fbbd9655e5 Renumber copyright clause 4
Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

ccfb965433 Add META_MODE support.
Off by default, build behaves normally.
WITH_META_MODE we get auto objdir creation, the ability to
start build from anywhere in the tree.

Still need to add real targets under targets/ to build packages.

2966d28c32 Significantly reduce the memory leak as noted in BUGS section for
setenv(3) by tracking the size of the memory allocated instead of using
strlen() on the current value.

Convert all calls to POSIX from historic BSD API:
 - unsetenv returns an int.
 - putenv takes a char * instead of const char *.
 - putenv no longer makes a copy of the input string.
 - errno is set appropriately for POSIX.  Exceptions involve bad environ
   variable and internal initialization code.  These both set errno to
   EFAULT.

Several patches to base utilities to handle the POSIX changes from
Andrey Chernov's previous commit.  A few I re-wrote to use setenv()
instead of putenv().

New regression module for tools/regression/environ to test these
functions.  It also can be used to test the performance.

Bump __FreeBSD_version to 700050 due to API change.

ba174a5e38 Back out all POSIXified *env() changes.
Not because I admit they are technically wrong and not because of bug
reports (I receive nothing). But because I surprisingly meets so
strong opposition and resistance so lost any desire to continue that.

Anyone who interested in POSIX can dig out what changes and how
through cvs diffs.

a88ab48624 Ignore SIGSYS when BSM is compiled in. Otherwise, attempt to invoke su on
system that don't have audit framefork compiled into kernel or ia32 binary
on amd64 system will result in SIGSYS. There is one place in su.c itself
where it tries to check for errno != ENOSYS, but it has been a nop since su
does not catch SIGSYS anyway. There are few other places in libbsm,
where attempt to invoke audit syscal would result in SIGSYS if no audit
support is present in the kernel, so that the only reliable method for
now is to disable SIGSYS completely in the case when BSM is compiled in.

In the long run, both direct invocation of audit-related syscalls and
libbsm should be made more intellegent to handle the case when BSM is not
compiled into the kernel gracefully.

6319ad282f Integrate audit_submit(3) bits into su. This means that records for
successful and failed su attempts will be recorded using the AUE_su
event type (login or lo class) if auditing is present in the system.
Currently, the records will have a header, subject, text (with the
actual diagnostics), a return and trailer token.

See audit_submit(3) for more information.

cd17a1f7ba Fix the other su bug reintroduced two commits ago, namely
$ su
    % kill -STOP $$

where su is executing (t)csh.  csh's job handling is a little more
special than that of (a)sh, bash and even zsh and blows up a little
more spectacularly.  This modification restores the original mucking
about with the tty pgrp, but is careful to only do it when su (or
su's child) is the foreground process.

While I'm here, fix a STDERR_FILENO spelling as suggested by bde.

d43e192e7d Remove broken code that mucks about with tcsetpgrp() -- even if
su isn't the foreground process.  Hopefully this won't break PAM,
but I couldn't find any useful information about ache's theory
that it will.

Specifically, this change fixes the following:

    # sh
    # echo $$
    # su - root -c id &
    # echo $$

The PID output changes as su seems to be kill -STOP'ing itself
and catching the parent shell in the process.  This is especially
bad if you add a ``su - user -c command &'' to an rc script!
