This patch fixes warnings from '-Wsuggest-attribute=noreturn'. We cannot
enable it unconditionally as it would break libtool.

As a side benefit, this means that dbus-launch now understands
/etc/machine-id and not just /var/lib/dbus/machine-id.
Since machine_uuid comes out of libdbus allocated with dbus_malloc,
to avoid having to copy it from malloc-allocated to
dbus_malloc-allocated storage, it makes sense to change it to be
consistently dbus_malloc-allocated (particularly now that Bug #83115
has made use of internal symbols relatively painless). However, I'm
deliberately not changing the allocation model of any other strings
in dbus-launch right now; that's a larger yak-shaving exercise.
* tools/dbus-launch.c (print_variables): if no syntax is given,
don't print something that's sort-of-half-sh-syntax, just print
a plain key-value pairs thing.
* tools/dbus-launch-x11.c: use machine ID rather than hostname for
the local machine representation (but still have the hostname in
the display). Remove the hostname from the display if it is
localhost. Change session files to be named
~/.dbus/session-bus/machine-display. Change X atoms to be
underscore-prefixed so nobody whines about ICCCM compliance.
Otherwise name them the same as the env variables.
Change session file format to include key-value pairs and an
explanatory comment. Keys are the same as the env variables.
(set_address_in_x11): X property format can't depend on
sizeof(pid_t) on a particular machine, fix to always be 32 bits
* tools/dbus-launch.c: make --autolaunch take a machine id
argument. If --autolaunch is used with a program to run, complain
for now (but add a FIXME). Also, don't look for existing bus if
there's a program to run (but add a FIXME).
* dbus/dbus-sysdeps-unix.c (_dbus_get_autolaunch_address): pass
machine uuid to dbus-launch (avoids linking dbus-launch to libdbus
just to get this, and avoids duplicating uuid-reading code).
* tools/dbus-launch.1: clarify various things
* tools/dbus-launch.c
* tools/dbus-launch.h
* tools/dbus-launch-x11.c:
* tools/dbus-launch.1: Add the --autolaunch option to
dbus-launch, which makes it scan for an existing session
started with --autolaunch. With that option, it also creates
an X11 window and saves the bus address and PID to it.
* dbus/dbus-sysdeps.h:
* dbus/dbus-sysdeps-unix.c (_dbus_get_autolaunch_address): Add
a function that runs "dbus-launch --autolaunch" to retrieve
the running D-Bus session address (or start one if none was running)
* dbus/dbus-transport.c: Add the handler for the "autolaunch:"
address protocol, which tries to get the running session from
dbus-launch.
* dbus/dbus-bus.c:
* dbus/dbus-internals.h: Make "autolaunch:" be the default
D-Bus session bus address.
* dbus/dbus-connection.c: Fix horrible typo in error message.
