After the merge request !22 was created, this bug was fixed in !23,
the associated branch was used for local tests, but the fix was not
transferred to !22. After merging !22 into the master branch and
rebasing !23 to the master, this fix was lost.

This should avoid test failures under CMake in which the
dbus-daemon inherits an unwanted fd from CMake's test framework, causing
the close-on-exec check before executing activated services to fail.
The dbus-daemon now marks all fds that it inherits, except for its
stdin, stdout and stderr, to be closed on exec. For completeness, the
dbus-daemons run by dbus-run-session and dbus-launch also now inherit
stdin, stdout, stderr and the pipes used to communicate with their
callers, but nothing else.

stdout and stderr are close-on-exec and buffered, so we can't rely on
their buffers being empty. If we continue to execute application code
after forking (as opposed to immediately exec()ing), then the child
process might later flush the libc stdio buffers, resulting in
output that is printed by the parent also being printed by the child.
In particular, test-bus.log sometimes grows extremely large for
this reason, because this test repeatedly attempts to carry out
legacy activation.

DBUS_SESSION_BUS_PID is not mandatory to set, but we should unset it
if present, since it points to a different session's bus. Likewise for
DBUS_SESSION_BUS_WINDOWID.
Similarly, if DBUS_STARTER_BUS_TYPE and DBUS_STARTER_ADDRESS
are set (as they would be under GNOME Terminal 3.8, see
<https://bugs.freedesktop.org/show_bug.cgi?id=63119>) then they
are likely to point to a different session's bus.

In Linux envrionment, signal.h included by sys/wait.h, however, this
isn't the case in FreeBSD. So explicit include it to fix build failure.
