GDB has a function named "current_inferior" and gdbserver has a global variable named "current_inferior", but the two are not equivalent; indeed, gdbserver does not have any real equivalent of what GDB calls an inferior. What gdbserver's "current_inferior" is actually pointing to is a structure describing the current thread. This commit renames current_inferior as current_thread in gdbserver to clarify this. It also renames the function "set_desired_inferior" to "set_desired_thread" and renames various local variables from foo_inferior to foo_thread. gdb/gdbserver/ChangeLog: * inferiors.h (current_inferior): Renamed as... (current_thread): New variable. All uses updated. * linux-low.c (get_pc): Renamed saved_inferior as saved_thread. (maybe_move_out_of_jump_pad): Likewise. (cancel_breakpoint): Likewise. (linux_low_filter_event): Likewise. (wait_for_sigstop): Likewise. (linux_resume_one_lwp): Likewise. (need_step_over_p): Likewise. (start_step_over): Likewise. (linux_stabilize_threads): Renamed save_inferior as saved_thread. * linux-x86-low.c (x86_linux_update_xmltarget): Likewise. * proc-service.c (ps_lgetregs): Renamed reg_inferior as reg_thread and save_inferior as saved_thread. * regcache.c (get_thread_regcache): Renamed saved_inferior as saved_thread. (regcache_invalidate_thread): Likewise. * remote-utils.c (prepare_resume_reply): Likewise. * thread-db.c (thread_db_get_tls_address): Likewise. (disable_thread_event_reporting): Likewise. (remove_thread_event_breakpoints): Likewise. * tracepoint.c (gdb_agent_about_to_close): Renamed save_inferior as saved_thread. * target.h (set_desired_inferior): Renamed as... (set_desired_thread): New declaration. All uses updated. * server.c (myresume): Updated comment to reference thread instead of inferior. (handle_serial_event): Likewise. (handle_target_event): Likewise.
