Fix a race condition between kern_wait() and thread_stopped().
Problem is in kern_wait(), parent process steps through children list,
once a child process is skipped, and later even if the child is stopped,
parent process still sleeps in msleep(), the race happens if parent
masked SIGCHLD.

into _bus.h to help with name space polution from including all of bus.h.
In a few days, I'll commit changes to the MI code to take advantage of thse
sepration (after I've made sure that these changes don't break anything in
the main tree, I've tested in my trees, but you never know...).

While we wait for holds to be released, print a list of who holds us
back once per second.
Use the new KPI from GEOM instead of vfs_mount.c calling g_waitidle().
Use the new KPI also from ata.
With ATAmkIII's newbusification, ata could narrowly miss the window
and ad0 would not exist when we tried to mount root.
mac_check_proc_wait(), which control the ability to wait4() specific
processes. This permits MAC policies to limit information flow from
children that have changed label, although has to be handled carefully
due to common programming expectations regarding the behavior of
wait4(). The cr_seeotheruids() check in p_canwait() is #if 0'd for
this reason.
The mac_stub and mac_test policies are updated to reflect these new
entry points.

dc0: MII without any PHY!
We have to enable the connection to the MII first. Doing so fixes the
problem cards without breaking the older, working cards.

particular, acl support is no longer enabled on FreeBSD 4, acl support
should be correctly enabled on Linux, dirent.d_namlen should be
correctly detected on platforms that support it.
