This patch adds a 'mtu' value to the Ip4Config and Ip6Config property of
a Bearer object, which indicates the value of the maximum transmission
unit for the established connection when such information is available
(e.g. via QMI_WDS_GET_RUNTIME_SETTINGS on a QMI modem or
MBIM_CID_IP_CONFIGURATION on a MBIM modem).
ensure_internal_ports() didn't deep-copy the ports array, which
meant that anything calling mm_modem_port_info_array_free() was
freeing the internal memory owned by MMModem if it retrieved
the array with mm_modem_get_ports().

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.
We want to expose in the Modem interface the list of supported IP families, and
the easiest way to do so is to have the IP family as flags, and provide in the
interface a single enum.
Also, a value of 0 for a MMBearerIpFamily specifies that no flags are set, so
just rename it to 'NONE'.
And add a new 'ANY' value which sets all flags to 1.
We cannot g_array_unref() the GArray when get()-ing bands as that will clear
the contents of the GArray, even if there are references around. Instead, just
dup the array contents when returning.
