PR 1924/cpukit
* sapi/include/rtems/config.h: New fields stack_space_size,
unified_work_area, and stack_allocator_avoids_work_space in
rtems_configuration_table.
* sapi/include/confdefs.h: Removed rtems_unified_work_area (this is
now part of the Configuration). Separate work space and stack space
estimate. Added CONFIGURE_TASK_STACK_ALLOCATOR_AVOIDS_WORK_SPACE
configuration option.
* libmisc/shell/main_wkspaceinfo.c, score/src/wkspace.c,
libcsupport/src/malloc_initialize.c: Update due to API changes.
