When libdbus-1 moved to using monotonic time support for the
DBUS_COOKIE_SHA1 authentication was broken, in particular
interoperability with non-libdbus-1 implementations such as GDBus.
The problem is that if monotonic clocks are available in the OS,
_dbus_get_current_time() will not return the number of seconds since
the Epoch so using it for DBUS_COOKIE_SHA1 will violate the D-Bus
specification. If both peers are using libdbus-1 it's not a problem
since both ends will use the wrong time and thus agree. However, if
the other end is another implementation and following the spec it will
not work.
First, we change _dbus_get_current_time() back so it always returns
time since the Epoch and we then rename it _dbus_get_real_time() to
make this clear. We then introduce _dbus_get_monotonic_time() and
carefully make all current users of _dbus_get_current_time() use it,
if applicable. During this audit, one of the callers,
_dbus_generate_uuid(), was currently using monotonic time but it was
decided to make it use real time instead.

As with the optional test-dependencies on GLib and dbus-glib, we make this
a hard dependency if --enable-tests[=yes], but not if --enable-tests=auto.

This is the library used by tests that link libdbus-internal and DBusLoop.
By linking libdbus-internal into it, we can avoid having to repeat that
dependency all over the place - libtool and cmake both know how to follow
recursive dependencies.
In cmake, also use libdbus-testutils for more tests, in preference to
repeating its source files.
These tests get everything they need from the public or internal API of
libdbus-internal.la, and libtool knows how to pull in libraries'
dependencies, so we don't need explicit linking.
spawn-test and break-loader don't actually need test-utils.[ch]
either.
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.

This fixes a race condition: the server exits while the client continues
to the next iteration. If the server wins, the test passes. If the client
wins, it sends a message to the dying service, never gets a reply, and the
test fails.
My branch to refactor the main loop for fd.o #23194 seems to make the
client more likely to win this race, resulting in intermittent test
failures.
This is an instance of the general problem described by fd.o #11454.
This reverts commit 4626b40560.
test-autolaunch works fine in non-launchd environments (and non-X11
environments, based on a quick test passing enable_x11=no to configure).
On the contrary: this commit *broke* the build on non-launchd
environments, because test/name-test/run-test.sh still tried to run this
test even if it hadn't been built.
* test/name-test/test-autolaunch.c: New file,
unsets DBUS_SESSION_BUS_ADDRESS so we should
fall back to autolaunch:.
* test/name-test/run-test.sh: Run it.
* test/name-test/Makefile.am: Build it.
This test, while extensive, has the serious flaw of effectively
spinning on _dbus_connection_do_iteration_unlocked. Any tests
like this should be using the internal DBus mainloop, which
I don't have time to port it to before doing a release.
A variety of system components have migrated from legacy init into DBus
service activation. Many of these system components "daemonize", which
involves forking. The DBus activation system treated an exit as an
activation failure, assuming that the child process which grabbed the
DBus name didn't run first.
While we're in here, also differentiate in this code path between the
servicehelper (system) versus direct activation (session) paths. In
the session activation path our error message mentioned a helper
process which was confusing, since none was involved.

Our previous fix went too far towards lockdown; many things rely
on signals to work, and there's no really good reason to restrict
which signals can be emitted on the bus because we can't tie
them to a particular sender.
