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.

* linux/x86_64/set_error.c [!HAVE_GETREGS_OLD]: Remove.
* linux/x86_64/set_scno.c: Likewise.

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.

Refactor get_syscall_args() and get_error()

of get_error() to arch_get_error().
* linux/*/get_syscall_args.c: Rename all arch-specific implementations
of get_syscall_args() to arch_get_syscall_args().
* syscall.c (get_syscall_args, get_error): New functions.
(tamper_with_syscall_exiting, get_syscall_result): Do not clear
tcp->u_error before get_error() invocation as the latter does it now.

Refactor stack pointers

Change all linux/*/arch_regs.c to provide either ARCH_SP_REG
or ARCH_SP_PEEK_ADDR.  Introduce get_stack_pointer(), rewrite
all code accessing stack pointers to use get_stack_pointer().
On some architectures stack pointers were referred to as frame pointers,
clean up this confusion.

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.

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)".

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.

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"

tests: extend test coverage of RND* ioctl commands

* tests/ioctl_random.c (main): Check the error path of RNDADDENTROPY
parser.  Check decoding of unrecognized RND* ioctl commands.

Add support for /dev/[u]random ioctls

* random_ioctl.c: New file.
* Makefile.am (strace_SOURCES): Add it.
* defs.h (DECL_IOCTL): Add random.
* ioctl.c (ioctl_decode): Add 'R' case.
* xlat/random_ioctl_cmds.in: New file.
* tests/ioctl_random.c: New file.
* tests/.gitignore: Add ioctl_random.
* tests/pure_executables.list: Likewise.
* tests/gen_tests.in (ioctl_random): New entry.

tests: fix build with recent kernel headers

Linux commit v4.19-rc2-5-g2ecefa0a15fd0ef88b9cd5d15ceb813008136431

way again.  Workaround this issue by using designated initializers.

* tests/keyctl.c (main): Use designated initializers for
struct keyctl_dh_params.
