array: allow arbitrarily sized array elements

There exist two typical ways to use an array:

 1) to hold pointers to externally allocated memory regions

    Use array_init(...) for initialization, an element has the
    size of a pointer. Use the functions suffixed with `_ptr'
    to manage your pointers. The cleanup function array_release_full
    must only be used with this type of array.

 2) to hold arbitrary sized objects

    Use array_init_sized(...) to specify the size of a single
    element. Use the regular (i.e. without the `_ptr' suffix)
    functions to manage your objects. array_get will return a
    pointer to the object stored within the array.
