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".
