This is a merge onto head of the last two months worth of changes to the networking code. There is individual change info on the branch arty_20040329. Here is a summary of what changed: tcpip: - Added a mostly working transport/tcp branch based on oskittcp (checked in at drivers/lib/oskittcp). This code shares almost nothing with the previous version. - Regularized IRP handling - Fixed ownership of buffers throughout tcpip.sys. Buffers are now required to be copied in a few more cases, but everybody can call anybody else and not have to worry about keeping a buffer alive for any specific reason. - Also moved lots more operations onto the stack (small datastructures and pointers). This will result in a further simplification of the code here. - Made each completion routine solely responsible for freeing memory from the corresponding action. - Removed reference counted small address structures in favor if inlines - Changed and clarified ownership rules almost everwhere - Fixed a few more type punning style errors - Added more info used by iphlpapi - Added some memory tracing stuff ndis: - Fixed one or two type punning errors ws2_32: - Added getservbyname and getprotobyname (partial) oskittcp: - Diagnostics everywhere - Eliminated dependence on raw_ip input - Simplified buffering and signalling model a bit - Added memory checking as in tcpip - more to come svn path=/trunk/; revision=9647

Ideas for optimizations:
* transmit.c (SendFragments, IPSendComplete):
Keep IPFRAGMENT_CONTEXT objects and PathMTU buffers in a pool
