2479ef0bce Fix printing tracee's long integers 
Replace ambiguous printnum_long that used to fetch native long integers
from tracee's memory with printnum_ptr, printnum_slong, and printnum_ulong
that fetch tracee's pointer, signed long, and unsigned long integers.

* defs.h (printnum_long, printpair_long): Remove prototypes.
(printnum_int64, printpair_int64): Remove macros, declare functions
unconditionally.
[SUPPORTED_PERSONALITIES > 1 && SIZEOF_LONG > 4] (printnum_long_int):
New prototype.
(printnum_ptr, printnum_slong, printnum_ulong): New macros.
* aio.c (sys_io_setup): Use printnum_ulong.
* block.c (block_ioctl): Use printnum_slong and printnum_ulong.
* get_robust_list.c (sys_get_robust_list): Use printnum_ptr
and printnum_ulong.
* io.c (print_off_t): Remove.
(sys_sendfile): Use printnum_ulong.
* ipc.c (sys_semctl): Use printnum_ptr.
* prctl.c (sys_prctl): Likewise.
* process.c (sys_ptrace): Likewise.
* rtc.c (rtc_ioctl): Use printnum_ulong.
* util.c (printnum_long, printpair_long): Remove.
(printnum_int64, printpair_int64): Define unconditionally.
[SUPPORTED_PERSONALITIES > 1 && SIZEOF_LONG > 4] (printnum_long_int):
New function.

3691562e7d prctl: fix decoding of unrecognized commands 
The use of printargs introduced by commit v4.10-179-g210a6b6 is wrong:
when the first argument is already printed, printargs cannot be called.

* prctl.c (print_prctl_args): New function.
(sys_prctl): Use it.

850ba4b1e9 Change printnum_* printers to honor syserror 
With this change, printnum_* printers will not attempt to fetch data
in case of exiting(tcp) && syserror(tcp).
All "at exiting" decoders that call these printers have been made
ready for this change in previous commits.

* util.c (DEF_PRINTNUM, DEF_PRINTPAIR): Use umove_or_printaddr.
* prctl.c (prctl_exit): Use printnum_int and printnum_long.
(sys_arch_prctl): Do not check for syserror.

(sys_func.h): New rule.
* defs.h (SYS_FUNC_NAME, SYS_FUNC): New macros.

8224758b33 Always compile sys_prctl parser 
Since sys_prctl is referenced by syscallent files unconditionally,
conditional compilation of sys_prctl depending on prctl availability is
pointless.

* prctl.c (unalignctl_string, sys_prctl): Compile unconditionally.
