For the moment, the CMake build system only knows about the existing
"embedded tests"; make it define both symbols, though.
We use GLib because it has GTester (and life's too short to write yet another
JUnit clone), and dbus-glib for the main-loop integration only (see
fd.o #31515 for thoughts on incorporating just those two functions in a
separate library in the dbus tarball).
I'm not using DBusLoop for the main loop because I specifically don't
want to use non-public API or ABI of libdbus in the modular tests. If we make
sure they work against a shared libdbus, we can use them to test the
installed system, with "make installcheck".

We no longer use GLib internally, and assertions are how it'll report test
failures when we add GTest-based tests.

Trying to mix atomic operations with locked non-atomic operations is
broken: the atomic ops aren't necessarily atomic with respect to the
locked non-atomic ops, and the non-atomic ops aren't protected by the
lock because the atomic ops can change the refcount behind their back.
In theory we could use the connection lock if atomic ops aren't supported
(making a per-connection lock cheaper than the global lock used to
implement atomic ops) *and* our mutexes are recursive (making it safe
against deadlocks)... but life's too short.

Using $(LN_S) is inappropriate because it could in theory mean either
ln -s, ln or cp -p depending on autoconf checks.
Not using -f breaks reinstallation directly from source (DESTDIR unset),
because the symlinks will already exist.
Because systemd isn't currently portable to non-Linux, let alone
non-SUS-compliant systems, it seems safe to assume that ln -fs behaves
as specified by SUS if systemd was found.

Packagers should only enable this flag if they have confirmed that it
actually works on their toolchain (it's the sort of rarely used feature
that frequently regresses on obscure architectures/OSs without anyone
noticing), and also confirmed that it is actually a significant size win
for their configuration.

On Linux, we previously called openlog() (with different options!) while
initializing SELinux; leave SELinux messages as LOG_USER|LOG_INFO in case
anyone was relying on that, but let the rest of our log messages come
out as LOG_DAEMON.
Also enable LOG_PERROR (copy syslog messages to stderr) unconditionally;
we can make this an autoconf check if anyone's pet Unix doesn't have
LOG_PERROR.

DBUS_ENABLE_X11_AUTOLAUNCH obviously requires DBUS_BUILD_X11. However,
the converse is not true.
If DBUS_BUILD_X11 is defined, dbus-launch will be able to connect to
the X server to determine when the session ends; most distributors will
want this, but it can be disabled with the standard Autoconf option
--without-x.
If DBUS_ENABLE_X11_AUTOLAUNCH is *also* defined, dbus-launch and libdbus
will be willing to perform autolaunch. Again, most distributors will want
this, but it can be disabled with --disable-x11-autolaunch.

Doing a malloc and a hex-encoding pass just to produce a _dbus_verbose

overkill, and this block had incorrect error handling (not checking the

In shell-like pseudocode, the desired result is:
if $use_subdir
dir = $tmpdir/dbus_nonce-$random
path = $dir/nonce
mkdir $dir
write file at $path
else
dir = $user_owned_place
path = $dir/dbus_nonce-$random
write file at $path
However, /nonce was accidentally appended to $dir instead of $path,
resulting in an attempt to mkdir /tmp/dbus_nonce-XXXX/nonce when
dbus_nonce-XXXX hadn't been created yet.

Newer systemd-based systems support a global machine ID with the same
metrics as the D-Bus machine ID, but more powerful semantics (for
example on ro media) in /etc/machine-id.
If the D-Bus machine ID cannot be read, fall back to the systemd machine
ID.
This is a first step towards allowing D-Bus to be started up during
early boot where /var is not available.
