This buffer can be alternatively own or external

When buffer is own, resize and reinit operations conduce to reallocation only if size differ.

When restored (via serialization), an already initialized buffer will try to match restored data with its buffer.

For an external buffer :
- a send operation (of type save this then restore other) will conduce to the creation of an own buffer (provided buffer is not already an external) since there is no guaranty that external data is stored on the same computer.
- a receive operation (of type save other then restore this) will simply copy received data to external location. In this case, if data type or size mismatch an error will be thrown
For a own buffer :
- a send operation (of type save this then restore other) will conduce to the creation of an own buffer (provided buffer is not already an external) and copy data.
- a receive operation (of type save other then restore this) will simply copy received data to external location. In this case, buffer is resized if needed
