Syslinux - Apr 2011 - Now available for testing: lwIP for PXELINUX

Eric Biederman has taken the work I did almost two years ago to port
lwIP to Syslinux, and actually gotten it to the point where it is
integrated into the filesystem stack and *working*.

As such, I have pushed out a new branch "lwip" to the git repository,
for testing purposes, and I have made a 4.10-pre1 prerelease which
includes this code.

I don't think it is ready for prime time yet, but I would be *very*
interested in hearing people's experiences with it.  It currently
supports tftp and http; we will probably be adding ftp shortly.

TFTP transfers seem to be way slower with syslinux-4.10-pre1-1-gf5203bf
compared to syslinux-4.04-8-gece69c7 on Bochs. Used to be ~10 seconds
for 3.8 MB and now it's 2 minutes and 33 seconds.

Is the intention that this replace gpxe/gpxelinux*.0 for the most
part?  It seems that client-side scripting (LUA is present but the
last I checked it seemed more of a WIP), SAN protocols and HTTPS will
be the only things missing shortly.

Looks as fast as without lwip now.
