Fix leak during text extraction.
MuPDF (the win32/linux viewer) leaks a span_soup each time it
is run, even if (seemingly to the user) no text extraction
operations are done.
This is because the view does a text extraction pass silently,
during which 'begin_page' is called for both page contents and
annotation contents. This causes a leak of a span_soup.
Change the implementation to allocate the span_soup just in time
instead.
