Handle the iptables, dnsmasq and dnssec-trigger paths in the same way
through common code.
The path set by user must be accepted as is, even if does not exist,
because this is a requirement for cross-compilation. When user does
not specify a path, search a predefined set of paths and fall back to
an hardcoded one.

If the library is available, let's at least compile both
crypto backends.
That is helpful when developing on crypto backends, so that
one does not have to configure the build twice.
With autotools, the build is only run during `make check`.
Not for meson, but that is generally the case with our meson
setup, that it also builds tests during the regular build step.
suspend-resume must be selectable, out of for possible options.
We can do auto-detection based on present libraries, but it
shall be selectable. Like it is with autotools.
- always define the SESSION_TRACKING_* defines to replace
"#ifdef" with "#if".
- drop defining the consolekit database path CKDB_PATH in
config.h. The path was not customizable via configure/meson.
- fix meson build to enable consolekit support for session tracking
without also enabling logind/elogind session tracking.
logind/elogind is mutually exclusive, but consolekit session tracking
goes together just fine.
1) the command line gets shorter. I frequently run `make V=1` to see
the command line arguments for the compiler, and there is a lot
of noise.
2) define each of these variables at one place. This makes it easy
to verify that for all compilation units, a particular
define has the same value. Previously that was not obvious or
even not the case (see commit e5d1a71396
and commit d63cf1ef2f).
The point is to avoid redundancy.
3) not all compilation units need all defines. In fact, most modules
would only need a few of these defines. We aimed to pass the necessary
minium of defines to each compilation unit, but that was non-obvious
to get right and often we set a define that wasn't used. See for example
"src_settings_plugins_ibft_cppflags" which needlessly had "-DSYSCONFDIR".
This question is now entirely avoided by just defining all variables in
a header. We don't care to find the minimum, because every component
gets anyway all defines from the header.
4) this also avoids the situation, where a module that previously did
not use a particular define gets modified to require it. Previously,
that would have required to identify the missing define, and add
it to the CFLAGS of the complation unit. Since every compilation
now includes "config-extra.h", all defines are available everywhere.
5) the fact that each define is now available in all compilation units
could be perceived as a downside. But it isn't, because these defines
should have a unique name and one specific value. Defining the same
name with different values, or refer to the same value by different
names is a bug, not a desirable feature. Since these defines should
be unique accross the entire tree, there is no problem in providing
them to every compilation unit.
6) the reason why we generate "config-extra.h" this way, instead of using
AC_DEFINE() in configure.ac, is due to the particular handling of
autoconf for directory variables. See [1].
With meson, it would be trivial to put them into "config.h.meson".
While that is not easy with autoconf, the "config-extra.h" workaround
seems still preferable to me.

After 1.12.0 is released, merge it back into master so that
1.12.0 is part of the history of master. That means,
$ git log --first-parent master
will also traverse 1.12.0 and 1.12-rc*.
Also bump the micro version to 1.13.1-dev to indicate that this is
after 1.12.0 is out.
This makes package updates more robust, avoiding in-place replaces of
the plugins.
Previously, if an upgrade transaction was terminated, NetworkManager
library could end up being of a different version than the plugins.
If the user was unfortunate enough to connect using a connection that
required a plugin (say, Wi-Fi), he would be left without a network
connection making it somewhat inconvenient to recover from the botched
upgrade.
This makes the whole situation a little bit less sad.
The VPN plugins are kept where they always have been -- the path is not
qualified with a version number.
With autotools, we use libtool so that the right libraries are
automatically found. Still, we won't find the right GI typelib.
Add a mechanism so that when make/meson invokes the run-nm-test.sh
runner, it passes the build-root directory.
Also, try to autodetect when invoked manually.

Supporting PolicyKit required no additional library, just extra code
to handle the D-Bus calls. For that, there was a compile time option
to even stip out that code. Note, that you could (and still can)
configure the system not to use policy-kit. The point was to reduce
the binary size in case you don't need it.
Remove this. I guess, we we aim for such aggressive optimization of
the binary size, we should instead make all device types disablable
at configuration time. We don't do that either and other low hanging
fruits, because it's better to always enable features, unless they
require external dependencies.
Also, the next commit will make more use of NMAuthManager. So, having
it disabled at compile time, makes even less sense.
From libnl3, we only used the helper function to parse/generate netlink
messages and the socket functions to send/receive messages. We don't
need an external dependency to do that, it is simple enough.
Drop the libnl3 dependency, and replace all missing code by directly
copying it from libnl3 sources. At this point, I mostly tried to
import the required bits to make it working with few modifications.
Note that this increases the binary size of NetworkManager by 4736 bytes
for contrib/rpm build on x86_64. In the future, we can simplify the code
further.
A few modifications from libnl3 are:
- netlink errors NLE_* are now in the domain or regular errno.
The distinction of having to bother with two kinds of error
number domains was annoying.
- parts of the callback handling is copied partially and unused parts
are dropped. Especially, the verbose/debug handlers are not used.
In following commits, the callback handling will be significantly
simplified.
- the complex handling of seleting ports was simplified. We now always
let kernel choose the right port automatically.
XXX was used to either raise attention (NOTE) or to indicate
that this is ugly code that should be fixed (FIXME). The usage
was inconsistent.
Let's avoid XXX and use either NOTE or FIXME.
The check doesn't seem useful, because it does not result in a fallback
or a different build.
Just assume <linux/wireless.h> is valid. In case it is not, we will get a
build failure later. That is just as good.

netlink's API is stable, and strictly defined by the integer values that make
up commands and attributes. There is little reason do disable a netlink feature
based on compile time detection of the kernel headers.
Either kernel supports it, or it will fail with an appropriate response.
Also, support for NL80211_CMD_CRIT_PROTOCOL_START was merge to kernel
in 2013. Maybe, we should now just always assume support (in the kernel
headers is there). Anyway, don't do that yet, but instead avoid the
defines and use the numeric values directly.
We also unconditionally use them with autotools.
Also, the detection for have_version_script does
not seem correct to me. At least, it didn't work
with clang.
The strings holding the names used for libraries have also been
moved to different variables. This way they would be less error
as these variables can be reused easily and any typing error
would be quickly detected.
In a recent commit 1402fa7487 a new
way for testing Red Hat compatible distributions had been added.
However, this new approach does not use a set of files, it uses a
directory, so this test can be done by using the `test` command
and makes the `check_distro.py` script unnecessary.
