We must send ATZ alone and once reply received, wait some time before sending
the next initialization commands. Otherwise, the next commands will receive
garbage as reply. The only way to handle this is to override the whole generic
initialization phase.
Make port roles more flexible. We have modems that do PPP
on interfaces other than the primary interface, and that
wasn't possible with the old code. So clean up all that
logic and move the port organization code into the core
so we can reduce code in the plugins.
In the new world order, the plugins say whether the port
is a QCDM port, an AT port, or ignored. If it's an AT
port the plugins get to tag it as primary, secondary, or
PPP, or any combination of the 3. This allows for modems
where PPP should really be done on the secondary port
(Huawei E220, Sierra devices) so that the primary port
stays open for command and status.
After all ports are grabbed by the generic classes, they get
"organized", which assigns various ports to the roles of
PRIMARY, SECONDARY, DATA, and QCDM based on specific rules
and hints that the plugin provided (which are expressed as
MMAtPortFlags).
The plugin code is responsible for determining the port
hints (ie MMAtPortFlags) at probe time, instead of having
a combination of the plugin and the modem class do the
job. This simplifies things greatly for the plugins at
the expense of more complicated logic in the core.
This is the port of commit 96505d42ed62327101dcee7c2bf31177b0bb1c9f
to the 06-api branch.
Split the after power up step into:
* querying supported functionality status during the first power-down request.
* querying supported networks during supported modes loading.
Need to suggest that it's QCDM since the MMPortProbe stuff
doesn't get passed through to mm_base_modem_grab_port() so
we can't detect QCDM ports automatically there.
We chain up the Generic plugin created MMBroadbandModem objects within the
GDBusObjectManagerServer in MMManager, so that they get properly exported in
DBus.
Also removed the MMSerialError implementation from `src/mm-errors.[h|c]', as it
is now included in the new `include/ModemManager-errors.h' header file. All the
other enums and errors without clashing names will be ported afterwards to the
new base code.

Modem subclasses no longer get asked to handle port grabbing
themselves. Instead, that's now done by the generic classes
(MMGenericCdma and MMGenericGsm) and the plugins are notified
when a port is grabbed so they can add unsolicited response
handlers for it. After all ports are grabbed by the generic
classes, they get "organized", which assigns various ports
to the roles of PRIMARY, SECONDARY, DATA, and QCDM based
on specific rules and hints that the plugin provided (which
are expressed as MMAtPortFlags). The plugins then have
a chance to perform fixups on the primary port if they choose.

Seems that launching AT+CSQF when not registered ends up timing out. AT+CSQF
is meant to be the fast version to get the signal quality, and is expected to
return instantly with the last cached signal quality value. But if we never
got registered, there is no such cached value, so it probably waits to get the
first one.
