The page_number is now directly given to the StreetIndex constructor,
which in turn ensures that each IndexItem it creates have it.

The StreetIndex constructor was raising an exception when no street
was found. With the multi-page renderer, it is very possible to have
pages of map without any street or other elements to put in the index,
but for convenience we still want to get a StreetIndex object, even if
its ._categories list is empty.

The multi-page renderer needs to know on which page each IndexItem has
been found. Therefore, we introduce a new page_number field in the
IndexItem class. This field remains to None for the single page
renderers, and is used to store an integer by the multi-page renderer.

New maplib (map creation routines), indexlib (index creation routines)
and layoutlib (page layout & rendering) structure. Besides moving
files around, a new layoutlib.commons module has been create to host
the mm to/from pt conversion routines.
