b957a81ea5 PPP, modified CHANGELOG about the previous large PPP rework
Done!, this is way better than before, I had this rework in mind
for a couple of years and I finally found the time to do it :-)

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.

4ad60b477c PPP, PPPoS, structure size optimisation

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.

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.

a5582e0960 PPP: re-order functions in the common sense API order
Re-order ppp.[ch] functions in the order functions should be called from
user application. Moved create functions, which actually return a PPP
control block before functions needing a PPP control block.

b4fe72c4a2 PPP: removed duplicated code in ppp_close()

consistent for all our low level protocol backends, cleaned
up duplicated code.

808098413c PPP: removed PPPoE and PPPoL2TP callback status notifier
Added necessary PPP core functions for PPPoE and PPPoL2TP status
notificaton (ppp_link_failed and ppp_link_end), removed callback,
low level protocol are now calling PPP core "link" functions.

74fd2dc9ad PPP: moved ppp_new() to low level protocol init for PPPoE and PPPoL2TP
First step of a rework of how low level protocols are using the
PPP core. Low level protocols are now going to use the core instead
of core using the low level protocols.

Final goal: separate PPP core code from low level protocols.

c8c0dc2f53 PPP: using a macro for ppp_set_default() instead of a function

17c6be6a9b PPP: removed ppp_delete(), merged with ppp_free()
The only benefit of ppp_delete() call was about having a persistent
netif interface. netif was moved out of PPP pcb so we don't need
ppp_delete() anymore, second step in simplifying the weird
new/open/free/delete PPP API.
