enforce options definitions to bind the enum and the descriptor
This uses some macro trickery to make sure that there's one-to-one
mapping with the option index enum and the descriptor. The down
side is that enum's are generated via #define's and editors might
not pick them up for auto completion, but the benefits are more:
it's no longer possible have mismatching enum value and descriptor
index, and the amount of source code lines is less.
