1. Don't do upgrade_checks when using bmake. As long as we have WITH_BMAKE,
there's a bootstrap complication in ths respect. Avoid it. Make the
necessary changes to have upgrade_checks work wth bmake anyway.
2. Remove the use of -E. It's not needed in our build because we use ?= for
the respective variables, which means that we'll take the environment
value (if any) anyway.
3. Properly declare phony targets as phony as bmake is a lot smarter (and
thus agressive) about build avoidance.
4. Make sure CLEANFILES is complete and use it on .NOPATH. bmake is a lot
smarter about build avoidance and should not find files we generate in
the source tree. We should not have files in the repository we want to
generate, but this is an easier way to cross this hurdle.
5. Have behavior under bmake the same as it is under make with respect to
halting when sub-commands fail. Add "set -e" to compound commands so
that bmake is informed when sub-commands fail.
6. Make sure crunchgen uses the same make as the rest of the build. This
is important when the make utility isn't called make (but bmake for
example).
7. While here, add support for using MAKEOBJDIR to set the object tree
location. It's the second alternative bmake looks for when determining
the actual object directory (= .OBJDIR).

* jail_setv will leak a parameter name if jailparam_import fails.
* jailparam_all loses the jailparam pointer on realloc error
(a clear freshman mistake).
* If jailparam_init fails, the caller doesn't need to jailparam_free
the buffer. That's not really clear, so set things to NULL allowing
jailparam_free to work without error (though it's still not required).
After further discussion, instead of pretending to use
uid_t and gid_t as upstream Solaris and linux try to, we
are better using u_int, which is in fact what the code
can handle and best approaches the range of values used
by uid and gid.

The previous change (based on Solaris) doesn't work properly either
as the casting only has the effect of quieting the compiler.
Move back to the previous solution but adjust the sizeof()
type in xdr_array(). This should mostly work (by accident).

1) Don't iterate the loop from the environment array beginning each time,
iterate it under the last place we deactivate instead.
2) Call __rebuild_environ() not on each iteration but once, only at the end
of whole loop (of course, only in case if something is changed).

As part of the previous commit, uses of xdr_int() were replaced
with xdr_u_int(). This has undesired effects as the second
argument doesn't match exactly uid_t or gid_t. It also breaks
assumptions in the size of the provided types.
To work around those issues we revert back to the use of xdr_int()
but provide proper casting so the behaviour doesn't change.
While here fix a style issue in the affected lines.

This fixes a race condition where another thread may fork() before CLOEXEC
is set, unintentionally passing the descriptor to the child process.
This commit only adds O_CLOEXEC flags to open() or openat() calls where no
fcntl(fd, F_SETFD, FD_CLOEXEC) follows. The separate fcntl() call still
leaves a race window so it should be fixed later.
Because fts keeps internal file descriptors open across calls, making such
descriptors close-on-exec helps not only multi-threaded applications but
also single-threaded applications.
In particular, this prevents passing a temporary file descriptor for saving
the current directory to processes created via find -exec.
The attempt to merge changes from the linux libtirpc caused
rpc.lockd to exit after startup under unclear conditions.
After many hours of selective experiments and inconsistent results
the conclusion is that it's better to just revert everything and
restart in a future time with a much smaller subset of the
changes.

Passing an invalid pointer results in undefined behaviour.
The wrappers in libthr access some of the data pointed to by the arguments
in userland, so that an invalid pointer will cause a signal and not an
[EFAULT] error return.
Furthermore, if the [EFAULT] error occurs when the kernel is writing, it is
not a proper error in the sense that the call still commits (changing the
signal disposition or accepting the signal).

as an optimization, but we are getting closer to supporting
applications and/or kernels that change the (FreeBSD i386) default

and this requires the STRICT_ALIGN()s that were added to support
FP_PE to actually work in all precisions.

it is done in NetBSD/OpenBSD, and as it was here before r205728.
I personally think this API or its implementation is incorrect, as it is not
correct to filter collections based on report ID, as they are orthogonal
in general case, but I see no harm from supporting this feature.
