Implement the detailed signal info interface for some Huawei 3GPP modems
including those based on HiSilicon chipsets like the E3276. Known not to
work on many Qualcomm-based Huawei modems like E392, E397, and E367 as
they don't support the ^HCSQ command, but they do support QMI and so
have access to the extended signal interface via QMI.
For non-QMI/non-MBIM Huawei devices that use HiSense chipsets,
the recommended way to create the connection is to use NDISDUP
and either DHCP on the net interface, or the ^DHCP command.
There are some reports of devices that connect successfully, but
don't respond to DHCP requests on the interface. Try to get
IP addressing info from the device via ^DHCP and fall back to
telling clients to use actual DHCP if that fails.

Third revision of Huawei nwtime support. Takes on feedback from the
mailing list including helpers, some basic tests and use of the ^NTCT
command to determine network time support (^NWTIME). Expanded test cases,
more use of g_assert and more logical helper return values/errors.

Some Huawei modems (e.g. E220) may give an empty response for AT^SYSCFG=?, even
if they do support the command. Handle this case by prividing a default fallback
format string when this happens.
The original sysinfoex_parse() in MMBroadbandModemHuawei does not handle
unquoted <sysmode_name> and <submode_name> fields in ^SYSINFOEX responses,
which are sen on some Huawei modems (e.g. E303). This patch moves the
^SYSINFOEX parsing code to mm-modem-helpers-huawei.c, fixes the regex for
handling unquoted strings in ^SYSINFOEX responses, and adds unit tests.
The original sysinfo_parse() in MMBroadbandModemHuawei incorrectly sets
'out_sys_submode_valid' to TRUE even when <sys_submode> is not present
in a ^SYSINFO response. This patch moves the code to
mm-modem-helpers-huawei.c, fixes the regex for parsing ^SYSINFO
responses, and adds unit tests.
This patch changes MMBroadbandModemHuawei to use ^NDISSTAT unsolicited
messages to handle network-initiated disconnection. As a ^NDISSTAT
unsolicited message is similar to a ^NDISSTATQRY response, the patch
extends the ^NDISSTATQRY parser code to handle both ^NDISSTAT and
^NDISSTATQRY responses.
