Clean up a the driver's DDC code, make it simpler, more robust, and mostly self contained. The patches in this patchset have previously been sent as part of rev 1 of [1]. Patches 1 and 2 fix long-standing problems in the DDC code. Patches 3 to 9 refactor the DDC code. The code then keeps its data structures internal, acquires locks automatically and is much more readable overall. Patch 10 replaces driver code with an equivalent helper. Tested on various Matrox hardware.
