* Refactor some rpm variables to avoid collision
 * Replace %makeinstall macro according to official doc
 * Remove now inexistent mpi files
 * Allow to set the release number using "make deb/rpm RELEASE=n"

This will allow to define MIC_TASKSET_BIN or MIC_PATH.

It should be installed in 'bin' directory.

Offload slave process launch script now tries to find 'taskset' binary in /gpfs/scratch/bsc15/bsc15685/offload/ompss/15.06/nanox/intel64/bin directory when it cant be found in PATH.

Reworked all test generators. Now all AC_SUBST variables are replaced in generators by config.status script (it is launched after configure). This is the most straightforward, efficient and elegant way to do so, as we avoid to substitute manually all of them using sed in a Makefile.

Added missing -lm in mcc-openmp-generator.in

MPI Comm Spawn now "lazy-inits" threads
Multiple performance improvements in MPI Offload 

By now, this approach is only used by CUDA.

Fix MPI Offload compilation in some machines

Enable MPI test (should work now), rename a few files, add instrumentation helper script for offloading (temporary until extrae auto-merges offload traces) and do a few other changes

Make MPI offload compatible with newer SMPPlugin

Improve support for other MPI (non-MPICH/Intel) implementations, Fortran communicators are now translated between C and Fortran.
