another quick release

[Michal H. <ms...@gm...>]

Hi,
Jozo has found a serious regression in the 0.4.4.x release caused by
xpdf const clean up. This should be fixed now and maybe we should
push another quick release because this can have really nasty
consequences leading to obscure bugs.

We have also fixed a bug in XRef::entries initialization code which
resulted in a bad generation number used from free entries which leads
to a corrupted document in the end. This issue has been present in the
code from the early days. We were just lucky that we never hit it (it is
triggered only by documents which contain holes in the used objects
numbers and where a new object is created - apparently there are PDF
creators which produce such documents).

What do you guys think? I would go for 0.4.4.2.
