Add a new function to print a thread ID, in the style of paddress, plongest, etc. and adjust all CLI-reachable paths to use it. This gives us a single place to tweak to print inferior-qualified thread IDs later: - [Switching to thread 1 (Thread 0x7ffff7fc2740 (LWP 8155))] + [Switching to thread 1.1 (Thread 0x7ffff7fc2740 (LWP 8155))] etc., though for now, this has no user-visible change. No regressions on x86_64 Fedora 20. gdb/ChangeLog: 2016-01-13 Pedro Alves <palves@redhat.com> * breakpoint.c (remove_threaded_breakpoints) (print_one_breakpoint_location): Use print_thread_id. * btrace.c (btrace_enable, btrace_disable, btrace_teardown) (btrace_fetch, btrace_clear): Use print_thread_id. * common/print-utils.c (CELLSIZE): Delete. (get_cell): Rename to ... (get_print_cell): ... this and made extern. Adjust call callers. Adjust to use PRINT_CELL_SIZE. * common/print-utils.h (get_print_cell): Declare. (PRINT_CELL_SIZE): New. * gdbthread.h (print_thread_id): Declare. * infcmd.c (signal_command): Use print_thread_id. * inferior.c (print_inferior): Use print_thread_id. * infrun.c (handle_signal_stop) (insert_exception_resume_breakpoint) (insert_exception_resume_from_probe) (print_signal_received_reason): Use print_thread_id. * record-btrace.c (record_btrace_info) (record_btrace_resume_thread, record_btrace_cancel_resume) (record_btrace_step_thread, record_btrace_wait): Use print_thread_id. * thread.c (thread_apply_all_command): Use print_thread_id. (print_thread_id): New function. (thread_apply_command): Use print_thread_id. (thread_command, thread_find_command, do_captured_thread_select): Use print_thread_id.
