- use (starpu_cpu_func_t) 1 trick, same as cuda_func
    - cpu funtions are not defined anymore avoiding the dependency to coreblas
    - add #if !defined(CHAMELEON_SIMULATION) where it is needed
    - remove dependency to the coreblas library (become useless)
    - remove useless simucblas, simulapacke libraries
    - remove CHAMELEON_SIMULATION_MAGMA cmake variable and definition
      - keep using CHAMELEON_USE_CUDA and CHAMELEON_USE_MAGMA to consider CUDA kernels
      - this avoid to introduce useless new variables
    - work on messages

to change the default values for tag_width(=31) and tag_sep(=24).
Today, it serves only with starPU.

MPI tag upper bound: MPI_TAG_UB is included (so on most platform the default values tag_width=31, tag_sep=24 are ok)

chameleon: add a out_of_core example, requires to handle the case where starpu handles itself the allocation of tiles -> we give a NULL pointer through the get_blkaddr function for registering

Fix a large bunch of warnings, and there are still mistakes that should be fixed before the SC release

change the way we include our own header files --> relative to the root - when plasma is in the same env, chameleon can take some headers not belonging to it (ex: #include descriptor.h, this file states in plasma install dir also) which make compilation errors

change copyright - correct whitespace - place cmake module depending on chameleon in cmake_modules and no more in cmake_modules/morse
