c40270dd87 i386, x32: use upoke() instead of set_regs() 
This brings i386 and x32 in line with x86_64
and removes redundant HAVE_GETREGS_OLD checks.
Besides that, use of PTRACE_GET_SYSCALL_INFO would require
an extra get_regs() invocation before set_regs().

* syscall.c (ARCH_MIGHT_USE_SET_REGS): Define to 1.
[HAVE_GETREGS_OLD] (ARCH_MIGHT_USE_SET_REGS): Redefine to 0.
(ptrace_setregset_or_setregs): Check ARCH_MIGHT_USE_SET_REGS instead
of HAVE_GETREGS_OLD.

5be511bf86 upoke: workaround crippled x32 
As PTRACE_POKEUSER is crippled on x32 by design from the very first
linux kernel commit v3.4-rc1~33^2~2 when it was introduced,
workaround this by using the raw x86_64 syscall instead.

* linux/ptrace_pokeuser.c: New file.
* linux/x32/ptrace_pokeuser.c: Likewise.
* Makefile.am (EXTRA_DIST): Add them.
* upoke.c: Include "ptrace_pokeuser.c".
(upoke): Use ptrace_pokeuser instead of ptrace.

of get_syscall_args() to arch_get_syscall_args().

eca7e95886 Move kill_save_errno to a separate header file 
This function is going to be used outside strace.c,
so make it globally available and move it to a separate header file.

* strace.c (kill_save_errno): Add "inline" keyword, change return type
from "void" to "int", move the function ...
* kill_save_errno.h: ... to this new file.
* Makefile.am (strace_SOURCES): Add it.

422ecbe675 syscall_entering_trace: set TCB_FILTERED along with TCB_HIDE_LOG 
This allows to remove some of hide_log() checks that became redundant.

* syscall.c (syscall_entering_trace): Set TCB_FILTERED along with
TCB_HIDE_LOG, remove now redundant hide_log(tcp) check.
(syscall_exiting_decode): Replace "filtered(tcp) || hide_log(tcp)"
with "filtered(tcp)".

7a4c6b715d syscall_entering_trace: optimize clearing of TCB_HIDE_LOG flag 
* syscall.c (syscall_entering_trace): Since we check for TCB_HIDE_LOG
flag anyway, do not clean it unless it is set.

62267a93f4 print_inet_addr: print nameless and named addresses using the same style 
* sockaddr.c (print_inet_addr): Handle var_name == NULL case in a more
structured way: use inet_addr("%s") form to print AF_INET addresses
in structureless contexts where no structure field name is available.
Likewise, use inet_pton(AF_INET6, "%s") that case.
* tests/nlattr_ifaddrmsg.c (main): Update expected output.
* tests/nlattr_ifla_af_spec.c (main): Likewise.

Complements: v4.19~76 "print_inet_addr: add support of invocations without field name"
