Zhenhua Zhang 588db02354 gatppp: Add PPP server extension 
1. Add interface to set PPP server info by g_at_ppp_set_server_info.
2. Pass local and peer address through IPCP handshaking.

Fix hardcode of ppp header size.

Kristen Carlson Accardi 2d8a1462db ppp: transition to dead when lcp finished 
Transition to DEAD when lcp is finished and ignore any io
disconnects if we are already dead.

Denis Kenzior 6d20194e75 ppp: Refactor connect / disconnect callbacks 
Right now it is very hard to figure out whether we should be calling the
connect callback or the disconnect callback.  So refactor as follows:
	- Connect callback is only called once the net is actually up
	- Disconnect callback is called once ppp is down, with a reason
	  for why it is so.

Denis Kenzior 9ae0dcb47d ppp: get rid of ppp_enter_phase 
This function simply didn't have the context of why the phase was being
entered.  Instead have each protocol notify GAtPPP as to what is
happening.  We already had this more or less for IPCP and AUTH events,
this just now formalizes it for LCP as well.

Kristen Carlson Accardi 9d5eb5110f ppp: transition to dead when read io destroyed 
remove call to signal_close for lcp object, it is redundent.  If
our io is destroyed we are dead, so transition the ppp phase to
DEAD so our disconnect callback can be called.

Denis Kenzior c9edf56fc6 ppp: Hang set_recording off the GAtPPP object 
Marcel: recording right now only works for PPP, so we'd need some sort
of multi-protocol support.

So for now expose set_recording to be used through the main PPP object.
HDLC object recording support needs to be extended.

Kristen Carlson Accardi a9c0be7339 ppp: use default ACCM when sending LCP codes 1-7 
According to the spec, you must transmit all Link Configuration,
Termination, and Code-Reject packets as if no options had been
negotiated.  This requires that when encoding we use the
default ACCM of 0xffffffff when sending these types of packets.

Kristen Carlson Accardi 71775550fe ppp: implement MRU option 
If the peer requests a MRU option, set the mtu for the network
phase.  When we are in link establishment phase, we should
continue to behave as if no option has been set and the peer
should use the default MRU.

This option is required for the Huawei E160G modem.

Denis Kenzior c8aa645973 ppp: Refing the channel is actually not necessary 
The read_watch and write_watches both take a ref

We will not support pfc or acfc

Denis Kenzior d1d73a75fc ppp: Introduce ppp_net_up_notify and use it 
This is slightly cleaner way than defining a weird callback function.

Denis Kenzior 42f6e8ec6e ppp: introduce ppp_auth_notify 
This function will be notified whenever authentication has succeeded /
failed.  This can happen in the authentication phase or during the
network phase.  If auth fails, then we should proceed to the terminate
phase.

Denis Kenzior e21bb72df0 ppp: Add set / get password & username 
Also refactor the set credentials function, we will be removing the auth
object shortly

Denis Kenzior fed99b9265 ppp: Transition the phase directly 
Use of the generate event function, while more 'pure' with regard to how
the spec views transitions, actually makes code more difficult to read.

Instead use phase transitions directly inside gatppp.  This still bleeds
through a little into lcp code, and probably should be fixed in a better
way eventually.

Denis Kenzior 9116b7e8f8 ppp: Let the upper layer handle open / up events 
This removes the need for the layer_started functions in lcp and ipcp.
For LCP the link is always up unless the socket has been closed, and for
IPCP the link should be opened as soon as LCP is ready anyway.

Denis Kenzior 843db6f9a5 ppp: unref should mean a hard shutdown 
This can happen when e.g. the modem is physically removed from the
system and it is not feasible to wait for the nice shutdown state to be
reached.
