debian/patches/cups-raster-error-out-without-segfault-and-force-banding.dpatch,
debian/patches/cups-raster-fix-memory-reallocation.dpatch: Fixed several
problems in the PDF interpreter and the CUPS Raster output device of
Ghostscript to avoid Ghostscript erroring out or even crashing on many
input files when printing with a CUPS Raster driver (LP: 539708, upstream
bug #691014). Joined all changes on cups/gdevcups.c into one patch as
the patches are overlapping and parts of the old patches are undone.
