make bernoulli_polynomial independent of maxima
Comment:
The attached patch rewrites `bernoulli_polynomial` to avoid Maxima
completely. This gives roughly a factor of 10 speedup.
Unfortunately, the originial request doesn't quite make sense --
`bernoulli_polynomial(x,n)` for `n` a symbolic variable would have to
return a polynomial of variable degree. As it stands, we don't have any
sort of "symbolic sum" to use for that kind of thing. I did add the
formula for the `n`th Bernoulli polynomial to the docstring, though.
