Split up loadset and storeset, moving vpage read/write stuff into load_from_page and store_to_page.

Get rid of bpage and almost everywhere that wrkpage was used.

These split out functions don't use setpicstuf. It turns out that finally nothing
actually depends on setpicstuf setting wrkpage or bpage anymore.
