This patch rearranges the code division between nd6.c and ip6.c such
that the latter does not need to access ND6-internal data structures
(specifically, "default_router_list") directly anymore.
The new function, while currently not used internally, allows external
code to clear the ND destination cache in the case that it may have
become inconsistent with the current situation, for example as the
result of a change of locally assigned addresses, or a change in
routing tables implemented through the LWIP_HOOK_ND6_GET_GW hook.
On failure, nd6_get_next_hop_entry() returns an ERR_ type negative
error code. ethip6_output() erroneously assumed that that error would
always be ERR_MEM, even though it may also be ERR_RTE in practice.
With this patch, ethip6_output() simply forwards the returned error.
ppp/utils.c: In function 'ppp_vslprintf':
ppp/utils.c:251:12: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
val = (unsigned long) va_arg(args, void *);

This is because a void* type is casted into an unsigned long type,
which obviously isn't correct on LLP64 systems such as Windows.
Actually, we are not using %p, thus we remove %p support completely
instead of trying to fix the issue in unused code.
The variable i is equal to q->len after exit the for loop.
Check the received data should not change the logic of update packet_idx.
So let's simplify the code a bit.

Art says:
pppos_input() can call ppp_input() which can call pppos_disconnect() to
disconnect the interface. However, it will continue to read in
characters and allocate a pbuf from the PBUF_POOL and keep it in
pppos->in_head and in_tail. When a re-connect happens and pppos_connect()
is called, this pppos->in_head and in_tail are zeroed, hence a memory
leak. (This happens with PPP_INPROC_IRQ_SAFE not defined.)
A fix would be inside pppos_input() to break out of the loop inputting
characters after calling ppp_input() if pppos->open == 0. Note that
the loop is not even entered if pppos->open == 0.
ppp_input(ppp, inp);
if(pppos->open == 0) //get out if they disconnected
break;
Fix it in a similar way which doesn't add new code by moving the
existing pppos->open check inside the byte loop.
