[ion at svn.reactos.org]

- Invert CONFIG_SMP defines as requested by Hartmut
- Remove KiBlockThread and replace by more elegant KiSwapThread which will also make moving to the new scheduler easier.
- Handle special case where we have kernel apcs pending and your previous irql was below apc_level during the wait code.
- Remove hack to manually unwait a thread during a status of kernel apc.
