Removed unneeded precomp.h from drivers/lib/ip. Removed some memtrack and other spew. Removed datagram send pipe part, and accompanying address file queue. Simplified send pipe (major changes): - Neighbor is solely responsible for firing normal ip datagrams to the peer. - Transmit is the only place normal ip datagrams are passed to neighbor from. - Simplified fragmentation code. - Made callbacks explicit and always called in neighbor and transmit. - Clarified ownership of transmitted NdisPacket. - Ditto IPPackets here and in icmp. - PC(Packet)->DLComplete is *only* used by lan.c and loopback.c - Simplified loopback send mechanism Added the beginnings of a test suite svn path=/trunk/; revision=11582
