Add an element to a dynamic array.
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.
| tab_ptr | pointer to the array to grow |
| nb_ptr | pointer to the number of elements in the array |
| elem | element to add |
Add an element to a dynamic array.
Function has the same functionality as av_dynarray_add(), but it doesn't free memory on fails. It returns error code instead and leave current buffer untouched.

Add an element of size elem_size to a dynamic array.

deliberately overlapping memcpy implementation
| dst | destination buffer |
| back | how many bytes back we start (the initial size of the overlapping window), must be > 0 |
| cnt | number of bytes to copy, must be >= 0 |
cnt > back is valid, this will copy the bytes we just copied, thus creating a repeating pattern with a period length of back.

Allocate a buffer, reusing the given one if large enough.
Contrary to av_fast_realloc the current buffer contents might not be preserved and on error the old buffer is freed, thus no special handling to avoid memleaks is necessary.
