the HalDispatchTable to Version 3.0. Not a huge change, just added/updated some functions.
3) Rewrote most of the DPC Code to take advantage of the CPU/Importance "laws". Stress testing on my machine revealed no issues on CVS HEAD. Still needs some review to make it so that idle threads can call dpcs (so that low importance dpcs will be dispatched by the idle thread). I will modify this later.
