o Use the common pci_* routines in preference to the copied and hacked
routines from an ancient pci.c.
This saves 509 lines in cardbus.c. More savings to follow when I
convert the resource code over. In the past when I've done this the
resource code conversion breaks cardbus in subtle ways so I'm doing a
1/2 way checkpoint this time. cardbus still works for me the same as
it did before.
It also looks like cardbus devices now show up as pci bus devices to
pciconf -l, but maybe that was happening before.
Inspired by a patch from Justin Gibbs many moons ago. When he
finishes his kobj multiple inheritance work, we can transition the
finished version of this work to that fairly easily.
but it's no longer a part of the base-system and buildworld works fine
here after deleting them both on disk and from the mtree spec files.

- Mark the process leader as having an advisory lock
- Check if process leader is marked as having advisory lock when
closing file
- Check that file is still open after lock has been obtained
- Don't allow file descriptor table sharing between processes
with different leaders

The result of this bug was bad scaling of the VHPT relative to the
available memory.

It's unnecessary for two reasons: (1) Giant is at present already held in
such cases and (2) our various implementations of pmap_growkernel() look to
be MP safe. (For example, for sparc64 the proof of (2) is trivial.)
few bugs for a few corner cases and correctly handle the case where
read(2) is read()'ing from a non-file descriptor and could get fewer
bytes back than the buffer, but it isn't EOF[2]. random(6) extensively
tested and believed to be bug free (save performance for large files).

freebsd4_sigaction() and osigaction() instead of around the whole
body of those functions. They now no longer hold Giant around calls
to copyin() and copyout(), and it is slightly more obvious what
Giant is protecting.
