compute_z.h: Add an option structure for the MPI getrf nopiv algorithm to manage explicitely the communications and enforce a lookahead turnover in the communications

lapacke_dlamch: Add a chameleon wrapper to encapsulate and refactor the test on CHAMELEON_SIMULATION

context: Add a function to return the chameleon context in order to be able to use the public runtime API

zgetrf batched: Add an a field in the data structure and environment variable to define the batch size

compute/map: Improve the map function to take into account multiple descriptor and multiple implementations for the kernel to apply.

descriptor: Fix a major issue with global allocation in distributed and update comments in the structure for better understanding
