Update the RTEMS port of LWIP.  Provide reproducible test cases so we can be sure it stays in working condition. See discussion on [wiki:https://www.rtems.org/pr1712 PR1712]

A goal of this effort is to be able to use the standard TCP/IP NIC drivers already in RTEMS.  If this is feasible, then a user could switch between the full-featured BSD TCP/IP stack in RTEMS or the LWIP stack to save memory at the expense of reduced functionality.

The work would have to do :
1. start with current LWIP source
1. update the port for [http://git.rtems.org/rtems/snapshot/rtems-4.10.2.tar.bz2 current RTEMS] and [http://download.savannah.gnu.org/releases/lwip/ current LWIP]
1. make the port portable across CPU architectures and BSPs (This is usually not as hard as it sounds.)
1. Provide documentation and examples that run on at least [http://www.rtems.org/wiki/index.php/QEMU qemu] so others can provide feedback.
1. Ideally use the standard BSD NIC drivers if at all technically possible so when you write a driver for one TCP/IP stack, you automatically get it for both stacks in RTEMS.
