1918914598 PPP, PPPoS, removed linked list 
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 
Saving some RAM by using callbacks struct in rodata for required
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.

systems. Reduced types which were too large.

baaa2592a6 PPP, PPPoS, removed xmit_accm, almost duplicate of out_accm 
xmit_accm was meant to be a user configurable asyncmap, it was actually
broken since the introduction of ppp_new by the way we now reset the PPP
initial state, looks like no one until now is needing it anymore. If
necessary we will reintroduce this feature later properly instead of a
dirty and ugly hack into the PPP code.

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

ppp_pcb* and pppos_pcb*, fixed confusion with a strict naming for both.
