[Since the change to strict refcounting for in_multi objects, this test
began to fail; formerly the refcount was a count of the number of requests
for a given address, NOT a count of pointers to the object.]
the first part before starting, or the TCP port we want to bind may be in
use still. Sleep for a short period between tests.
Use SIGTERM instead of SIGKILL.
multicast group using a raw socket, then removing the interface on which
the group is found, and joining a multicast group using a udp socket,
then removing the interface on which the group is found. An if_disc
interface is used as the interface on which to attach.
NB: A panic currently results from running this regression test, so do
so with caution.

- Test that the basic socket options have the right defaults, that we can
change them, read them back, etc.
- Add and remove some multicast addresses.
- Send a loopback multicast address and make sure it arrives intact.
There's more that could be done here, but it's a start.

other until the window is closed. Then one of the sockets is closed, which
will generate a RST once the TCP at the other socket does a window probe.
All versions of FreeBSD prior to 11/26/2004 will ignore this RST into a 0
window, causing the connection (and application) to hang indefinitely.
On patched versions of FreeBSD (and other operating systems), the RST
will be accepted and the program will exit in a few seconds.

Update README to describe the new protocol. The work's broken down into
two main sets of changes.
First, update the existing test programs (shell scripts and C programs)
to produce output in the ok/not ok format, and to, where possible, also
produce a header describing the number of tests that are expected to be
run.
Second, provide the .t files that actually run the tests. In some cases
these are copies of, or very similar too, scripts that already existed.
I've kept the old scripts around so that it's possible to verify that
behaviour under this new system (in terms of whether or not a test fails)
is identical to the behaviour under the old system.
Add a TODO file.
- Consistently use err/errx/warnx throughout, rather than using perror()
and exit().
- Teach the tests how to better manage (and therefore test) privilege:
in particular, how to create sockes with root credentials but exercise
the privileges with non-root credentials, etc.
- Teach the test suite to apply each of the non-IP_HDRINCL options across
each of SOCK_DGRAM, SOCK_STREAM, and SOCK_RAW.
atempts to read and write various IP-level socket options as root and
nobody, making sure the initial values are as expected, that they can
be changed to valid values and take effect, etc. No attempt is made
to check for the correct implementation of side effects (such as
changes in packet headers) as yet.
The IP options section is currently broken but will be fixed shortly.
Not all multicast options are currently tested.
