d6c71dd061 Fix preprocessor indentation 
Indent the C preprocessor directives to reflect their nesting
using the following script:

$ cppi -l $(git grep -El '^[[:space:]]*#[[:space:]]*(if|ifdef|ifndef|elif|else|endif|define|pragma)[[:space:]]' |grep -v '\.sh$') |while read f; do
	cppi < "$f" > "$f".cppi; mv "$f".cppi "$f"
done

e3b80cb65f Introduce PTRACE_GET_SYSCALL_INFO support 
When PTRACE_GET_SYSCALL_INFO API works,
use it instead of traditional upeek/get_regs API.

Tested on x86_64 and x86.

* get_personality.c: New file.
* get_personality.h: Likewise.
* Makefile.am (strace_SOURCES): Add them.
* linux/aarch64/arch_get_personality.c: New file.
* linux/powerpc64/arch_get_personality.c: Likewise.
* linux/riscv/arch_get_personality.c: Likewise.
* linux/s390x/arch_get_personality.c: Likewise.
* linux/sparc64/arch_get_personality.c: Likewise.
* linux/tile/arch_get_personality.c: Likewise.
* linux/x32/arch_get_personality.c: Likewise.
* linux/x86_64/arch_get_personality.c: Likewise.
* linux/check_scno.c: Likewise.
* linux/x32/check_scno.c: Likewise.
* Makefile.am (EXTRA_DIST): Add them.
* linux/ia64/arch_getrval2.c (getrval2): Invoke get_regs()
if ptrace_syscall_info is in use.
* linux/mips/arch_getrval2.c: Likewise.
* linux/sparc/arch_getrval2.c: Likewise.
* defs.h (get_personality_from_syscall_info): New prototype.
* syscall.c: Include "get_personality.h" and "ptrace_syscall_info.h".
(get_regs_error): Define unconditionally.
(ptrace_sci): New static variable.
(clear_regs): Reset ptrace_sci.op.
(ptrace_syscall_info_is_valid, ptrace_get_syscall_info,
get_syscall_regs): New functions.
(get_syscall_result_regs): Change to get_syscall_regs.
(get_instruction_pointer, get_stack_pointer, get_scno, get_syscall_args,
get_error, set_error, set_success): Add ptrace_syscall_info support.
* tests/int_0x80.test: New test.
* tests/Makefile.am (DECODER_TESTS): Add int_0x80.test.
(XFAIL_TESTS_x86_64, XFAIL_TESTS_x32): Remove.
