Creates a new GPtrArray with reserved_size pointers preallocated
and a reference count of 1. This avoids frequent reallocation, if
you are going to add many pointers to the array. Note however that
the size of the array is still 0. It also set element_free_func
for freeing each element when the array is destroyed either via
g_ptr_array_unref(), when g_ptr_array_free() is called with free_segment
set to TRUE or when removing elements.
