synthethize_outgoing_call was only used once from dial_handle_result.
So move all the logic of registering the call to D-Bus and adding it to
the voicecalls list to that function.
This will allow synthethize_outgoing_call to be used from other
callbacks where the dial callback is guaranteed to return before any
call state notifications, e.g. in the case of +BLDN.

It's also necessary to add additional references to the sources
for the duration of the dispatch_sources loop because any source
can be removed when any callback is invoked (and not necessarily
the one being dispatched).
The Quectel EC21 does not provide the SMS PDU on the message event
notification.
This patch adds a call to 'raw read' on the message ID from the event
notification if the event notification does not already contain the
message data.
The message data begins with the SMSC length, type, and address so
the TPDU length is adjusted accordingly in the raw_read callback. This
differs from the way the raw message data is handled in the case
that it is included in the event notification itself. As I don't have
access to any other QMI modem at this time, I'm can not confirm that
this difference is reasonable.
Implemented the core API's needed for sim-auth:
list_apps: already implemented
open_channel: Opens a logical channel with +CCHO
close_channel: Closes logical channel with +CCHC
logical_access: Access an opened channel with +CGLA
The sim-auth module atom can now be used for SIM application discovery
and authentication. The atom will automatically discover SIM
applications available on the SIM and register a new DBus object under
the modem, whos name is the AID string e.g.
/modem1/A0000000871004FFFFFFFF8906190000
A list of discovered AID object paths and types can be retrieved by
calling GetApplications() under the modems (new)
org.ofono.SimAuthentication interface which returns "a{oa{sv}}" where
o = path (e.g. above)
and the dictionary contains the following properties:
Type: "Umts" or "Ims"
Name: "USim" or "ISim"
The Type signifies which interfaces the AID object will have:
Umts = org.ofono.USimApplication
Ims = org.ofono.ISimApplication
These interfaces will contain the supported USIM/ISIM authentication
algorithms. Where:
org.ofono.USimApplication has:
GetProperties()
GsmAuthenticate()
UmtsAuthenticate()
org.ofono.ISimApplication has:
GetProperties()
ImsAuthenticate()
Added new dbus interfaces for SimAuth module as well as
function prototype definitions to simauth header.
org.ofono.SimAuthentication:
Interface to hold the auth object to type mapping property
org.ofono.USimApplication:
Application with USim functionality (GSM/UMTS auth)
org.ofono.ISimApplication:
Application with ISim functionality (IMS auth)
The existing service check API takes both SST and UST services
and could inadvertently return success on a service if one
(SST or UST) service did not exist. This adds an API specifically
for checking for a UST service, and if the UST dir is not available
it will return FALSE, rather than possibly returning true on some
other SST service.
Parsing a SIM application only copied the 16 byte AID
portion, which included the application type. Parsing out
the type makes sorting much easier for modules using the
parser.
The nokia-gpio plugin should not try to create symlinks to relevant gpio
pins under /dev/cmt, since the location it is looking is no longer
correct on newer kernels and it might change again in the future. This
patch removes code from nokia-gpio that tries to create a symlink.
Users will now need to symlink the modem gpios to /dev/cmt themselves.
On the 4.13 kernel, this can be done by, for example, adding a udev rule
to:
# ln -sf /sys/bus/hsi/devices/n900-modem /dev/cmt
The HUP results in errors in gatio which will deref parts
of the AT channel. This makes it impossible to recover and
send further AT commands after the HUP.
