Evaluating the return value of 'json_load' didn't work in the
intended way resulting in PIN status no longer being read on modems
where --get-pin-status doesn't fail.
Fix this by trying --get-pin-status first and checking if pin1_status
field exists in JSON, and if it doesn't try again with
--uim-get-sim-state.
Fixes: #9501

Modems used in ZTE mobile broadband routers require to query the data
session status using the same CID as one used to establish the session,
otherwise they will report the session as "disconnected" despite
reporting correct PDH in previous step. Without this change, IPv6
connection on these modems doesn't establish properly. In IPv4 this bug
is present as well, but for some reason querying of IPv4 status works
using temporary CID, this however seems noncompliant with QMI
specifications, so fix it as well.

Setting the plmn to '0' (auto) will implicitly lead to a (delayed)
network re-registration, which could further lead to some timing
related issues in the qmi proto handler.
On the other hand, if you switch back from manual plmn selection
to auto mode you have to set it to '0', because this setting is
permanently "saved" in the wwan module.
Conclusion:
If plmn is configured, check if it's already set euqally in the module.
If so, do nothing. Otherwise set it.

There already was an option for autoconfiguring IPv4 from QMI but this
was removed by commit 3b9b963e6e ("uqmi: always use DHCP for IPv4").
DHCP does not work on MR400 LTE module (in TL-MR6400 v4) so let's readd
support for IPv4 autoconf from QMI but this time allow to configure this
for IPv4 and IPv6 independently and keep DHCP default on IPv4.

The following uqmi "pin1_status" values are evaluated:
- disabled
Do not verify PIN because SIM verification is disabled on this SIM
- blocked
Stop qmi_setup because SIM is locked and a PUK is required
- not_verified
SIM is not yet verified. Do a uqmi --verify-pin1 command if a SIM is
specified

The control device /dev/cdc-wdm0 is not available immediately on the
D-Link DWR-921 Rev.C3, therefore the wwan interface fails to start at
boot with a "The specified control device does not exist" error.
This patch alters /lib/netifd/proto/qmi.sh to wait for
network.wwan.delay earlier, before checking for the control device,
instead of just before interacting with the modem.
One still has to use network.wwan.proto='qmi', as the "wwan" proto
performs that sort of check before any delay is possible, failing with a
"No valid device was found" error.

uqmi contains a command for directly querying the modem if there
is a valid data connection, so let's use it.

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.

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]

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,
