* Per PR142, make task switch extension its own list.
	* include/rtems/score/userext.h: Reflect above by adding
	User_extensions_Switch_control and adding it to User_extenions_Control.
	* inline/rtems/score/userext.inl: Allocate all memory in one chunk
	to minimize overhead.  Address processing dedicated switch chain.
