Create a new memory display format for an address that comes from
a slab object, consisting of the slab cache name and the address
value, separated by a colon, and encompassed in brackets:

  [slab-cache-name:address]

Enhanced the "bt -F" option such that if "-F" is entered twice,
and if the stack frame contents reference a slab cache object, both
the slab cache name and the stack contents will be displayed within
brackets.

Enhanced the "rd -S" option such that if "-S" is entered twice,
and if the memory contents reference a slab cache object, both the
slab cache name and the memory contents will be displayed within
brackets.
