*adapt Householder to the convention that we now favor refs over ptrs for output. Keep "workspace" as pointer because it is an array (which is now more obvious).
...
*rename makeHouseholderSequence to householderSequence, because that's what it returns.

Added private, non-implemented assignment operators to functions that don't need them (fixes VC warning on /W4).

* add a HouseholderSequence class (not good enough yet for Triadiagonalization and HessenbergDecomposition)
...
* rework a bit AnyMatrixBase, and mobe it to a separate file

fix bug: with complex matrices, the condition (ei_imag(c0)==RealScalar(0)) being wrong could bypass the other condition in the &&.
...
at least that's my explanation why the test_lu was often failing on complex matrices (it uses that via createRandomMatrixOfRank)
and why that's fixed by this diff.
also gcc 4.4 gave a warning about tailSqNorm potentially uninitialized

and add Gael a (c) line in Householder.h
