This fix is similar to the one in the following commit,
but fixes allocation for context ids after ap's are
read from settings.

gprs: Fix allocation of context id
While adding the sim pin cache feature, pin_name could cause issue in
cases when sim pin is not there.

This patch allows a driver to set the interface only once, instead of at
every context activation. The previous way was originally designed for
PPP and RAW_IP based contexts which would have a (potentially)
differently named interface after each context activation due to use of
TUN/TAP. This also worked for static high-speed interface setups as
well, since these usually had a single interface only.
For devices that support multiple high-speed interfaces it would be
advantageous to have each gprs_context get an interface assignment right
in the modem driver and skip having to setup the interface on every
activation.
Adding SIM PIN caching feature to oFono. oFono now caches the SIM PIN1
type against the ICCID throughout its lifetime in a link list and
enters implicitly upon modem reset/crash.
Note, that this behavior can violate 3GPP spec 21.111, section 5.3 -
User Data stored in ME if that section is interpreted very strictly.
However, our interpretation is that firmware resets are allowed, based
on historic precedent. Helps in user experience by not barring out
cellular services unless pin is entered manually.
Handles cases of incorrect pin and sim pin changed externally.
Clear cached PIN incase modem disabled manually and selectively when
sim is removed.
Seperate 'pin_cache_enter_cb' added without dbus calls to handle
implict entering of cached pin.
For now this behavior is applicable to all modems by default. In the
future it may be needed to make this behavior opt in or otherwise
configurable.
After the convertion to l_uintset, the creation of new contexts fails
due to a range error being returned from l_uintset_find_unused().
The error happens because the uinset is created with a min-value of 1,
but the start-value passed to l_uintset_find_unused() is initialized as
0.

Switch various conversions from GSM/UCS2 to UTF8 from glib based
implementation over to ell.
This also converts all related g_free calls to l_free calls (though in
the end they are equivalent calls to free)
this patch provides the handling for the modem-depending powered timeout
It provides the trivial implementation for
ofono_modem_set_powered_timeout_hint, introducing the ofono_modem
variable timeout_hint, used together with the existing ofono_modem
variable timeout.
The default value, previously hardcoded as a magic number, is provided
by the DEFAULT_POWERED_TIMEOUT define and set as soon as the
ofono_modem struct is created, and then can be overwritten by the
aforementioned ofono_modem_set_powered_timeout_hint.
Many LTE networks require user authentication, even for the default
context. In particular, most of the private APNs use this facility
to add some control on top of the MNO providing the service, so that
another user of the same network cannot access the private one.
As such, we add these parameters to the default context
settings that will attempt to use when registering to the network.
The additional parameters added by this patch are: protocol, user, and
password. These are sufficient to allow to connect to networks
available to the patch author where ofono previously failed to register
to the network at all.

There are a large number of files in the tree that define _GNU_SOURCE
despite not actually using features hidden behind this flag. This patch
removes all these definitions in one fell swoop...
the following functions:
gprs_proto_to_string
gprs_proto_from_string
gprs_auth_method_to_string
gprs_auth_method_from_string
are moved from gprs.c to common.c, with related declaration in common.h
so that they can also be accessed from lte core functions
Patch to be considered, if support for EUTRAN SMS states accepted.
SMS registered flag while sending sms to consider the new EUTRAN
registered status also.
Plugins may reference data structures allocated by each other.
They all need to be deinitialized first, only then it should be
safe to unload the libraries.
In case we try to enter the PIN/PUK and fail to enter a correct code,
the PIN/PUK retries are not rechecked as they should be.

Typically responses to USSD requests are coming with status
zero (NOTIFY) but some are coming with status 2 (TERMINATED).
If those contain data, the data should be presented to the user.
If an operation is in progress and an operation is canceled, we don't
actually destroy it, but simply clear out the callback. In the case of
a context being destroyed, the operation is left on the simfs op_q with
a dangling pointer to the already freed context. So the current logic
in sim_fs_op_free tries to access invalid memory.
Fix this by performing the watch operations in sim_fs_end_current
instead and setting the context pointer appropriately.

Calling from memory index is very similar in functionality to dialing
the last called number. So we rename the functions so we can reuse them,
to deal with memory index calling. Function names now also reflect this
is for hfp.
In addition to not doing unnecessary SIM I/O, this fixes memory leaks
like this one:

This is normally a bug in some application using the D-Bus library.
Some protocols (like MBIM) do not properly support default bearer
semantics. Instead they want everything to function like UMTS/GSM where
the context has to be explicitly attached / activated.
This change is likely to break multiple drivers. One can easily emulate
the current behavior (pre-this commit) by calling
ofono_sim_initialized_notify after ofono_sim_inserted_notify.
All the functionality for the simauth driver was moved
into the sim atom. This patch transitions the simauth
atom to using those API's instead of the simauth driver
API's.
With this change it made more sense to store each AID
as its own object structure so the AID and object path
could be re-used rather than generating it on the fly.
Renamed the simauth 'sim' variable to 'sa' to keep it
consistent now that the simauth structure references
the sim atom as 'sim'.
API to create a sim context for the ISIM application, if found.
During AID discovery, if an ISIM AID is found, a new fs object is
initialized for the ISIM which will be used for any future
ISIM context creation.
