Convert the IpSecTransform from being a bi-directional pair of SAs to a unidirectional single SA. This CL also removes the concept of "direction from SAs meaning that a IpSecTransform may now be applied to a socket in either direction. -Make transforms unidirectional -Add Convert allocateSpi() to use destination rather than direction and remote address -Remove directionality from builders for IpSecTransform -Change applyTransportModeTransform() to take a direction in which to apply the transform object. -Additional minor naming updates -Restrict IpSecConfig to only print keys on eng builds -Move DIRECTION constants to IpSecManager -Add sourceAddress parameter to IpSecTransform to provide additional guarantees about the source address of data; (explicit failure rather than implicit failure). -Move SPI to the build() method of IpSecTransform Bug: 71717213 Test: runtest frameworks-net, CTS - IpSecManagerTest Change-Id: I0824b37f443f4b8c62536d9801238c63ed8f2a1c
