Some of the AT-based connection methods don't have any way to query
connection status, or we don't have a proper implementation for those
yet. Ignore the reload operation in all those.
Both the Simple.Connect() and Modem.CreateBearer() are updated to
allow a new 'multiplex' setting in the properties provided by the user
in both of these methods.
The new setting expects a MMBearerMultiplexSupport enum indicating
what kind of multiplex needs the user has:
* none: if multiplex must not be used.
* requested: if multiplex should be used if available.
* required: if multiplex must be used.
The underlying implementations will take care of accepting or
rejecting the setting depending on the system and modem capabilities.
Each different plugin or protocol had a different connection attempt
value. E.g. QMI and MBIM both used 60s max for the connection attempt,
while the u-blox plugin had up to 180s for ECM based connection
setups.
This commit consolidates all plugins and protocols to use the same
timeout values for commands that may take long to respond, e.g. a
connection atempt under low signal quality conditions.
A value of 180s for the connection attempt steps and 120s for a
disconnection attempt step is considered. Note, though, that in some
cases (like a IPv4v6 setup attempt using QMI) we may have more than
one such long step, so this doesn't mean that a connection attempt
will always take less than 180s.
Users of the connection/disconnection APIs should be able to handle
the case where the attempt times out in their side (e.g. with a lower
DBus request timeout), and which would not mean the actual request
they did really failed. E.g. a connection attempt with a DBus timeout
of 30s may fail in the user with a timeout error, but the attempt
would still go on for as much as the plugin/protocol needs.

A default implementation to monitor the ongoing connection is provided in the
generic MMBroadbandModem, based on AT+CGACT? to check whether the PDP context
of the connection (identified by the cached cid) is active or not.
This commit also disables the connection monitoring logic in those plugins that
have custom connection methods.
The generic disconnection logic now already handles getting the port fully
closed and a wait time before reopening it, so no need for a custom
disconnection logic any more.
Instead of returning 3 variables in connect_finish(), return a single reference
counted struct. This simplifies how the result is built and passed within a
GSimpleAsyncResult to each _finish() method.
This also simplifies the dialling step in the 3GPP connection sequence, as we
can use the same new type.
Both the ModemManager daemon and the mmcli will now include `libmm-glib.h' only.
We also handle two new special `_LIBMM_INSIDE_MM' and `LIBMM_INSIDE_MMCLI'
symbols, which if included before the `libmm-glib.h' library allow us to:
* Don't include the libmm-glib high level API in the ModemManager daemon, as
the object names would clash with those in the core.
* Define some of the methods of helper objects to be included only if compiling
ModemManager daemon or the mmcli.
The base MMBearer object will receive the MMBearerProperties configuration,
which contains every generic and plugin-specific set up. Not every configuration
parameter will be used by every implementation (e.g. not every bearer needs
user/password).
The Bearer object will expose every configuration parameter received in its
`Properties' property in the interface, even if it's not really used.
Instead of the `_in_port()' variants, we'll provide more generic
`_full()' methods. These should be used either if we want to send commands
to a specific port, or if we want to use a specific user-provided GCancellable.
In addition to this user-provided GCancellable, we keep the internal modem-wide
one.
* mm_base_modem_peek_port_* () will return either a port object (no new
reference), or NULL if none available.
You would usually peek() a port if you're going to use it just in the current
method, as there is no way to that reference to get invalid (we're single
threaded).
* mm_base_modem_get_port_* () will return either NEW references to valid
port objects, or NULL if none available.
And, you would usually get() a port, whenever you want the port object to be
valid even out of the current method, for example when keeping it in the
context of an async operation.
Also, we need to consider that the primary AT port MAY BE NULL when you
peek() or get() it. This is due to the fact that we may be releasing ports
(due to device disconnection) in the middle of async operations.
Renamed `MMCommonBearerProperties' to `MMBearerProperties', and removed the
`MMBearerProperties' provided in libmm-glib. We'll just use the original one
from libmm-common always.
Renamed `MMCommonBearerIpConfig' to `MMBearerIpConfig', and removed the
`MMBearerIpConfig' provided in libmm-glib. We'll just use the original one
from libmm-common always.
