Do not return to BSP context in the exit() shutdown path. This makes it
possible to re-use the initialization stack. It can be used for the
interrupt stack for example. On targets with a small RAM this is a
considerable benefit.
This change eliminates also some special cases and simplifies the code.
Use an ISR lock to protect the system state change in
rtems_shutdown_executive().
Delete _Thread_Set_global_exit_status(),
_Thread_Get_global_exit_status() and _Thread_Stop_multitasking().
v2: Use ISR lock instead of _Thread_Disable_dispatch() to avoid lock down of
other processors. Format changes.
There is more work to do here. The shutdown sequence in the SMP configuration
is still broken. I will work on this the next days.
