VJ support is known to be broken when built with some compiler
optimizations enabled, disabling it by default until someone needs it
and fixes it.
It was mostly used with dial-up modems, it is useless with PPPoE and
PPPoL2TP and is probably useless as well with cellular modems, so
disabling it by default makes sense anyway.
* LWIP_MARK_TCPIP_THREAD moved to include/lwip/sys.h
* Unix port macro definitions moved to sys_arch.h
* LWIP_MARK_TCPIP_THREAD
* LOCK_TCPIP_CORE
* UNLOCK_TCPIP_CORE
(goldsimon@gmx.de: fixed unix Makefile build and win32 build)

By defining LWIP_PLATFORM_ASSERT to a function, we can prevent arch.h
from including stdio.h and stdlib.h
