e39d012312 PPP, from PPPD upstream, separate IPv6 handling for sifup/sifdown 
The current code is buggy regarding handling of link state when using
both IPCP and IPv6CP: if IPv6CP has been set up and if during IPCP
negociation, ipcp_up() fails, it will incorrectly take the interface
down. The simple solution here is to change the platform code to do the
same as on Solaris: separate IPv6CP up/down state handling with sif6up()
and sif6down(), so that we really know when the interface is allowed to
go down.

(Based from pppd commit b04d2dc6df5c6b5650fea44250d58757ee3dac4a)

7fe7e1e984 Merge branch 'ppp-new' 
Based from pppd 2.4.5, released 2009-11-17, with huge changes to match
code size and memory requirements for embedded devices, including:
- Gluing together the previous low-level PPP code in lwIP to pppd 2.4.5, which
  is more or less what pppd sys-* files are, so that we get something working
  using the unix port.
- Merged some patchs from lwIP Git repository which add interesting features
  or fix bugs.
- Merged some patchs from Debian pppd package which add interesting features
  or fix bugs.
- Ported PPP timeout handling to the lwIP timers system
- Disabled all the PPP code using filesystem access, replaced in necessary cases
  to configuration variables.
- Disabled all the PPP code forking processes.
- Removed IPX support, lwIP does not support IPX.
- Ported and improved random module from the previous PPP port.
- Removed samba TDB (file-driven database) usage, because it needs a filesystem.
- MS-CHAP required a DES implementation, we added the latest PolarSSL DES
  implementation which is under a BSD-ish license.
- Also switched to PolarSSL MD4,MD5,SHA1 implementations, which are meant to be
  used in embedded devices with reduced memory footprint.
- Removed PPP configuration file parsing support.
- Added macro definition EAP_SUPPORT to make EAP support optional.
- Added macro definition CHAP_SUPPORT to make CHAP support optional.
- Added macro definition MSCHAP_SUPPORT to make MSCHAP support optional.
- Added macro definition PAP_SUPPORT to make PAP support optional.
- Cleared all Linux syscall calls.
- Disabled demand support using a macro, so that it can be ported later.
- Disabled ECP support using a macro, so that it can be ported later.
- Disabled CCP support using a macro, so that it can be ported later.
- Disabled CBCP support using a macro, so that it can be ported later.
- Disabled LQR support using a macro, so that it can be ported later.
- Print packet debug feature optional, through PRINTPKT_SUPPORT
- Removed POSIX signal usage.
- Fully ported PPPoS code from the previous port.
- Fully ported PPPoE code from the previous port.
- Fully ported VJ compression protocol code from the previous port.
- Removed all malloc()/free() use from PPP, replaced by stack usage or PBUF.
- Disabled PPP server support using a macro, so that it can be ported later.
- Switched all PPP debug to lwIP debug system.
- Created PPP Control Block (PPP PCB), removed PPP unit integer everywhere,
  removed all global variables everywhere, did everything necessary for
  the PPP stack to support more than one PPP session (pppd only support
  one session per process).
- Removed the statically allocated output buffer, now using PBUF.
- Improved structure size of all PPP modules, deep analyze of code to reduce
  variables size to the bare minimum. Switched all boolean type (char type in
  most architecture) to compiler generated bitfields.
- Added PPP IPv6 support, glued lwIP IPv6 support to PPP.
- Now using a persistent netif interface which can then be used in lwIP
  functions requiring a netif.
- Now initializing PPP in lwip_init() function.
- Reworked completely the PPP state machine, so that we don't end up in
  anymore in inconsistent state, especially with PPPoE.
- Improved the way we handle PPP reconnection after disconnect, cleaning
  everything required so that we start the PPP connection again from a
  clean state.
- Added PPP holdoff support, allow the lwIP user to wait a little bit before
  reconnecting, prevents connection flood, especially when using PPPoL2TP.
- Added PPPoL2TP LAC support (a.k.a. UDP tunnels), adding a VPN client
  feature to lwIP, L2TP being a widely used tunnel protocol.
- Switched all used PPP types to lwIP types (u8t, u16t, u32t, ...)
- Added PPP API "sequential" thread-safe API, based from NETIFAPI.

