This commit enables a new core ModemManager daemon option, so that automatic
detection of available modems is totally disabled: '--no-auto-scan'. Note that
this option also replaces the previously used '--test-no-auto-scan' option,
which was only used during tests.
Along with the new ModemManager option, a new ReportKernelEvent() method in
the API is defined, which allows notifying the daemon of which interfaces it
should be accessing, as well as the main details of each interface. The only
mandatory parameters in the new method are 'action' (add/remove), 'name' (the
name of the interface) and 'subsystem' (the subsystem of the interface).
The mmcli tool has support for using the new api method via several new options:
* The '--report-kernel-event' option allows specifying device ports one by
one, and is a direct mapping of the ReportKernelEvent() method:
$ sudo mmcli --report-kernel-event="action=add,name=wwan0,subsystem=net"
$ sudo mmcli --report-kernel-event="action=add,name=cdc-wdm0,subsystem=usbmisc"
* The '--report-kernel-event-auto-scan' option uses udev monitoring to notify
events automatically to the daemon. This allows to operate in a way
equivalent to the default daemon operation (with implicit auto-scan).
Worth noting that the ReportKernelEvent() method is only usable when
'--no-auto-scan' is explicitly used in the daemon. An error will be reported if
the method is tried while standard udev monitoring is enabled (implicit if
auto scan isn't explicitly disabled in the daemon).
If mmcli is going to be used only to report 'real time' events, an optional
'--initial-kernel-events=[PATH]' may be given in the ModemManager call to
automatically process a set of port kernel events one by one on boot. The file
may e.g. contain:
action=add,name=wwan0,subsystem=net
action=add,name=cdc-wdm0,subsystem=usbmisc
The default setup uses a refresh time of 30s, which means that even if the GPS
location updates are received at a higher frequency, the DBus interface will
still expose at most one update every 30s.
This patch includes a new "SetGpsRefreshTime()" method in the Location
interface, which takes a single 'u' parameter, specifying the refresh rate to
use, in seconds. This method also allows 0 being passed, which will make the
implementation to publish the GPS location updates are soon as ModemManager
detects them.
Along with the new method, a "GpsRefreshTime" read-only property is exposed
to specify the refresh time in effect.
The new method and property will only be applicable if the device has GPS
capabilities.

We will expose a new 'Ports' property listing all ports currently known by a
given modem. Ports which are not used but are detected as being part of the
modem will be listed with an 'unknown' port type.
This change uses the new 'MMModemPortType' enum and the new 'MMModemPortInfo'
helper struct to handle these values in libmm-glib. The already available
'MMPortType' enum hasn't been re-used for the interface because it contains
values that we don't need (e.g. IGNORED).
The port list is now also included in the modem information command of mmcli:
$ sudo mmcli -m 0
/org/freedesktop/ModemManager1/Modem/0 (device id '97b7b99e3e2bea103880545b619fb05a3cc81b26')
-------------------------
System | device: '/sys/devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.4'
| drivers: 'qcserial, qmi_wwan'
| plugin: 'Gobi'
| primary port: 'cdc-wdm0'
| ports: 'ttyUSB0 (qcdm), ttyUSB1 (at), cdc-wdm0 (qmi), wwp0s29u1u4 (net)'

We won't allow changing modes or bands through Simple.Connect(). Applications
should instead look at the corresponding SupportedBands or SupportedModes, and
then use SetCurrentBands() or SetCurrentModes() explicitly.
And also make it a list of masks, specifying which are the specific combinations
supported, not just one mask with all.
E.g.:
-------------------------
Hardware | manufacturer: 'Sierra Wireless, Incorporated'
| model: 'MC7710'
| revision: 'SWI9200X_03.05.19.04ap r5475 carmd-en-10527 2012/09/17 17:57:14'
| supported: 'gsm-umts
| gsm-umts, lte'
| current: 'gsm-umts, lte'
| equipment id: '358178040668164'
We now have a single 'CurrentModes' property which contains both values in a
tuple with signature "(uu)".
Also, rename 'SetAllowedModes()' to 'SetCurrentModes()', and update the list of
arguments expected to have a single "(uu)" tuple.
