* dbus/dbus-message.c (_dbus_message_test): add more test
coverage, but #if 0 for now since they uncover a bug
not fixed yet; I think in re_align_field_recurse()
(re_align_field_recurse): add FIXME about broken assertion
* dbus/dbus-sysdeps.c (_dbus_sysdeps_test): add more test coverage
* bus/connection.c: share a couple code bits with expirelist.c
* bus/expirelist.h, bus/expirelist.c: implement a generic
expire-items-after-N-seconds facility, was going to share between
expiring connections and replies, decided not to use for expiring
connections for now.
* bus/connection.c: add tracking of expected replies
* COPYING: include AFL 2.0 (still need to change all the file headers)
* tools/dbus-cleanup-sockets.c: add utility to clean up sockets
in /tmp (though on Linux this will end up being useless,
when we add abstract namespace support)
* configure.in: define DBUS_SESSION_SOCKET_DIR in addition to
subst'ing it
