Until now the internal DHCP client could start a DHCPv6 transaction
but was not able to parse the lease and pass the information back to
the core. Add the missing glue code to make this work.

Choose a new logging format.
- the logging format must not be configurable and it must be the
same for all backends. It is neat that journal supports additional
fields, but an average user still posts the output of plain
journalctl, without "--output verbose" (which would also be hard
to read).
Also, we get used to a certain logging format, so having different
formats is confusing. If one format is better then another, it should
be used for all backends: syslog, journal and debug.
The only question is, what is the best format.
- the timestamp: I find it useful to see how much time between two
events passed. The timestamp printed by syslog doesn't have sufficient
granularity, and the internal journal fields are not readily available.
We used to print the timestamps for <error>, <debug> and <trace>,
but ommited them for <info> and <warn> levels. We now print them for
all levels, which has a uniform alignment.
- the location: the "[file:line] func():" part is mostly redundant
and results in wide lines. It also causes a misalignment of the
logging lines, or -- as I recently added alignment of the location --
it results in awkward whitespace and truncation.
But the location is really just necessary because our logging messages
are bad:
"<debug> [1456397604.038226] (9) 11-dhclient succeeded"
The solution to this is not
"<debug> [1456397604.038226] [nm-dispatcher.c:358] dispatcher_results_process(): (9) 11-dhclient succeeded"
but a properly worded message:
"<debug> [1456397604.038226] dispatcher: request #9, script 11-dhclient succeeded"
- logging-message: we need to write better logging messages.
I like some form of "tags" that are easy to grep:
"platform: signal: link changed: 4: ..."
Downside is, that this is not nice to read as a full sentence.
So, especially for <info> and <warn> logging, more human readable
messages are better.
We should find a compromise, where the log message explains what
happens, but is still concise and contains patterns that are easy
to grep and identify visually.

Some drivers (or things outside NM like 'powertop') may turn powersave
on, so don't touch it unless explicitly configured by user.
To achieve this, add new 'default' and 'ignore' options; the former
can be used to fall back to a globally configured setting, while the
latter tells NM not to touch the current setting.
When 'default' is specified, a missing global default configuration is
equivalent to 'ignore'.
It is possible to enable Wi-Fi power saving for all connections by
dropping a file in /etc/NetworkManager/conf.d with the following
content:
[connection]
wifi.powersave=3

Only install nm-settings-ifcfg-rh.5 man page if the ifcfg-rh
configuration plugin has been enabled.
But still add them to EXTRA_DIST so that the source tarball
contains the generated man-file, but it isn't installed.

- it controls echoing passwords input on terminal
- it replaces --show-secrets in 'nmcli connection show', which is deprecated now
- it replaces --show-password in 'nmcli device wifi hotspot', which is deprecated now
If the supplicant supports it and the connection requests it, tell
the supplicant to randomize the MAC address for the association.
In addition, like both iOS, Android, and other OSs always randomize
the MAC address when performing a WiFi scan.
Synopsis:
nmcli connection clone [--temporary] [id|uuid|path] <ID> <new name>
It copies the <ID> connection as <new name>. The command is very useful
if there is a connection, but another one is needed for a related
configuration. One can copy the existing profile and modify it for the
new situation.
For example:
$ nmcli con clone main-eth second-eth
$ nmcli con modify second-eth connection.interface-name em4

The list of LLDP neighbors is available through the D-Bus interface
and libnm already provides functions to retrieve it; make the list
available through nmcli as well. Sample output:
$ nmcli device lldp

NEIGHBOR[0].PORT-ID: 1

It is useful to show nmcli-generated hotspot password (if a user does not
provide his own password). Without the option the user would have to look into
the generated profile in order to find out the password.
Add the 'lldp' property to NMSettingConnection, which specifies
whether the reception and parsing of LLDP frames to discover neighbor
devices should be enabled.
No longer support disabling the global-dns configuration via the
"enable" option.
Instead, the user can put the entire dns-configuration in one separate
snippet, and disable it altogether with ".config.enable".
Support a new configuration option
[.config]
enable=<ENABLED>
for configuration snippets.
This new [.config] section is only relevant within the snippet itself
and it is not merged into the combined configuration.
Currently only the "enable" key is supported. If the "enable" key is
missing, it obviously defaults to being enabled. It allows snippets
to be skipped from loading. The main configuration "NetworkManager.conf"
cannot be skipped.
<ENABLED> can be a boolean value (false), to skip a configuration
snippet from loading.
It can also be a string to match against the NetworkManager version,
like "enable=nm-version-min:1.1,nm-version-min:1.0.6"
There are several motivations for this:
- the user can disable an entire configuration snippet by toggeling
one entry.
This generalizes the functionality of the global-dns.enable
setting, but in a way that applies to configuration on a per-file
basis.
- for developing, we often switch between different versions of
NetworkManager. Thus, we might want to use different configuration.
E.g. before global-dns options, I want to use "dns=none" and manage
resolv.conf myself. Now, I can use global-dns setting to do that.
That can be achieved with something like the following (not exactly,
it's an example only):
[.config]
enable=nm-version-min:1.1
[main]
dns=default
[global-dns-domain-*]
nameserver=127.0.0.1
Arguably, this would be more awesome, if we would bump our micro devel
version (1.1.0) more often while developing 1.2.0 (*hint*).
- in principle, packages could drop configuration snippets and enable
them based on the NetworkManager version.
- with the "env:" spec, you can enable/disable snippets by configuring
an environment variable. Again, useful for testing and developing.
