* dbus/dbus-sysdeps.c (_dbus_become_daemon): write the pidfile
here in the parent process, so we can return an error if it
fails. Also, move some of the code into the child so the parent
is less hosed if we fail midway through.
* bus/bus.c (bus_context_new): move pidfile detection further up
in the function, before we start overwriting sockets and such.
* bus/messagebus.in: adjust this a bit, not sure if it will work.
* configure.in: add --with-system-pid-file and --with-system-socket
