apply changes r52501 for lwIP branch
- Fix binding to an unspecified port on a connect so that it works reliably by asking the TCP library for a free port instead of assuming that one we have is free
- Fix binding to an unspecified port on a listen which previously would result in the address file not having information stored about the port number assigned
- Fix a nasty bug which resulted in us binding to an arbitrary port during a connect even when the client wanted a specific port

- Hold on to the disconnect IRP until all pending sending IRPs are sent to the transport driver if a controlled disconnect was requested (merge of r52415)
[TCPIP]
- add some mroe debug statements to track new current sync problem
- remove some old debug statements that are useless now
[lwIP]
- add some mroe debug statements to track new current sync problem

[FORMATTING]
This is just a code formatting phase. I reordered some of the code and put some debugging DbgPrint-s in order to help understand the control and data flow. Working on trying to stop the system from crashing when server socket gets closed.
svn path=/branches/GSoC_2011/TcpIpDriver/; revision=52042
Closing a socket while in listening state (that has not accepted any connections) no longer certainly crashes the system. There's still a tendency to crash the system sometimes, but it's related to possibly not canceling any outstanding IRPs for the listening socket.

Fixed an error in the accepting code (in rostcp.c line 576). tcp_accepted was being called for the wrong pcb. Instead of the pcb belonging to the listening socket it was being called for the pcb belonging to the newly created connection socket. In order to fix this I added an extra field to the tcp_pcb structure to hold a reference to the listening socket. This is a crude method and it will be replaced by something more elegant.
Right now however there's a slight nondeterminism regarding the connection. One it's established the message either gets through to the other side or not, randomly. This could be due to a race condition of some sorts.
Also another problem is that the server side brings down the system when closing.
svn path=/branches/GSoC_2011/TcpIpDriver/; revision=51889
- Rewrite most of the lower TCP layer code to work with lwIP
[LWIP]
- Write all of the implementation-specific code and headers
[TCPIP]
- Add assertions in the object reference functions
- Remove the completion queue hack
This is still isn't totally finished yet. There are still two main issues that need to be overcome: listen/accept don't work at all and the performance is horrible.
I hope that once I tune some of the options, I can get it to perform reasonably well. If any curious testers want to try this out, be my guest but realize that not
a lot of apps will work yet. Suggestions are welcome! :)
