sysdecode_ioctlname() function. This function matches the behavior of the truss variant in that it returns a pointer to a string description for known ioctls. The caller is responsible for displaying unknown ioctl requests. For kdump this meant moving the logic to handle unknown ioctl requests out of the generated function and into an ioctlname() function in kdump.c instead.
