Previously the private feature flags were stored in an enum and we already had 31 flags. Adding the 32nd flag would presumably make it add -2³¹ as one of the values which might cause problems. To avoid this we'll just use an fixed-size array of longs and use indices for the enum values like we do for the public features. A slight complication with this is in the CoglDriverDescription where we were previously using a static intialised value to describe the set of features that the driver supports. We can't easily do this with the flags array so instead the features are stored in a fixed-size array of indices.
