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.

5a6dff3fe8 Include <sys/ptrace.h> early
Include "ptrace.h" before any header that can include <signal.h>
because on some architectures the latter may include <asm/sigcontext.h>
which in turn may include <asm/ptrace.h> with potentially devastating
effect on <sys/ptrace.h>.

* process.c: Include "ptrace.h" before "regs.h".
* rt_sigframe.c: Likewise.
* sigreturn.c: Include "ptrace.h" before "nsig.h".
* syscall.c: Likewise.
* wait.c: Include "ptrace.h" before <sys/wait.h>.
* strace.c: Include "ptrace.h" before <signal.h>.
* tests/ptrace.c: Likewise.
* tests/test_ucopy.c: Include <sys/ptrace.h> before <signal.h>.

5a25466437 Move NSIG ifdefery to a separate header file
* nsig.h: New file.
* Makefile.am (strace_SOURCES): Add it.
* signal.c: Include "nsig.h" instead of <signal.h>, remove
NSIG workarounds.
* sigreturn.c: Likewise.
* syscall.c: Likewise.
* tests/pselect6.c: Likewise.

527b42ff8d cleanup: make arch_sigreturn.c files more readable
Make arch_sigreturn.c files more self-sustained.  While they are
still being included by sigreturn.c, the latter no longer defines
arch_sigreturn function.

* linux/alpha/arch_sigreturn.c (arch_sigreturn): Define.
* linux/arm/arch_sigreturn.c: Likewise.
* linux/crisv10/arch_sigreturn.c: Likewise.
* linux/i386/arch_sigreturn.c: Likewise.
* linux/ia64/arch_sigreturn.c: Likewise.
* linux/m68k/arch_sigreturn.c: Likewise.
* linux/microblaze/arch_sigreturn.c: Likewise.
* linux/mips/arch_sigreturn.c: Likewise.
* linux/powerpc/arch_sigreturn.c: Likewise.
* linux/s390/arch_sigreturn.c: Likewise.
* linux/sparc/arch_sigreturn.c: Likewise.
* linux/tile/arch_sigreturn.c: Likewise.
* linux/x32/arch_sigreturn.c: Remove code.
Include "x86_64/arch_sigreturn.c".
* linux/x86_64/arch_sigreturn.c: Stop including "x32/arch_sigreturn.c".
Include "i386/arch_sigreturn.c" with arch_sigreturn temporarily defined
to i386_arch_sigreturn.
(arch_sigreturn): Define.  Add x32 personality support there.
* sigreturn.c: Remove arch_sigreturn header and footer.
