(linux_kill): Stop all lwps here. Don't delete the main lwp here. (linux_detach_one_lwp): Assume the lwp is stopped. (any_thread_of): Delete. (linux_detach): Stop all lwps here. Don't blindly delete all breakpoints. (delete_lwp_callback): New. (linux_mourn): Delete all lwps of the process that is gone. (linux_wait_1): Don't delete the last lwp of the process here. * mem-break.h (mark_breakpoints_out): Declare. * mem-break.c (mark_breakpoints_out): New. (free_all_breakpoints): Use it. * server.c (handle_target_event): If the process is gone, mark breakpoints out. * thread-db.c (struct thread_db) <create_bp>: New field. (thread_db_enable_reporting): Fix prototype. Store a thread event breakpoint reference in the thread_db struct. (thread_db_load_search): Clear the thread_db object. (try_thread_db_load_1): Ditto. (switch_to_process): New. (disable_thread_event_reporting): Use it. (remove_thread_event_breakpoints): New. (thread_db_detach, thread_db_mourn): Use it.
