simplify memory management
This change replaces pointers with automatic arrays to greatly simplify
the memory management in the main subroutine:

  - All arrays are defined in a single location and with their final
    dimension explicitely shown.

  - The allocation/deallocation is performed automatically when
    entering/leaving the gray_main routine.
