* objfiles.h: Delete comments refering to inside_entry_func and

	DEPRECATED_FRAME_CHAIN_VALID.
	* defs.h (inside_entry_func): Update prototype..
	* blockframe.c (inside_entry_func): Rename to
	legacy_inside_entry_func.  Add new inside_entry_func taking a frame.
	* frame.c (get_prev_frame): Pass the frame to inside_entry_func.
