Patch by Kirill A. Shutemov:
Fix some warnings on ARM build.
* defs.h: include <sys/ptrace.h> on arm too.
* syscall.c: EABI arm does not need decode_subcall(), ifdef it out.

* defs.h: Remove sigtrap80 field from struct tcb.
* strace.c: Add ptrace_stop_sig static variable
and use it in place of tcp->sigtrap80.
Add ptrace_opts_set static flag variable.
(trace): Set ptrace options once, not per-process.
If unexpected SIGTRAP is later received,
revert back to using SIGTRAP
(assume old, broken kernel).

Make strace correctly handle SIGTRAP produced by e.g.
kill(2) and by trapping instruction.
* defs.h: Add sigtrap80 field to struct tcb.
* strace.c (alloc_tcb): Initialize it to SIGTRAP.
(detach): Use tcp->sigtrap80 instead of SIGTRAP constant.
(trace): Attempt to set PTRACE_O_TRACESYSGOOD and
PTRACE_O_TRACEEXEC options on each newly attached process,
distinquish between SIGTRAP and (SIGTRAP | 0x80) stops.
Fixes RH#162774 "strace ignores int3 SIGTRAP".
