* inf-ttrace.c (inf_ttrace_him): Set TTEVT_BPT_SSTEP if available.
(inf_ttrace_attach): Likewise.
(inf_ttrace_resume_callback): New function.
(inf_ttrace_resume): Don't use TT_PROC_CONTINUE. Iterate over all
lwps and call inf_ttrace_resume_callback instead.
(inf_ttrace_wait): Handle TTEVT_BPT_SSTEP.
