* score/include/rtems/score/object.h,
score/src/objectallocatebyindex.c: Object index should be int.
Fix bug when index is negative.
* score/src/objectextendinformation.c: Do not allow maximum number
of allocated objects to exceed maximum representable in index
field of Object Id.
* score/src/objectgetisr.c: Use same code that is in _Objects_Get
to extract index field of Object Id.
