It is intended to approximate TCP behaviour. It is invoked through batctl: the protocol is connection oriented, with cumulative acknowledgment and a dynamic-size sliding window. The test *can* be interrupted by batctl. A receiver side timeout avoids unlimited waitings for sender packets: after one second of inactivity, the receiver abort the ongoing test.

Split the API in subobjects in order to improve definition readability. At the same time, remove the "bat_" prefix from the API object and its fields names. These are batman-adv private structs and there is no need to always prepend such prefix, which only makes function invocations much much longer.
