* defs.h: Add new struct tcb fields: wait_status, next_need_service.
make flags field wider (ints are easier to work with on many CPUs).
* strace.c (trace): Split this function into two:
collect_stopped_tcbs() and handle_stopped_tcbs().
Now we collect *all* waitable tasks, then handle them all,
then repeat.
Fixes RH#478419 "Some threads stop when strace with -f option
is executed on a multi-thread process"
* test/many_looping_threads.c: example program which cna't be straced
successfully without this fix.
