Sergei Golubtsov c8ed7162d5 ppp: using RX ACCM = 0 by default 
Some modems such as Quectel EC200T do not honor the default value for
the Async-Control-Character-Map (ACCM) configuration option defined in
RFC 1548 6.2 as 0xffffffff. This patch suggests to use RX ACCM = 0 for
Ofono by default as pppd does for instance. This will reduce PPP data
overhead as well.

Philip Paeps a88662d23c gatchat: implement PAP authentication 
Make the authentication method configurable, CHAP or PAP, defaulting to
CHAP (i.e.: previous behaviour).

Implementation details:

 o If PAP is configured, we NAK the CHAP authentication protocol option
   in LCP configuration requests and suggest PAP instead.  This works
   around the amusing requirement of 3GPP TS 29.061 that modems must
   send a forced positive acknowledgement of the authentication method
   tried (i.e.: the modem will successfully accept any CHAP handshake,
   but if the network only supports PAP, the modem will hang up
   when it tries and fails to activate the PDP context)

 o The PAP Authenticate-Request is resent a hard-coded three times at
   ten-second intervals.  This may be a bit too persistent.  Chances
   are if it doesn't work the first time, it'll never work, but the
   RFC insists that we MUST retry.

Denis Kenzior 820b1f55c8 ppp: Refactor server-side API 
The biggest update here is that the server needs to be in dormant mode
by default, so as not to send a Configure-Req to the peer until the peer
is ready.  This requires adding special constructor for LCP to
initialize it to Stopped state instead of initial state.

Along with this, we pass the server local IP directly to the ppp server
constructor.

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 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 18e5e26acb ppp: Remove auth_ functions from ppp_auth.c 
These really serve no purpose right now as we use only CHAP.  So they
only take up space and make the code harder to read.  If we implement
1-3 auth protocols, then they're easier handled inside gatppp.c.  If we
have more, then a proper auth driver framework is required.

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 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 2c466c8baf Refactor: Get rid of packet handler registrations 
There are only about 4 protocols that the current ppp code handles and
it is doubtful that it will grow much more.  There's no point in having
an extensive packet handler registration framework.

Denis Kenzior cc1bb46ffa Refactor: Use GAtDisconnectFunc for ppp disconnect

ppp structure is most likely stored in user data anyway.
