We can get rid of the view pool for SDU segments :) We have to make the code slightly more complex :'( The basic idea is always giving the original SDU buffer to `conn.c` for it to pull ACL fragments from. In order to do this, we need to add the PDU headers just-in-time. `bt_l2cap_send_pdu()` does not add them before putting the PDU on the queue anymore. They are added by `l2cap_data_pull()` right before the data leaves `l2cap.c` for `conn.c`. We also have to inform `conn.c` "out of band" of the real L2CAP PDU size so it doesn't fragment across segment boundaries. This oob is the new `length` parameter to the `.pull()` method. This is the added complexity mentioned above. Since SDU segmentation concerns only LE-L2CAP, ISO and Classic L2CAP don't need this extra logic.
