Update: Ensure terminating NULLs, remove unnecessary arguments array, and cleanups.

Update: Ensure terminating NULLs, remove unnecessary arguments array, and cleanups.

Add additional terminate after calls.

The arguments array doesn't need to be an array of arguments.
Refactor it into a single value.

Change the data_make to be a pointer constant and relocate it in the function parameters order.

Deallocate the arguments when a child process is returning.

Allocation functions should use fake_default_allocation_small_d rather than F_memory_default_allocation_small_d.
