Title: Fix pack() and unpack() bugs.

pack() and unpack() have bugs due to stepping through both arrays
8-at-a-time: the compressed version of the bool array isn't actually
very compressed - 16 bools packed into 9 bytes.

This isn't noticed because testPackUnpackC() doesn't call pack() and
unpack() with the correct N argument, instead understanding the size
of the arrays by eightfold.
