ea58a8103c PPP, PPPoS, fixed thread safety of pppos_input() 
PPPoS was actually not thread safe, pppos_input() can be called from
lwIP user port at any time, whatever the PPP state is. It might even be
called during pppos_connect() and pppos_listen(), this is quite unlikely
the port do that but nothing prevent the user to since we document
pppos_input() as being thread safe.

Added a mutex if PPP_INPROC_MULTITHREADED is set and ensure pppos_input()
is safe in regard to other pppos_* functions.

2aabe16163 PPP, PPPoS, removed ppp_accm_mask[], saved a few bytes of ROM 
This was a pretty naive way of doing a bitshift, code is smaller if we let
the compiler decide.

b0b7240022 PPP, PPPoS, moved advise about modem from pppos_create() to ppp_open() 
pppos_create() can be called whether the modem is ready to process the
PPP session since pppos_create() does not start the PPP session anymore,
moved the advise from pppos_create() to ppp_open().

We don't need anymore the PPPoS linked list since we have callbacks
for everything.

b92fe3eecb PPP, CORE, new callbacks, send_config, recv_config, vj_config 
Removed some calls from PPP core to PPPoS low level protocols,
the const struct allows us to have more and more callbacks
without using more RAM.

985de035bc PPP, CORE, now using const callbacks struct from lower level protocols

callbacks called by PPP core to PPP low level protocols.

f511bec26c PPP, PPPoS, only check PPPoS PCB pointer if PPPoS is not the only enabled lower protocol 
We only need to keep track of existing PPPoS interfaces if PPPoS
is not the only enabled protocol.

PPP CORE does not have callbacks pointers for all PPPoS callbacks
which should actually be required for PPPoS (VJ config, asyncmap, ...),
there is too much callbacks to create and PPPoS must be kept light,
especially for users who are only using PPPoS.

But there is a drawback, PPP CORE does not know which
lower protocols it is talking to thanks to the abstraction,
therefore if PPPoS is enabled as well as PPPoE or PPPoL2TP there
might be situation where PPP CORE calls pppos_ config functions
on interfaces which are NOT PPPoS one. This is very unlikely to
happen because protocols not supported by PPPoE or PPPoL2TP are
disabled at LCP/IPCP negotiation but we are better safe than sorry.

So we check if passed PPP pointer to PPPoS configuration functions
is a PPPoS interface by checking against a linked list of existing
PPPoS interfaces.

8a8cba75a2 PPP, lower protocols, chained returns from local functions to callback caller 
PPPoS,PPPoE,PPPoL2TP functions using non-void returns are now propagated
to callback caller (PPP core).

1ae3808e13 PPP, CORE, prepared for lower protocols callbacks returning state 
Until now, callbacks used void return, preparing callbacks to return
PPPERR_ status.

or PPPoL2TP.

cfe04d4453 PPP, PPPoS, using PPPoS PCB pointer on VJ and pppos_ configuration functions 
Slightly more consistent this way, and prevent using link_ctx_cb pointer
from PPPoS protocol file.

f98f2890f3 PPP, PPPoS, check if PPPoS configuration functions are used on PPPoS 
We don't have callbacks which can be set or cleared for PPPoS
configuration, there is too much callbacks to create and PPPoS must be
kept light, therefore PPPoS functions can be called when PPP core
configure a PPPoE or PPPoL2TP interface, this is very unlikely to
happens because protocols not supported by PPPoE or PPPoL2TP are
disabled at LCP/IPCP negotiation but being safe is still better.

Check if passed PPP pointer to PPPoS configuration functions is a PPPoS
interface by using a linked list of exiting PPPoS interfaces.

2b9d304816 PPP, PPPoS, renamed *sc pointer to *pppos, renamed *pcb pointers to *pppos and *ppp 
It was a bit confusing and error prone having *pcb pointers for both
ppp_pcb* and pppos_pcb*, fixed confusion with a strict naming for both.

ea205f2fcd PPP, add PPPoS CB for PPPoS private data 
Created a new PPPoS CB going to have PPPoS private data, so allocating a
PPPoE or a PPPoL2TP interface does not allocate as well PPPoS variables.