25e398a8f0 PPP, from PPPD upstream, accept IPCP ConfAck packets containing MS-WINS options 
pppd: Accept IPCP ConfAck packets containing MS-WINS options

Since last week I'm seeing IPCP negotiations going like this (and
eventually failing) when connecting to my ISP:

Jul 11 20:03:25 * pppd[4833]: sent [IPCP ConfReq id=0x2 <addr 0.0.0.0> <ms-dns1
0.0.0.0> <ms-dns2 0.0.0.0>]
Jul 11 20:03:26 * pppd[4833]: sent [IPCP ConfReq id=0x2 <addr 0.0.0.0> <ms-dns1

Jul 11 20:03:26 * pppd[4833]: rcvd [IPCP ConfNak id=0x2 <addr 10.167.246.198>

Jul 11 20:03:26 * pppd[4833]: sent [IPCP ConfReq id=0x3 <addr 10.167.246.198>

<ms-dns1 213.162.69.1> <ms-dns2 213.162.69.169> <ms-wins 124.6.168.55> <ms-wins

Jul 11 20:03:27 * pppd[4833]: sent [IPCP ConfReq id=0x3 <addr 10.167.246.198>

17.17.17.17>]
...

with the last two lines repeating until the IPCP error limit is
reached. As you can see, the peer added two extra fields in the
ConfNak reply. This is allowed, and indeed the following sent
ConfReq packet reflects this. However, when the ConfAck packet
is received, pppd discards it as invalid, because of the ms-wins
fields.

This fixes it.

This patch adds support for RFC3542-style checksum computation on raw,
IPv6 sockets via the IPV6_CHECKSUM socket option.

This allows the development of application-layer utilities such as
ping6 which are unable to compute the raw packet checksum without a
prior knowledge of the source address selection.

38bfe50508 Fixed size calculation in MALLOC memory pool creation macro. 
The LWIP_MALLOC_MEMPOOL macro needs to use the aligned size of the
memp_malloc_helper structure, since mem_alloc() uses it to calculate
the required pool element size. If LWIP_MEM_ALIGN_SIZE(x) is redefined
to align to something larger than 4, then in some cases
the current code can lead to unexpected mem_alloc() failures.
For example:
    #define LWIP_MEM_ALIGN_SIZE(size)       (((size) + 31) & ~31)
and the largest MALLOC pool is of size 60 bytes, e.g.:
    #define LWIP_MALLOC_MEMPOOL(256, 60)
then the following call:
    mem_malloc(58)
will cause an assertion.

252abbeb8d make timeouts usable reliably from outside of the timeout routine 
although timeouts are relative to timeouts_last_time (transitively by
addition to the time values of their predecessors, if there are any),
sys_timeout does not compensate for that; as a result, timeouts fire too
early unless invoked from within a timeout handler (when
timeouts_last_time == now).

4fda366b67 PPP, added PPP notify phase support 
PPP notify phase support, using compile-time PPP_NOTIFY_PHASE macro.

This can be used for example to set a LED pattern depending on the
current phase of the PPP session.

Callback example:

static void ppp_notify_phase_cb(ppp_pcb *pcb, u8_t phase, void *ctx) {
  switch(phase) {
      case PPP_PHASE_DEAD:  /* Kept off */
      case PPP_PHASE_MASTER:
        /* LED Off */
        break;
      case PPP_PHASE_INITIALIZE:  /* Session opened */
        /* LED FastBlink */
        break;
      case PPP_PHASE_RUNNING:  /* Session running */
        /* LED On */
        break;
      default:
        /* LED SlowBlink */
   }

2ceae6014e PPP, reduced by one buffer PPPoS RX requirements in multithreaded context 
Removed one unecessary allocated PBUF per PPPoS RX packet if PPP_INPROC_MULTITHREADED is set by adding the necessary data for
pppos_input_callback() in front of the first pbuf instead of allocating a new buffer.

