PR 1924/cpukit
* sapi/include/rtems/config.h: Added stack_allocate_init_hook to
rtems_configuration_table.
* sapi/include/confdefs.h: Added CONFIGURE_TASK_STACK_FROM_ALLOCATOR
and CONFIGURE_TASK_STACK_ALLOCATOR_INIT defines. Set default stack
allocator and free hook to _Workspace_Allocate() and _Workspace_Free()
respectively.
* score/src/thread.c, score/src/threadstackallocate.c,
score/src/threadstackfree.c: Update due to API changes.
