kerberos libraries were not linked properly (missing dependencies),
which causes 3rd party applications linking to fail when --as-needed
ld flag is used. I also added the --no-undefined ld(1) flag to make
sure that there're no missing dependencies.

Distinguish IPv4 and IPv6 addresses and optional port numbers in
user space to set the option for the correct protocol family.
Add support in the kernel for carrying the new IPv6 destination
address and port.
Add support to TCP and UDP for IPv6 and fix UDP IPv4 to not change
the address in the IP header.
Add support for IPv6 forwarding to a non-local destination.
Add a regession test uitilizing VIMAGE to check all 20 possible
combinations I could think of.

Ensure that process descriptors work as expected. We should be able to:
- pdfork(), like regular fork(), but producing a process descriptor
- pdgetpid() to convert a PD into a PID
- pdkill() to send signals to a process identified by a PD

This commit adds regression testing for openat(), fstatat(), etc. with
capability scoping ("strict relative" lookup), which applies:
- in capability mode
- when performing any *at() lookup relative to a capability
These tests will fail until the *at() code is committed; on my local
instance, with the *at() changes, they all pass.

As per kib's suggestion, we also change test_count from a size_t to an int;
its value at the moment is 4, and we only expect it to go up to 7.

kernel for FreeBSD 9.0:
Add a new capability mask argument to fget(9) and friends, allowing system
call code to declare what capabilities are required when an integer file
descriptor is converted into an in-kernel struct file *. With options
CAPABILITIES compiled into the kernel, this enforces capability
protection; without, this change is effectively a no-op.
Some cases require special handling, such as mmap(2), which must preserve
information about the maximum rights at the time of mapping in the memory
map so that they can later be enforced in mprotect(2) -- this is done by
narrowing the rights in the existing max_protection field used for similar
purposes with file permissions.
In namei(9), we assert that the code is not reached from within capability
mode, as we're not yet ready to enforce namespace capabilities there.
This will follow in a later commit.
Update two capability names: CAP_EVENT and CAP_KEVENT become
CAP_POST_KEVENT and CAP_POLL_KEVENT to more accurately indicate what they
represent.

Even if we have CAP_FCHFLAGS, fchflags(2) fails on NFS. This is normal
and expected, so don't fail the test because of it.
Note that, whether or not we are on NFS, fchflags(2) should always fail
with ENOTCAPABLE if we are using a capability that does not have the
CAP_FCHFLAGS right.

Formerly, in this case an error was returned but the pid was also returned
to the application, requiring the application to use unspecified behaviour
(the returned pid in error situations) to avoid zombies.
Now, reap the zombie and do not return the pid.

Rather than using err() if either of two failure conditions
fires (which can produce spurious error messages), just use
errx() if the one condition that really matters fires.
In practice, this single test is enough to detect the failure
mode we're looking for (kqueue being inherited across fork).

Modify the existing unit test (from libkqueue) which already exercises process events via
fork() and kill(). Now, the child process simply checks that the 'kqfd' descriptor is invalid.
Some minor modifications were required to make err() work correctly. It seems that this test
was imported using the output of a configure script, but config.h was not included in key
places, nor was its syntax correct (need '#define HAVE_FOO 1' rather than '#define HAVE_FOO').
Finally, change main() to run the "proc" suite by default, but widened the '#if TODO' in
proc.c to include the non-functioning test event_trigger().

This knob removes the tools that are exclusively used to view and
maintain the databases maintained by utmpx, namely last, users, who,
wtmpcvt, ac, lastlogin and utxrm.
The tool w is not in this list, because it has some other functionality
which is unrelated to utmpx; it is hardlinked to the uptime tool.

The WITHOUT_ACCT switch is supposed to omit tools related to process
accounting, namely accton and sa. ac(8) is just a simple tool that
prints statistics based on data in the utx.log database. It has nothing
to do with the former.

Replacing ;; with the new control operator ;& will cause the next list to be
executed as well without checking its pattern, continuing until a list ends
with ;; or until the end of the case statement. This is like omitting
"break" in a C "switch" statement.
The sequence ;& was formerly invalid.
This feature is proposed for the next POSIX issue in Austin Group issue
#449.

The eval special builtin now runs the code with EV_EXIT if it was run
with EV_EXIT itself.
In particular, this eliminates one fork when a command substitution contains
an eval command that ends with an external program or a subshell.
This is similar to what r220978 did for functions.

Example:
case x in [[:alpha:]]) echo yes ;; esac

This is required by POSIX, and allows things like ENV=\$HOME/.shrc.

The function name expandstr() and the general idea of doing this kind of
expansion by treating the text as a here document without end marker is from
dash.
All variants of parameter expansion and arithmetic expansion also work (the
latter is not required by POSIX but it does not take extra code and many
other shells also allow it).
Command substitution is prevented because I think it causes too much code to
be re-entered (for example creating an unbounded recursion of trace lines).
Unfortunately, our LINENO is somewhat crude, otherwise PS4='$LINENO+ ' would
be quite useful.

If the here-document is attached to a compound command or subshell, $?
already works properly. This is both a workaround for bin/41410 and a

It would be nice if this test also exercised packet diversion and
injection, but that is for another day.
