Use poppler instead of including xpdf source code. Poppler is a
fork of xpdf to build it as a shared library. See
http://freedesktop.org/wiki/Software/poppler.
* pdf/xpdf/*, pdf/goo/*, pdf/splash/*, pdf/fofi/*: Remove included
xpdf fork.
* pdf/Makefile.am: Build libpdfdocument.a here.
* pdf/GDKSplashOutputDev.cc:
* pdf/GDKSplashOutputDev.h:
* pdf/GnomeVFSStream.cc:
* pdf/GnomeVFSStream.h:
* pdf-document.cc:
* pdf-document.h:
* test-gdk-output-dev.cc
* Thumb.cc:
* Thumb.h: Pull these files out of pdf/xpdf and adjust to compile
against poppler.
