ui: factor out ui.load() to create a ui without loading configs (API)

This allows us to write doctests depending on a ui object, but not on global
configs.

ui.load() is a class method so we can do wsgiui.load(). All ui() calls but
for doctests are replaced with ui.load(). Some of them could be changed to
not load configs later.
