Fix issue in legendre_matsubara

Removed parenthesis.

Add a cython proxy for c++ views

Added a small proxy for c++ views. It has a default
constructor which constructs a view on the default non_view
type. The equal sign has a value meaning (rebind) for this
proxy and the << is used to fill a view. This allows to have
a non-ambiguous transfer to cython.

Remove old Green's functions from ctqmc_hyb solver

At this stage the old Green's functions are not in the solver
anymore. The ctqmc_solver.pyx still has the old GF so that tests
are easy to pass and check. Some cleaning in the code.
