New description:

 This patch improves the method `Polynomial.squarefree_decomposition()` and
 adds a new method `Polynomial.any_root()`.  This has been split off from
 #8335, and is a dependency of that ticket.

Comment (by pbruin):

 New patch with various improvements.  Most importantly: improved
 documentation, removed unused parameter `extend` of `any_root`, which
 caused a doctest failure.
