To support the widest variety of modems, allow restoring previous
behaviour of configuring the link throug means of DHCP(v6) exclusively.
Change the default value of "dhcp" and "dhcpv6" UCI options to "auto",
while keeping the default behaviour of "prefer out-of-band configuration",
intact. Setting "dhcp" or "dhcpv6" to boolean 1 will now force using
DHCP and DHCPv6, respectively.

Previously, DHCP was used. According to MBIM Specification v1.0 errata 1 [1],

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.

The Mikrotik R11e-LTE6 modem is similar to ZTE MF286R modem, added
earlier: it has a Marvel chip, able to work in ACM+RNDIS mode, knows ZTE
specific commands, runs OpenWrt Barrier Breaker fork.
While the modem is able to offer IPv6 address, the RNDIS setup is unable
to complete if there is an IPv6 adress.
While it works in ACM+RNDIS mode, the user experience isn't as good as
with "proto 3g": the modem happily serves a local IP (192.168.1.xxx)
without internet access. Of course, if the modem has enough time
(for example at the second dialup), it will serve a public IP.
Modifing the DHCP Lease (to a short interval before connect and back to
default while finalizing) is a workaround to get a public IP at the
first try.
A safe workaround for this is to excercise an offline script of the
pingcheck program: simply restart (ifdown - ifup) the connection.
Another pitfall is that the modem writes a few messages at startup,
which confuses the manufacturer detection algorithm and got disabled.

To send this AT command to the modem the "runcommand.gcom" script
dependency is moved from comgt-ncm to comgt.
As the comgt-ncm package depends on comgt already, this change
is a NOOP from that point of view.
But from the modem's point it is a low hanging fruit as the modem
is usable with installing comgt and kmod-usb-ncm packages.

This patch solves the problem of receiving "error" responses when
initially calling gcom. This avoids unnecessary NO_DEVICE failures.
A retry loop retries the call after an "error" response within the
specified delay. A successful response will continue with the connection
immediately without waiting for max specified delay, bringing the
interface up sooner.

This reduces open coding and allows to easily add a knob to enable
it treewide, where chosen packages can still opt-out via "no-lto".
Some packages used LTO, but not the linker plugin. This unifies 'em
all to attempt to produce better code.
Quoting man gcc(1):
"This improves the quality of optimization by exposing more code to the
link-time optimizer."
Also use -flto=auto instead of -flto=jobserver, as it's not guaranteed
that every buildsystem uses +$(MAKE) correctly.

Note: libnl, mbedtls and opkg only used the CFLAGS part without the
LDFLAGS counterpart. That doesn't help at all if the goal is to produce
smaller binaries. I consider that an accident, and this fixes it.
Note: there are also packages using only the LDFLAGS part. I didn't
