* net.c (print_group_req): Likewise.
* sock.c (PRINT_IFREQ_ADDR): Remove.
(print_ifreq, print_ifconf_ifreq): Use PRINT_FIELD_SOCKADDR

print_sockaddr does not use its first argument, remove it.
* defs.h (print_sockaddr): Remove argument.

Include <linux/ioctl.h> for <linux/sockios.h> on alpha, sh, and sh64
architectures because their <asm/sockios.h> use _IOR and _IOW macros
but don't include anything that would define these macros.
Being a wrapper around <linux/ioctl.h>, <sys/ioctl.h> brings
no benefits in this case. <ioctls.h> simply doesn't exist.
* sock.c [ALPHA || SH || SH64]: Include <linux/ioctl.h>
instead of <sys/ioctl.h> or <ioctls.h>.
* pathtrace.c (pathtrace_match): Change all comparisons with function
pointers to a single SEN based switch.

with function pointers to comparisons with SENs.

functions.
(sock_ioctl) Use them. Use umove_or_printaddr.
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.

[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.
The decoding of SIOCSIFNAME is incorrect. It does not use
the ifr_index field to look things up, but ifr_newname.
* sock.c (sock_ioctl): Split out SIOCSIFNAME from SIOCGIFNAME and
display ifr_newname.
The ifr name fields of the ifreq structure might not be NUL terminated.
If the user makes an ioctl call where they aren't, then strace ends up
reading random content from its own stack. Limit the printf lengths.
