* inflow.h (our_process_group): Remove declaration. (inferior_process_group): Delete global variable declaration. (inferior_process_group): New function declaration. * inflow.c: Include observer.h.

(inferior_thisrun_terminal): Extend description comment. (gdb_has_a_terminal): Adjust to write to our_terminal_info fields instead of globals. (terminal_init_inferior_with_pgrp): Adjust to per-inferior terminal settings. (terminal_inferior): Ditto. (terminal_ours_1): Ditto. (inflow_new_inferior, inflow_inferior_exit): New functions. (child_terminal_info): Adjust to per-inferior terminal settings. (osig_set): New global. (set_sigint_trap): Adjust to per-inferior terminal settings. Set or clear `osig_set' accordingly. (clear_sigint_trap): Check `osig_set' to decide wheater to restore SIGINT handler, instead of checking the current inferior (which may be none). (_initialize_inflow): Attach inflow_new_inferior and inflow_inferior_exit to the "new_inferior" and "inferior_exit" notifications, respectively. * inferior.h (struct terminal_info): Forward declare. (struct inferior): Add `terminal_info' field. * inferior.c (delete_inferior_1): Notify the inferior_exit observers before removing the inferior from the lists and deleting it. * inf-ptrace.c (inf_ptrace_stop): `inferior_process_group' is now a function instead of a variable. Adjust. * procfs.c (procfs_stop): Ditto.
