Log:
[utils] Fix incompatibility of bisect[-skip-count] with Python 3

Summary:
This change replaces the print statements with print function calls
and also replaces the '/' operator (which is integer division in Py2,
but becomes floating point division in Py3) with the '//' operator
which has the same semantics in Py2 and Py3.
