(backported to 2.2.4).
- FIX: Fixed timeout problem in the lwIP interface layer (bug 3302420)
(backported to 2.2.4).
- NEW: Added AVR implementation of the PAL driver contributed by Leszek.
(TODO: Update demos to use it)
- NEW: Added Eclipse project files to all makefile-based demos in order to
allow an easier import. The Eclipse workspace is assumed to be created
inside the ChibiOS/RT main directory.
