Joe Hershberger fd3056337e net: Use env callbacks for net variables ...

Instead of checking for changes to the env each time we enter the
net_loop, use the env callbacks to update the values of the variables.
Don't update the variables when the source was programmatic, since the
variables were the source of the new value.
