The current implementation only checked if uqmi itself executed
correctly which is also the case when the returned value is actually
an error.
Rework this, checking that CID is a numeric value, which can only
be true if uqmi itself also executed correctly.

uqmi contains a command for directly querying the modem if there
is a valid data connection, so let's use it.
This avoids the cases were all previous tests are succesful, but the
actual data link is not up for some reasons, leading to states were we
thought the link was up when it actually wasn't ..

Originally, the implementation only checked if uqmi command
execution succeeded properly without actually checking it's returned data.
This lead to a pass, even when the returned data was indicating an error.
Rework the verification to actually check the returned data,
which can only be correct if the uqmi command itself also executed correctly.
On command execution success, value "pdh_" is a pure numeric value.

If a device only supports the 2nd verification method (uim),
the first method will fail as expected reporting an error:
"Command not supported"
Silence both separate methods and only report an error regarding
pin verification if both fail.

Some newer LTE modems, like the MC7455 or EC25-E do not support
"802.3" mode, and will stay in "raw-ip" regardless of the mode being
set.
In this case, the driver must be informed that it should handle all
packets in raw mode. [1]
This commit fixes connectivity issues for these devices.

If you unplug a QMI device, the /dev/cdc-wdmX device
disappears but uqmi will continue to poll it endlessly.
Then, when you plug it back, you have 2 uqmi processes,
and that's bad, because 2 processes talking QMI to the
same device [and the same time] doesn't seem to work well.

Update uqmi to latest version, which brings about support for
specifying a call profile index instead of APN. A specific index
different from 1 must be used for some service provider and modem
combinations.
Also change option dhcp to dhcpv6, since IPv4 now always uses DHCP,
replace option ipv6 with pdptype, which is less ambiguous, and
make autoconnect optional and default it to off for IPv6 due to it
not working with statically configured IPv6.

Commit 8f24ee6382 ("uqmi: Add proper IPv6 support") changed the code
to fetch the IPv4 address via QMI by default instead of using DHCP to
make it consistent with the IPv6 codepath.
This breaks on at least some Sierra Wireless cards, where data exchanges
fail to work until the host has fetched a DHCP lease.
Leave v6 as it is, but always use DHCP for v4.

Use the new --ip-family option to start both IPv4 and IPv6 sessions
by default. Autoconnect can't be used when starting two sessions,
so revert back to using the client IDs and packet data handles for
handling the network connection.
Some modem firmwares do not implement a RA server, therefore by
default use outband IP configuration and static addressing. Some
other firmwares report bogus IP configuration with the WDS get
current settings command. In this case inband configuration with
DHCP/RA can be optionally enabled by setting option dhcp to 1.
Per 3GPP standard a /64 prefix is served to all clients, which is
extended to LAN as specified in RFC 7278.

Instead of connecting once and saving the packet data handle, let the
firmware handle connecting/reconnecting automatically. This is more
reliable and reduces reliance on potentially stale data.
Use the global packet data handle to attempt to disable autoconnect
before restarting the connection. This ensures that the firmware will
take the new APN/auth settings.

Many of the 4G/LTE and 3G modems utilize the QMI-protocol to control the
modem. At the moment there is no support for them in OpenWrt. This
patch adds support for them in the form of a netifd script and a
control utility. Tested with Huawei E398 and ZTE MF820D (which requires
a delay of ~30 s before responding to QMI commands). I put myself up as
the maintainer, feel free to change this if you desire.
