Non-stop linux native.
* linux-nat.c (linux_test_for_tracefork): Block events while we're here. (get_pending_status): Implement non-stop mode. (linux_nat_detach): Stop threads before detaching. (linux_nat_resume): In non-stop mode, always resume only a single PTID. (linux_handle_extended_wait): On a clone event, in non-stop mode, add new lwp to GDB's thread table, and mark as running, executing and stopped appropriately. (linux_nat_filter_event): Don't assume there are other running threads when a thread exits. (linux_nat_wait): Mark the main thread as running and executing. In non-stop mode, don't stop all lwps. (linux_nat_kill): Stop lwps before killing them. (linux_nat_thread_alive): Use signal 0 to detect if a thread is alive. (send_sigint_callback): New. (linux_nat_stop): New. (linux_nat_add_target): Set to_stop to linux_nat_stop. * linux-nat.h (thread_db_attach_lwp): Declare. * linux-thread-db.c (thread_get_info_callback): Check for new threads if we have none. (thread_from_lwp, enable_thread_event): Set proc_handle.pid to the stopped lwp. Check for new threads if we have none. (thread_db_attach_lwp): New. (thread_db_init): Set proc_handle.pid to inferior_ptid. (check_event): Set proc_handle.pid to the stopped lwp. (thread_db_find_new_threads): Set proc_handle.pid to any stopped lwp available, bail out if there is none. * linux-fork.c (linux_fork_killall): Use SIGKILL instead of PTRACE_KILL.
