[commit] prep work for cleanups.c

[dje at google dot com (Doug Evans)]

Hi.

I've committed this patch which does some preparatory work
before cleanups.c can be committed.

Regression tested on amd64-linux.

2012-04-17  Doug Evans  <dje@google.com>

	* utils.c (make_cleanup_freeargv): Use make_cleanup instead of
	make_my_cleanup.
	(make_cleanup_dyn_string_delete): Ditto.
	(make_cleanup_ui_file_delete): Ditto.
	(make_cleanup_ui_out_redirect_pop): Ditto.
	(make_cleanup_free_section_addr_info): Ditto.
	(make_cleanup_restore_integer): Ditto.
	(make_cleanup_unpush_target): Ditto.
	(make_cleanup_value_free_to_mark): Ditto.
	(make_cleanup_value_free): Ditto.
	(make_cleanup_free_so): Ditto.
