This ensures that the next time secrets are required, they will
be requested from the settings service. Internally, NM shouldn't
be caching secrets; it should always request them from the settings
service so that the settings service can enforce policy about
password lifetime, if it wants to.
Option '--multiline' was replaced with '--mode tabular|multiline'.
It was neccessary to be able to switch to tabular output mode for
'dev list' and 'con list id|uuid' commands as they now print out
in multiline mode by default. All other commands are in tabular
mode by default.
The original OLPC mesh patch confused g_source_remove() with
g_signal_handler_disconnect(), so the signal handler that the
mesh device creates for the managers 'device-added' signal was
getting called after that mesh device instance was freed, which
is of course bad.
nmcli uses its own code to dump connections' details instead of
libnm-util's nm_connection_dump(). It allows to structure output
and present values of the settings according to nmcli needs.
After the DUN branch merge (I think?) a number of NM_IS_MODEM
calls were left around which now always return FALSE since
NMDeviceCdma and NMDeviceGsm aren't subclasses of NMModem anymore.
But we still need generic "is this a modem subclass" checks in
a few places, so add a modem base class that both the GSM and
CDMA device classes inherit from and use that.
Plus, we want to consolidate a ton of the common code in
nm-device-gsm.c and nm-device-cdma.c into the base class in the
future anyway.
If SSID is a UTF-8 string, it is printed as it is, but enclosed in quotes.
Otherwise the bytes are converted to hex string (in uppercase).
The added quotes for UTF-8 string allow to disambiguate the two forms.
Modifications are mainly for multiline mode to ease parsing - each
field name is prefixed with a section name.
'dev list' now also supports printing particular sections specifed via
'--fields' option.
