Eugene Syromyatnikov 3b4612b3ac Print indirect pointers as pointers
Originally, printnum_long_int was used, but it prints NULL incorrectly.

* defs.h (DECL_PRINTNUM_ADDR): New macro.
(DECL_PRINTNUM_ADDR(int), DECL_PRINTNUM_ADDR(int64)): New prototypes.
[!current_wordsize] (printnum_addr_long_int): New prototype.
[!current_wordsize] (printnum_ptr): Use it.
[current_wordsize > 4] (printnum_ptr): Use printnum_addr_int64.
[current_wordsize == 4] (printnum_ptr) Use printnum_addr_int.
* util.c (DEF_PRINTNUM_ADDR): New macro.
(DEF_PRINTNUM_ADDR(int, unsigned int),
DEF_PRINTNUM_ADDR(int64, uint64_t)): New macro instantiations that
provide printnum_addr_int and printnum_addr_int64, accordingly.
[!current_wordsize] (printnum_addr_long_int): New function.
* xet_robust_list.c (sprintaddr): New function.
(main): Use it, update expected output.
* tests/ipc_sem.c (main): Update expected output.
