My best guess is that there's something wrong with the threading in the 
windows port (by now).
I have short term plans in adding assertion checks for these kind of 
errors, but I'm not there yet.
For now, just check that 'ppp_input()' is called from tcpip_thread, not 
from the main loop thread.

In other words, when using the contrib windows example, 
PPP_INPROC_IRQ_SAFE should be 1.

This is wrong. It's only a flag check, but still, netif functions are 
not to be called from API threads or IRQs.
From a quick look, the rest seems OK.
