Here is the latest I have put together.  It has both the wrap and the 
public val property.

Simple test case
-----------------

from myhdl import *
x = intbv(0, min=-8, max=8, wrap=True)
x[:] = x + 1
assert x == 1
x[:] = x + 2
assert x == 3
x[:] = x + 5
assert x == -8
x[:] = x + 1
assert x == -7
x[:] = x - 5
assert x == 4
x[:] = x - 4
assert x == 0
x[:] = x - 1
assert x == -1
