A temp fix for bugs 692038 and 692065. The clist devices that are created for the threads now inherit the icc profile from the target device. I need to set things up so that the device profile is no longer reference counted since we could have a race condition problem if the different threads are incrementing and decrementing the count and if the command is not atomic on a particular architecture. The plan will be to no longer ref count the device profile but to have it maintained until the the actual target device is destroyed. There will be a bit of work to do with respect to the pdf14 device, which can have a device profile that is different than the actual target device. That profile can be altered with the transparency group pushes and pops.
