92e347b556 Add copyright headers to some files that lack them 
We do our best to keep copyright headers up to date, yet
git history provides better information on this subject
and is more accurate than copyright headers.

89636759d7 Automatically replace PRI_kr[dux] with PRI_kl[dux] 
Remove temporary macros created for transition from long
to kernel_ulong_t.

Automatically replace PRI_kr[dux] with PRI_kl[dux] using
$ git grep -l 'PRI_kr[dux]' | xargs sed -ri 's/PRI_kr([dux])/PRI_kl\1/g'

* defs.h (PRI_krd, PRI_kru, PRI_krx): Remove.  All users updated.

1d5bb61c49 Print kernel_ureg_t and kernel_scno_t using dedicated format strings 
Prepare for the change of kernel_ureg_t and kernel_scno_t from
unsigned long to kernel_ulong_t.

* defs.h (PRI_krd, PRI_kru, PRI_krx): New temporary macros.
All users updated.

9af28a4d13 Fix decoding of sethostname syscall 
The second argument of sethostname syscall is not an unsigned long but
unsigned int.  The kernel does not look at the string argument when
the length argument is too long.

* hostname.c [HAVE_LINUX_UTSNAME_H]: Include <linux/utsname.h>.
[!__NEW_UTS_LEN] (__NEW_UTS_LEN): Define.
(SYS_FUNC(sethostname)): Treat the second argument as unsigned int.
Print the first argument as a pointer when the second argument exceeds
__NEW_UTS_LEN.
* tests/sethostname.c [HAVE_LINUX_UTSNAME_H]: Include <linux/utsname.h>.
[!__NEW_UTS_LEN] (__NEW_UTS_LEN): Define.
(main): Use it.  Check that the second argument of sethostname
is handled as unsigned int.  Check that the first argument is printed
as a pointer when the second argument exceeds __NEW_UTS_LEN.

a940d1a60f printstr: rename to printstrn, add printstr as a thin wrapper 
As about half of all printstr uses cases are invocations with the last
argument set to -1, create a dedicated function for this use case.

* defs.h (printstr): Rename to printstrn.  All callers updated.
(printstr): New static inline function.  All callers updated.

a0bd3749fc Declare syscall parsers using SYS_FUNC macro 
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.

03c06ea592 process.c: move sethostname and gethostname parsers to a separate file 
* hostname.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* process.c (sys_sethostname, sys_gethostname): Move to hostname.c.
