Add define to use file or not in testBlockedMpiChebyshev.cpp testBlockedMpiUniform.cpp and testFmmAlgorithmThreadProc.cpp

uniform kernel.

Before you'd have to split the total amount of particles between the
number of node ...

export tarball. Add check for time in python script. Small change in the
timer in the tests (not that much).

That way no need of using a file to exchange them. Split the mpi job in
two. Change a little bit informations printed in the job.

So we get average time of executing and test to check if the result is
good.

the changes are the new data layout, the deprecation of the POD cell
adaptors.

Changed tests are:
  - testBlockedAlgorithm,
  - testBlockedAlgorithmDyn,
  - testBlockedMpiAlgorithm,
  - testBlockedChebyshev,
  - testBlockedMpiChebyshev,
  - testBlockedRotation,
  - testBlockedRotationCompare,
  - testBlockedRotationMpi,
  - testBlockedSpeedOperators,
  - testBlockedTaylor,
  - testBlockedTree,
  - testBlockedUniform,
  - testBlockedUniformBench,
  - testBlockedUniformCompare

When using starpu number of threads should be given by env variables (and not command line parameter)
