Fix a bug which caused panics when attempting to change just the flags of
a route. (This still doesn't work, but it doesn't panic now.) It looks
like there may be a number of incipient bugs in this code.
Also, get ready for the time when all IP gateway routes are cloning, which
is necessary to keep proper TCP statistics.
