Improvements to the assembler interface that let us move chunks of the

site and s loop into the kernels. This will save on function call overhead and
guarantee L2 prefetching strategy is right since OMP can't distribute the
sub-chunks of work.

Fixes to fermion force terms after sign of gamma_mu (0...3) change.

Thought I had already committed these.
Believe I have got the Gparity fermion force working.
* tests/Test_gpdwf_force.cc -- correctly predicts dS for two flavour pseudofermion
based on a small dt update of U field.
* tests/Test_hmc_EODWFRatio_Gparity.cc -- ran 1 trajectory on 8^4 with dH=0.21.
Need to accumulate a full plaquette log to believe fully which will take some hours of run time.

* Finished the template/policy style introduction of gparity, except the gparity force terms.
...
So valence sector looks ok.
FermionOperatorImpl.h provides the policy classes.
Expect HMC will introduce a smearing policy and a fermion representation change policy template
param. Will also probably need multi-precision work.
* HMC is running even-odd and non-checkerboarded (checked 4^4 wilson fermion/wilson gauge).
There appears to be a bug in the multi-level integrator -- <e-dH> passes with single level but
not with multi-level.
In any case there looks to be quite a bit to clean up.
This is the "const det" style implementation that is not appropriate yet for clover since
it assumes that Mee is indept of the gauge fields. Easily fixed in future.
