Subject: [PATCH] Guard against NULL 'base' for non-clist devices
Bug #696246 "Ghostscript 9.18 with -dFirstPage/-dLastPage fails for ijs and some x11 devices"
This is actually for the plib device. This device is currently (this will
change in the next commit) set to BandingAuto, despite the fact that the
device only works in banding mode.
This can lead to use arriving in gdev_mem_open_scan_lines with all of
mdev->bitmap_memory, mdev->line_pointers_memory and mdev->base being set to
NULL. The code didn't check and assumed that mdev->base was valid, which
led to a later seg fault.
Here we just check to make sure it isn't NULL and return an error if it is.
This doesn't prevent the possibility of garbage uninitialised values, but
there's not much we can do to check that at this stage, devices are supposed
to be initialised to 0 so this 'shouldn't' happen.
No differences expected.

Subject: [PATCH] Ensure plib devices always use the clist
Bug #696246 "Ghostscript 9.18 with -dFirstPage/-dLastPage fails for ijs and some x11 devices"
the plib* class of devices only work if clist is present, but previously
they left the banding_type set to 'auto', which meant that under some
conditions we did not use the clist, leading to a seg fault.
This commit simply forces banding_type to be 'BandingAlways'.
No differences expected.

Subject: [PATCH] prevent rinkj device crash when misconfigured (no SetupFile)
Bug #696246 "Ghostscript 9.18 with -dFirstPage/-dLastPage fails for ijs and some x11 devices"
The rinkj device requires a SetupFile to be given as a device parameter,
however it doesn't actually check to see if one is given, and just tries
to open the filename, with a predictable crash when none is given.
Here we check the filename and attempt to ensure it is both present and
minimally valid.
No differences expected.
