[PATCH 2/5] constify to_terminal_info

[Tom Tromey <tromey at redhat dot com>]

This constifies the to_terminal_info method.

I could not test all of it (e.g., go32-nat.c) but I did look by hand
and it all seems fine.  I'd appreciate it if someone with access to
the proper machines either built this or looked at it.

	* go32-nat.c (go32_terminal_info): Make 'args' const.
	* inferior.h (child_terminal_info): Update.
	* inflow.c (child_terminal_info): Make 'args' const.
	* target.c (default_terminal_info): Make 'args' const.
	(debug_to_terminal_save_ours): Likewise.
	* target.h (struct target_ops) <to_terminal_info>: Make argument
	const.
