lwip 1.3.2 port

[Simon Kallweit <simon dot kallweit at intefo dot ch>]

Hi John,
Hi Ganesh

Nice to hear that you are using the lwip stack and it is working fine 
for you. Currently, I hold the lwip code in my own git repo, shared with 
other changes I have done to eCos. The plan was to get my current lwip 
code into the CVS. John, I think it's about time to get this done. I can 
do one latest merge with the lwip 1.3.2 codebase and then we should be 
ready.

I still have some local changes concerning ppp in my repo (which are 
absolutely necessary in my current project). But I think we should keep 
these changes in for a while. It seems like some work is done in the 
official lwip repo, concerning ppp. But these changes will only be 
available in future 1.4.x releases. The current stable release is 1.3.2, 
and will be for a little while. When we get to a stable 1.4.x release, 
it may be a good time to get back to the lwip repositories ppp code. In 
the meanwhile, I'll keep track of what's happening in the official repo 
and try to incorporate my changes into the official repo (support for 
ppp in a single-threaded lwip environment).

What do you think?
