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.

7880de8 uqmi: sync data from libqmi project
d647f8d uqmi: add more diagnostics commands
6f95626 uim: add --uim-get-sim-state
Use newly introduce --uim-get-sim-state command to query PIN status
from modems which require using uim instead of dms command for that.

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.

Give possibility to wait forever the registration by setting timeout
option to 0.
No timeout can be useful if the interface starts whereas no network is
available, because at the end of timeout the interface will be stopped
and never restarted.
