The array to grow is supposed to be an array of pointers to
structures, and the element to add must be a pointer to an already
allocated structure.
The array is reallocated when its size reaches powers of 2.
Therefore, the amortized cost of adding an element is constant.
In case of success, the pointer to the array is updated in order to
point to the new grown array, and the number pointed to by nb_ptr
is incremented.
In case of failure, the array is freed, *tab_ptr is set to NULL and
*nb_ptr is set to 0.
@param[in,out] tab_ptr Pointer to the array to grow
@param[in,out] nb_ptr Pointer to the number of elements in the array
@paramin elem Element to add
