This fixes the issue where all Ad-Hoc networks try to connect one after one on
NM startup instead of the managed network that has AP available.

Since commit 87a3df2e57, the unmanaged
flag NM_UNMANAGED_USER_SETTINGS could be overwritten via an explict
user decision (NM_UNMANAGED_USER_EXPLICIT).
It makes sense to allow user configuration from file to be changable
by an explict user action via D-Bus at runtime.
However, it also changes behavior for devices that are currently explicitly
managed. Previously, a reload of the NM_UNMANAGED_USER_SETTINGS would
immediately unmanaged the device:
- for keyfile: send SIGHUP to reload NetworkManager.conf
- for ifcfg-rh: `nmcli connection [re]load`
So this change in behavior could negatively affect users who rely
on being able to configure "NM_CONTROLLED=no" and expect to unmanaged
the device immediately. Thus revert the change.
Note that NM_UNMANAGED_USER_SETTINGS is anyway ugly and should be
deprecated:
- for keyfile, why having the option "keyfile.unmanaged-devices"
instead of a generic options?
- for ifcfg-rh, why put per-device configuration in a per-connection
file?
The preferred way is to configure NM_UNMANAGED_USER_UDEV via
"ENV{NM_UNMANAGED}". Maybe we should also add a new configuration
scheme via NetworkManager.conf.

The NM_UNMANAGED_USER_SETTINGS flags are determined by the settings plugins.
That is, either:
- keyfile's "unmanaged-devices" configuration option
- ifcfg-rh's "NM_CONTROLLED" option
- ifnet's "managed" option
Rename NM_UNMANAGED_USER_CONFIG to NM_UNMANAGED_USER_SETTINGS to reflect
that it this is user configuration determined by the settings plugin.
Change the logging format. For syslog, we will now always
print the timestamp (also for <info> and <warn> messages).
Also, when printing the file location, we will always
align it.
For journal logging, also enable the timestamp. While the timestamp
is already captured separately by journal, most of the time a user
will look at the syslog like output from journal, so we want the
timestamps there too.
- All internal source files (except "examples", which are not internal)
should include "config.h" first. As also all internal source
files should include "nm-default.h", let "config.h" be included
by "nm-default.h" and include "nm-default.h" as first in every
source file.
We already wanted to include "nm-default.h" before other headers
because it might contains some fixes (like "nm-glib.h" compatibility)
that is required first.
- After including "nm-default.h", we optinally allow for including the
corresponding header file for the source file at hand. The idea
is to ensure that each header file is self contained.
- Don't include "config.h" or "nm-default.h" in any header file
(except "nm-sd-adapt.h"). Public headers anyway must not include
these headers, and internal headers are never included after
"nm-default.h", as of the first previous point.
- Include all internal headers with quotes instead of angle brackets.
In practice it doesn't matter, because in our public headers we must
include other headers with angle brackets. As we use our public
headers also to compile our interal source files, effectively the
result must be the same. Still do it for consistency.
- Except for <config.h> itself. Include it with angle brackets as suggested by
https://www.gnu.org/software/autoconf/manual/autoconf.html#Configuration-Headers
When the device is transitioning from unmanaged to disconnected for "assumed"
reason, bring_up is not called. This is not a good thing in numerous
instances, e.g.:
1.) vlans that we've created need that to set IFF_UP and read carrier
otherwise they won't be available for connections.
2.) veths that are being managed need to start the deferred carrier check
so that the behavior matches real Ethernet.
3.) Hardware devices that were plugged in while NetworkManager is running
that need the IFF_UP for a carrier check, possibly enqueueing a deferred one.

Like we already do for IPv6 addresses, we should expose addresses
in a defined, stable sort order.
Clients usually show the addresses in the same order as obtained
via D-Bus.
Sorry, it was not Debian's fault. It is only libnss-devel package on
Ubuntu 12.04/Precise [1].
Revert the workaround and avoid the failure by dropping the version check altogether.
NSS 3.11 is from 2006, it's unlikely a user tries to build current NetworkManager
against such an old version of the library.

Upon slave removal we unrealize the device, resetting the unmanaged
flags to NM_UNMANAGED_PLATFORM_INIT, then we clean up the device and
call nm_device_master_release_one_slave(), which asserts the presence
of NM_UNMANAGED_IS_SLAVE flag cleared just before.
Drop the check.

Since the device-for-all merge it's a sin (trips an assert) to create an
activation request with NULL device.
If we get here, it's probably that the master device exists, but is not ready
for activation (it's in UNMANAGED state in the process of being created).
Factories that overwrite this function are not supposed to chain
up the parent implementation. Thus there is no reason to have
a default implementation and it's clearer to inline it.
We not only want to check the device name when creating a virtual device, but
also when determining if the connection can actually be activated there.
Otherwise the device names will mix up if there's more connections that use
virtual devices of the same type.
Reuse the to-string function nm_platform_link_inet6_addrgenmode2str() to print the
addrgenmode for nm_platform_link_to_string().
Also, now we support NM_IN6_ADDR_GEN_MODE_STABLE_PRIVACY.
"nm-default.h" should only include all the relevant header files based
on NETWORKMANAGER_COMPILATION. It should not contain definitions on
it's own.
Move the definition of "bool" to "nm-macros-internal.h".
If we break the loop normally, @err must be already set to zero.
The only other way this can happen is when the credentials are
invalid. Move setting @err to there.
If @handle_events is FALSE, we want to drain the socket. In that case
even when encountering an error error we don't want to abort, but instead
continue reading the next message.
@abort_parsing is set TRUE at two places, which also explicitly
set @err to something. We don't want to reset @err and got to the
next @hdr. Instead error out first.
