	* sapi/include/rtems/init.h, sapi/src/exinit.c: Refactored and renamed
	initialization routines to rtems_initialize_data_structures,
	rtems_initialize_before_drivers, rtems_initialize_device_drivers, and
	rtems_initialize_start_multitasking. This opened the sequence up so
	that bootcard() could provide a more robust and flexible framework
	which is easier to explain and understand. This also lays the
	groundwork for sharing the division of available memory between the
	RTEMS workspace and heap and the C library initialization across all
	BSPs.
