Previously, DHCP was used. According to MBIM Specification v1.0 errata 1 [1],
section 10.5.20, MBIM_CID_IP_CONFIGURATION,
if MBIM information element containing IP configuration is available,
host shall use it, and fall back to in-band mechanisms to acquire it therwise -
therefore make static configuration the default.

Current implementation needlessly creates both IPv4 and IPv6
sub-interfaces for single-stack IP types. Limit this only to selected IP
type. While at that, ensure that IP type is also passed to umbim during
"connect" phase. In addition, detect the actual established connection
type returned by umbim and set up subinterfaces according to that,
not to requested configuration. While at that, allow empty IP type explicitly,
interpreted as "any" according to MBIM specification.

Subsequent calls to 'umbim connect' do not have any effect if a failure
occured, and in such case an infinite loop without timeout is created,
leading to possibility of interface stuck at connecting forever.
Drop this loop, and issue MBIM disconnect properly, so netifd can
restart from scratch.
This issue can be observed with Sierra EM7455 at changing APN, which
causes network re-registration by default, and a MBIM transaction
timeout, which is resolved on next interface bringup by netifd.

Previous implementation automatically set up connections for both IPv4
and IPv6, even if one of them isn't supported. Respect the "pdptype"
option in the same way, as it is done for QMI or NCM, and only start the
respective PDN sessions, if set.

There are mbim compatible wwan modules available which do not support
the dhcp autoconfiguration. (e.g. gemalto Cinterion ELS81)
This adds the possibility to get the configuration parameters from mbim.

Allow registration if the SIM is roaming or partner mode, by adding two
new options to the protocol.
Until now, such registration failed because umbim returns exit codes 4 and
5 for such situations.

Otherwise, connection setup may fail due to JSON parse error in netifd.

PIN2 is used only to restrict changing of fixed dialling feature,
does not affect network registration. Therefore explicitly check for
PIN1 state during connection setup, which is required for network
registration.

This is needed to properly close the control channel.
Otherwise, on the next try the caps call may fail.
