Comment:
The attached patch adds a radical() function, functions
Factorization.radical() and Factorization.radical_value(). It also fixes
a bug in the radical of a polynomial where the content was not accounted
for.
It also changes the output of radical(), in a way which I think makes more
sense: radical(0) now gives an error instead of returning 1 and the
radical of a negative number is positive (instead of negative).
In order for all doctests to succeed, you need to apply also the patches
for #9450.