2350d941a5 PPP, added PPP_USE_PBUF_RAM compile time option 
pbuf_type PPP is using for LCP, PAP, CHAP, EAP, IPCP and IP6CP packets.

Memory allocated must be single buffered for PPP to works, it requires pbuf
that are not going to be chained when allocated. This requires setting
PBUF_POOL_BUFSIZE to at least 512 bytes, which is quite huge for small systems.

Setting PPP_USE_PBUF_RAM to 1 makes PPP use memory from heap where continuous
buffers are required, allowing you to use a smaller PBUF_POOL_BUFSIZE.

25f9f55878 PPP, removed PPP_INPROC_OWNTHREAD feature, which almost only make things harder 
I consider to remove the PPP_INPROC_OWNTHREAD crap in ppp-new,
as said in bugs #37278 and #37353.

1. It requires the ppp_input_thread() function to be modified to match
user system, like some did by adding the vTaskDelete(NULL); FreeRTOS
call at the end of the function, for example.

This is a tiny-tiny fonction that should be, in my opinion, on the user
port, like the Ethernet input thread we see in many Ethernet port.

2. It is actually not that thread safe.

2.1. pcb->phase IS modified by the lwIP core thread so it should at
least be set to volatile, otherwise the pcb->phase copy may live
indefinitely in CPU register. It works because of the sio_read()
function call which without doubt flush pcb->phase copy from CPU
register. I dont want to set ppp_pcb struct to volatile for obvious
performance reasons.

2.2. This function assume PCB still exists whatever is happening, which
is not the case after you called ppp_delete() function outside of this
thread. If sio_read() is blocking waiting data and pcb destroyed, it is
going to read a deallocated pcb which luckily should still have
pcb->phase set to 0 (=PHASE_DEAD) due to preallocated "control block"
structures of lwIP. Even with sio_read_abort(), there might be timings
issue due to a lack of a synchronization mechanism.

3. I dislike the sys_msleep(1), it means that systems should have at
least a 11 chr buffer at 115200/10 byte/s, and bigger with higher serial
speed, for example with 3G/HSDPA modems accessed through SPI, at 20
Mbits/s this is a ~2000 bytes buffer required to keep incoming data
during this sleep, I don't see why we require systems to do so,
sio_read() should obviously be a blocking call. I cannot easily
remove this sleep because some systems might have wrongfully used this
call as a CPU idle feature with a non blocking sio_read() call.

0eb83f6ee6 PPP, IAR EWARM won't compile ppp-new due to keyword clash 
The word "class" is reserved in IAR's EWARM compiler since it looks like c++.
This causes a failure to compile in the lcp code.

Arguably it is a bug in the compiler, but it is easy to work around with a
name change in the lcp.[ch] code. I fixed it by changing "class" to "class_".

The lwIP PPP support is based from pppd 2.4.5 (http://ppp.samba.org) with
huge changes to match code size and memory requirements for embedded devices.

Anyway, pppd has a mature codebase for years and the average commit count
is getting low on their Git repositories, meaning that we can follow what
is happening on their side and merge what is relevant for lwIP.

So, here is the pppd follow up, so that we don't get away too far from pppd.

35c670513f fixed some more PPP phase state machine issues 
The only way PPPoE or PPPoL2TP disconnect it through ppp_link_terminated(),
therefore PPP is always already down, so we don't need to ask PPP to hup or stop.

8ec92b6fe7 don't call ppp_hup() and ppp_stop() if PPPoE or PPPoL2TP failed to connect 
This is useless because PPP is not started yet, it confuses the PPP phase
state machine.

3c122117fc improved PPP API, added ppp_reopen() 
This is now the user choice to re-establish the session in the link status callback
by either calling the ppp_reopen() to re-establish or ppp_delete() to free the PPP
control block. Without user intervention, the PPP control block now stay in the dead
phase, allowing the user to re-establish or delete the control block later.

11a3057e8e PPP: Add option to skip FCS table 
Option PPP_FCS_TABLE is created which controls if PPPoS FCS calculation
should be done against precalculated table or by using a short algorithm.

Default value is 1, keeps old behaviour.
Setting it to 0 saves around 0.5 kB flash.
