arbitrary range of bits embedded in the middle of another bignum.
This kind of operation is desirable in many cases of software
floating point, e.g. converting bignum integers to floating point
numbers of fixed precision (you want to extract the precision most
significant bits).

Elsewhere, add an assertion, and exit the shift functions early if
the shift count is zero.

convertFromZeroExtendedInteger can be simplified as it doesn't need
to make a copy of the source bignum.

This interface is saner and the implementation more efficient.  It will
be needed for decimal->binary conversion.

modified the function to expect zero-extended input.  Make this
