Added dot product tests from different frames.
Minor Fix.
Added print statements and modified assertion tests
Added correct print statements
Assertion tests satisfying new trigsimp changes
series method doesn't correctly work for n=0
deleted removeO method in tests
faster ``gf_edf_zassenhaus`` using the Frobenius map
renamed ``gf_monomials_mod`` and ``_gf_pow_p_mod``;
fixed a bug; added doctests and a test.
optimized ``gf_frobenius_monomial_base``; added ``_gf_trace_map``
fixed bug in ``gf_frobenius_monomial_base``; ``faster gf_irred_p_rabin``
Added keyword parameter ``expect`` to ``gf_irreducible_p``
and ``gf_irred_p_rabin``

If it is expected that the polynomial is irreducible, the ``expect=True``
option is faster, e.g.

In [1]: from sympy.polys.galoistools import gf_irreducible_p

In [2]: f = ZZ.map([1, 0, 2, 1, 0, 2, 1, 0, 2, 0, 2, 1, 0, 1, 1, 1, 2, 1, 1,
   ...: 1, 1, 0, 2, 1, 0, 2, 2, 2, 1, 2, 0, 2, 1, 1, 2, 1, 1, 0, 2, 2, 0, 2,
   ...: 1, 0, 2, 2, 0, 2, 2, 1, 1])

In [3]: timeit gf_irreducible_p(f, 3, ZZ, True)
10 loops, best of 3: 29.2 ms per loop

In [4]: timeit gf_irreducible_p(f, 3, ZZ)
1 loops, best of 3: 255 ms per loop
fixed a bug in ``gf_frobenius_map``; faster ``gf_ddf_shoup``
faster ``gf_irred_p_ben_or`` and ``gf_irred_p_rabin``
fixed bug in ``gf_frobenius_monomial_base``; faster ``gf_ddf_zassenhaus``;
eliminated ``expect`` keyword parameter; eliminated some special cases
