Make the stop_soon global be per-inferior instead.
* infcmd.c (attach_command_post_wait): Adjust. (attach_command): Likewise. * inferior.h (stop_soon): Delete. (struct inferior): Add stop_soon member. * infrun.c (stop_soon): Delete. (clear_proceed_status, start_remote) (fetch_inferior_event, handle_inferior_event): Adjust. (signal_stop_state): Don't check stop_soon here. Check in callers instead. (save_inferior_status, restore_inferior_status): Adjust. * linux-nat.c (linux_nat_resume, linux_nat_wait): Always pass signals to common code if starting up the inferior. * inferior.h (struct inferior_info): Added stop_soon member. * inferior.c (add_inferior) Clear stop_soon. * mips-tdep.c (heuristic_proc_start): Adjust. * nto-procfs.c (procfs_create_inferior): Adjust. * solib-irix.c (irix_solib_create_inferior_hook): Adjust. * solib-osf.c (osf_solib_create_inferior_hook): Adjust. * solib-sunos.c (sunos_solib_create_inferior_hook): Adjust. * solib-svr4.c (svr4_solib_create_inferior_hook): Adjust. * win32-nat.c (do_initial_win32_stuff): Adjust. * alpha-tdep.c (alpha_heuristic_proc_start): Adjust.
