remove ambiguous incompatibility between coeffs() and coefficients()

[johnperry-math]

This ticket adds a sparse parameter to the coefficients() method of the Polynomial class, and deprecates the use of coeffs() in a manner inconsistent with coefficients(), keeping with the discussion at https://groups.google.com/forum/#!topic/sage-devel/IHirUHTWnuA. See also trac #17438.

preliminary patch; main work done but a lot of doctests to go

I'm still working on this; I wanted to push my commits for the time being. I'm pretty sure it only needs additional doctests, but if anyone wants to go ahead & look at the documentation & doctests of polynomial_element.pyx and polynomial_element_generic.py, it would be convenient for me to fix any problems with them tonight or tomorrow. :-)

PS: Sorry about removing the CC: earlier. It's nothing personal; I'm just clumsy.

I've found all the doctests in need of modification that I can find, so, I think this is ready for review.

Looks fine, doesn't clash with #17438, and passes make ptestlong. Please adapt the Author: field.
