ruby: DataBlock method changes w/ manual subsequent initializations

The data block initialization depended on the statically declared block size
for its internal bitmask.  We change the default behavior to initialize an
empty bitmask in cases where the block size cannot be passed via a parameter
list; subsequently we immediately initialize the data block with the size
for objects that need the data block.
