sshd uses separate child_env. So, to make setusercontext() really does
something, environment must be switched before call and passed to child_env
back after it.
The error here was that modified environment not passed back to child_env,
so all variables that setusercontext() adds are lost, including ones from
~/.login_conf
Cast sizeof() to (int), as it's being compared against an int, not a size_t.
If i is changed to a size_t, it means the logic must be slightly changed later
in the flow, where --i is checked to be >= 0. I am not sure I want to make a
logic change to account for clearing up a warning, when an aesthetic one will
keep from modifying the logic.
Other harmless casts, that I think I've made in the right directions.
Make gpbc() an inline function, rather than an obfuscated macro, make its
scratch space local, rather than global. The previous macro used a dirty
hack (logical AND in place of a conditional) which would lead GCC to throw
a fit (rightly so) as the logical check, as well as the incrementation of
a variable, were not used for anything.
const'ify a few places where gcc3 yells. xstrdup() some global consts in
places where we xstrdup() when not using consts, but tried to assign them
to non-consts before.
Don't use execv(2) if we don't have the kind of arguments it wants.

in various extattr_*() calls to match the rest of the file. Originally,
these bits at the end looked more like style(9). This patch was submitted
by green by way of the TrustedBSD MAC tree, and I fixed a few problems
with it on the way through. Someone with more time on their hands should
convert the entire file to style(9); this commit is for diff reduction
purposes.

Merge xargs(1) with that of xMach.
Bring in xargs(1) changes to add -L and -I as per the Single Unix Specification
version 3. Proper exit status numbers are implemented, and the manual page has
been updated to reflect reality.
The code has been ANSIfied, and a new file has been added to xargs(1) to do the
substring substitution as SUSv3 requires.
Traditional behaviour should not be affected, use of -J should be deprecated
in favor of the more portable -I (though -J has been left, for now).

-stable machine via the old-school methods):
Use __FreeBSD_version in preference to __FreeBSD__ >= N where possible.
Define a single variable mythread which is set to curproc or curthread
depending on the OS version (with a comment saying it is a white lie on
4.x since it really is a proc).
NB: __FreeBSD__ is the OS level of the host machine, not the target,
and should never be used, if possible, as __FreeBSD__ >= N.
for what is currently the '-p' parameter. '-s' is what NetBSD
used (and they implemented it before I added -p in FreeBSD), and
it also matches the '-s' option in syslogd. Someone in OpenBSD
land had also talked about adding a '-s' option, but it hasn't
happened yet.

$FreeBSD$ identifiers, and fix initialisation to stderr to happen in a function
as stderr is not the same in CURRENT as in OpenBSD.

constructing a struct aio and invoking VOP_READ() directly. This cleans
up the code a little, but also has the advantage of making sure almost
all vnode read/write access in the kernel goes through the helper
function, meaning that instrumentation of that helper function can impact
almost all relevant read/write operations. In this case, it permits us
to put MAC hooks into vn_rdwr() and not modify uipc_syscalls.c (yet).
In general, if helper vn_*() functions exist, they should be used in
preference to direct VOP's in system call service code.
