As NMDevice now creates the NMPacrunnerManager instance
as needed, it is even more likely that the initial call
to nm_pacrunner_manager_send() will only queue (but not yet
send) the new config.
Later, when the D-Bus proxy is created, we will not get a
name-owner changed signal. We instead have to push the configuration
right away.
(cherry picked from commit 019b9fbfc0)
nm_pacrunner_manager_remove() required a "tag" argument. It was a
bug for callers trying to remove a configuration for a non-existing
tag.
That effectively means, the caller must keep track of whether a certain
"tag" is pending. The caller also must remember the tag -- a tag that he
must choose uniquely in the first place.
Turn that around and have nm_pacrunner_manager_send() return a (non
NULL) call-id. This call-id may later be used to remove the
configuration.
Apparently, previously the tracking of the "tag" was not always correct
and we hit the assertion in nm_pacrunner_manager_remove().

Usually, this "<allow send_destination="..."/>" part is shipped
by firewalld's D-Bus policy. However, if firewalld is initially
not installed with NetworkManager already running, dbus-daemon
seems to cache the missing permission for the D-Bus connection.
As a result, when installing and starting firewalld, NetworkManager
requests fail until restart:
firewall: [0x7f4b83643890,change:"eth1"]: complete: request failed (Rejected send message, 1 matched rules; type="method_call", sender=":1.3" (uid=0 pid=715 comm="/usr/sbin/NetworkManager --no-daemon ") interface="org.fedoraproject.FirewallD1.zone" member="changeZone" error name="(unset)" requested_reply="0" destination=":1.25" (uid=0 pid=1243 comm="/usr/bin/python -Es /usr/sbin/firewalld --nofork -"))

(cherry picked from commit cc1d409ba8)
We want to ignore certain errors from firewalld. In the past,
the error message contained only the error code.
Since recently ([1], [2]), the error message contains a longer text:
NetworkManager[647]: <debug> [1492768494.7475] device[0x7f7f21e78f50] (eth0): Activation: setting firewall zone 'default'

We now initialize the NMFirewallManager asynchronously. That means, at
first firewalld appears as "not running", for which we usually would
fake-success right away.
It would be complex for callers to wait for firewall-manager to be
ready. So instead, have the asynchronous requests be queued and
complete them once the D-Bus proxy is initialized.

Next we will get another mode, so an is-idle doesn't cut it.
It can be confusing where the mode is set and where it is only
accessed read-only. For that, add mode_mutable.
(cherry picked from commit 04f4e327a9)
Creating it asynchronously changes that on the first call to
nm_firewall_manager_get() the instance is not yet running.
Note that NMPolicy already connects to the "STARTED" signal and
reapplies the zones when firewalld appears. So, this delayed
change of the running state is handled mostly fine already.
One part is still missing, it's to queue add_or_change/remove calls
while the firewall manager is initializing. That follows next.

Cherry-picked commit from master which used the new
nmc->nmc_config member not available in nm-1-8.
We should use the nmc->show_secret member here.

Since commit 2d1b85f (th/assume-vs-unmanaged-bgo746440), we clearly
distinguish between two modes when encountering devices with external
IP configuration:
a) external devices. For those devices we generate a volatile in-memory
connection and pretend it's active. However, the device must not be
touched by NetworkManager in any way.
b) assume, seamless take over. Mostly for restart of NetworkManager,
we activate a connection gracefully without going through an down-up
cycle. After the device reaches activated state, the device is
considered fully managed. For this only an existing, non volatile
connection can be used.
Before 'th/assume-vs-unmanaged-bgo746440', the behaviors were not
clearly separated.
Since then, we only choose to assume a connection (b) when the state
file indicates a matching connection. Now, extend this to also assume
connections when:
- during first-start (not after a restart) when there is no
state file yet.
- and, if we have an existing, non volatile, connection which
matches the device's configuration.
This patch lets NetworkManager assume connection also on first start.
That is for example useful when handing over network configuration from
initrd.
This only applies to existing, permanent, matching(!) connections, so it is a
good guess that the user wants NM to take over this interface. This brings us
closer to the previous behavior before 'th/assume-vs-unmanaged-bgo746440'.

nm_config_device_state_*() always access the file system directly,
they don't cache data in NMConfig. Hence, they don't use the
@self argument.
Maybe those functions don't belong to nm-config.h, anyway. For lack
of a better place they are there.

'nmcli connection show <con_id1> --show-secrets'
secrets were not shown.
'nmcli connection show <con_id1> --show-secrets <con_id2>'
secrets were shown only for connection ids following the
"--show-secrets" option (so only for 'con_id2').
Fix these behaviors showing secrets for all connections also
if the "--show-secrets" option is put after the connection ids.
