* 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.
