Unreferences the bytes, and returns a new mutable #GByteArray containing
the same byte data.
As an optimization, the byte data is transferred to the array without copying
if this was the last reference to bytes and bytes was created with
g_bytes_new(), g_bytes_new_take() or g_byte_array_free_to_bytes(). In all
other cases the data is copied.
