md/bitmap has some attributes per-page. Handling of these attributes in
largely abstracted in set_page_attr and clear_page_attr. However
get_page_attr exposes the format used to store them. So prior to changing
that format, introduce test_page_attr instead of get_page_attr, and make
appropriate usage changes.
