Add MORSE_Desc_Create_OOC, which is like MORSE_Desc_Create, but does not
actually allocate a matrix, thus letting the runtime allocate on-demand the
tiles, possibly pushing them to the disk.

Add a --ooc option to tests to enable this.

    - 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

The new codelet is added for all 3 runtimes but only tested with starpu ;-)
An example test7 is added : it is a copy of test6 that uses the new function to build the matrices

ooc test: create a ooc subdirectory in the build dir to write data on disk instead of /tmp/starpu_ooc because we must guarantee that the directory exists

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

At the user levl, we wait for a sequence. We need to add a MORSE_Barrier function that waits for all sequences currently running

instead of introducing RUNTIME_distributed_barrier

add cudablas library to make calls to cuda kernels (magma here, cublas will follow), no more calls to magma in runtime/starpu codelets

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 installation directories for headers, executables and docs. Make it relative to chameleon to avoid a bloody mess in system dirs

MORSE_Desc_Create_User with NULL pointer cannot be used to allocate the data (mat) - when NULL is given to MORSE_Desc_Create_User means that the application manage the allocation - to let MORSE allocate its data -> use MORSE_Desc_Create with NULL pointer

do not allocate a matrix if NULL pointer is given for mat in MORSE_Desc_Create_User --> let the user manage the allocation of his data

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