current_klongsize checks are more universal, therefore they are usually
shorter and easier to comprehend.
* desc.c (umove_kulong_array_or_printaddr): Check for current_klongsize
instead of current_personality and current_wordsize.
* io.c (print_lld_from_low_high_val): Likewise.
* lseek.c (SYS_FUNC(lseek)): Likewise.
* resource.c (decode_rlimit): Likewise.
* syscall.c (is_negated_errno): Likewise.
* util.c (getllval, getarg_klu): Likewise.
Fix multiple personalities support in parsers of getrusage, waitpid,
wait4, and waitid syscalls by converting printrusage into a mpersified
printer.
* defs.h (printrusage): Remove.
* printrusage.c (rusage_t): New typedef. Mpersify it.
(printrusage): Use it instead of struct rusage.
Wrap function name into MPERS_PRINTER_DECL.
* resource.c (sys_getrusage): Use mpersified printrusage.
* wait.c (printwaitn, sys_waitid): Likewise.
Introduce SYS_FUNC macro to declare and define all syscall parsers.
* Makefile.am (BUILT_SOURCES, CLEANFILES): Add sys_func.h.
(sys_func.h): New rule.
* defs.h (SYS_FUNC_NAME, SYS_FUNC): New macros.
* linux/syscall.h: Include "sys_func.h".
[NEED_UID16_PARSERS]: Use SYS_FUNC to declare uid16 syscall parsers.
Remove other declarations.
* linux/alpha/syscallent.h (160, 161): Add sys_ prefix to osf_statfs
and osf_fstatfs syscall parsers.
* *.c: Use SYS_FUNC to define syscall parsers.
When strace is built with large file support definitions in CFLAGS (as
may be provided by buildroot) the C library headers may expose a 64-bit
rlim_t even though the struct rlimit fields used by the system call
interface are only 32-bit. The SIZEOF_RLIM_T will then be 8 which
results in bad decoding of the getrlimit and setrlimit syscalls.
This is fixed by replacing unreliable SIZEOF_RLIM_T based checks with
checks for current_wordsize.

This is needed for simplified printf, and reduces code size a bit.
* block.c (block_ioctl): Cast the value to unsinged and use %u
instead of using %hu.
* desc.c (sys_io_cancel): Likewise.
* resource.c (sys_sysinfo): Likewise.

Conditions such as defined(LINUX) are always true now,
defined(FREEBSD) etc are always false.
When if directive has them as subexpressions, it can be simplified.
Another trivial changes here are fixes for directive indentation.
