In the case a unsolicited indication for UREG was received
while the status was polled. The poll response failed to parse.
This since the unsolicited indication only carries one
parameter, while the poll response is expected to carry two.
Update the code to loop until the response is found.
The log below shows a case where this happened.

It turns out that both L2xx and L4xx modems are a bit
buggy when it comes to send CREG URC's when the tech changes.
Try to overcome this by subscribing to both UREG and CREG,
and poll the other when any of the URC's are received.
Protect from doing simultaneous polls though.
In case a context get deactivated when a AT+CGACT=0 is
not issued, indicate that to gprs core.
This can happen if the device has an auto activated
LTE context and modem switches over to for instance UTRAN.
For uBlox modems, a bit of custom setup is required, but after that the
generic "atmodem" (27.007-compatible) method implementations are
sufficient. This driver, therefore, just puts the custom probe method
into place and defers remaining functionality to the recently exported
atmodem implementations.
Fixes:

The ublox modems always run DHCP when in router mode.
Unfortunately the code overwrote the IP settings with
static IP settings while activating.
Now we respect the networking_mode regardless if
we read settings during activation or read settings
phase.
The TOBY L2 may run in either "bridge" mode or "router" mode. For this
model, query the configured mode so that the appropriate settings are
communicated when the context is activated.
The TOBY L4 supports only "router mode" where the modem presents a
network interface that one can run a DHCP client against. Behind this
interface, the modem takes care of routing packets via NAT by:
i) selecting the relevant context based on destination IP
ii) using the first activated context as the default route
In order to have the connection manager, thus, do the right thing, the
context only needs to report itself as being active and with the IP
settings set to method "dhcp". There's no need for the connection manager
to know details like what IP address the context was assigned.
Tested with connman that does the right thing when it finds an active
"dhcp" context.
There are a couple of semi-independent changes here:
* use the 'vendor' parameter to pass the modem 'model'
* support TOBY L4 modem which uses a fixed CID for configuring the EPS
default bearer
* add the setup of authentication parameters that was recently added to
the atmodem LTE driver
This flag should be set on devices that support multiple USB profiles
and will be used to determine whether or not querying USB profiles is
appropriate/necessary.
This sets up some device model data structures and adds some helpers for
manipulating them. These data structures are a first step to trying to
support the large number of devices that ublox produces with a common
driver structure.
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 driver vtables are read-only structures. This patch declares them as
'const' allowing the compiler to (optionally) put them in the RELRO
section. RELRO pages may be marked as read-only by the linker after
the relocations have been done ensuring that they aren't inadvertently
or maliciously altered at runtime.
Added the explicit support for auth NONE.
It needs to be added in all drivers/*/gprs-context.c atoms.
This method is already supported by all atoms that support
authentication (ie, all but Sierra' swmodem driver).
The behavior is left unchanged in case of inconsistent parameters:
if username is empty, then fallback to auth NONE.

drivers/ubloxmodem/netmon.c: In function ‘req_cb_data_unref’:
drivers/ubloxmodem/netmon.c:131:10: error: ‘return’ with a value, in
function returning void [-Werror]
return NULL;
This adds a netmon driver for ublox. The driver support both +COPS and
+CESQ commands to return the previously added ofono netmon types:
RSCP: Received Signal Code Power
ECN0: Received Energy Ratio
RSRQ: Reference Signal Received Quality
RSRP: Reference Signal Received Power
Current revision makes the driver use ref countig when chaining multiple
AT commands.
The U-Blox documentation specifies the following:
* get interface ip and dns from +CGDCONTRDP
* get gw ip and netmask from +UIPADDR
However, different firmware versions have different befaviour:
* On newer firmware, +UIPADDR returns error. But it's possible to configure
gateway ip == ipterface ip (read from CGDCONTRDP).
* On older firmware, we can actually use the commands specified in the
docs.
This patch runs +CGDCONTRDP, configures everything and then tries to run
+UIPADDR. In that works, reconfigures gw ip and netmask.
Adds U-Blox Toby L2 driver for setting the default APN via the
+UCGDFLT command. Currently only IPv4 is supported. APN is
not stored to modem's non-volatile memory. oFono will manage this
default APN via it's config storage.
When receiving an empty default APN, the value is reset.
For now the driver works only with bridged mode for 2G/3G.
Once it activates the context it reads the ip, netmask,
gw, dns and sets them in the context settings.
