On Apery numbers and generalized central trinomial coefficients

We decide to combine this preprint with two other ones (arXiv:1101.1946 and arXiv:1008.3887). The results on Apery numbers and polynomials will be added to the new version of arxiv:1101.1946, and those results on generalized trinomial coefficients will be added to the new version of arxiv:1008.3887
