notes document. Basically, I've moved the contents of common/
{artheader,intro,upgrading}.sgml into common/new.sgml, removed duplicate
$FreeBSD$ markers, and adjusted the various references to these files.
No other whitespace or content changes.
This change will make it easier to do some minor restructuring.

been a no-op for as long as our CVS history goes back. Processes in
state SSLEEP could only be counted if p_slptime == 0, but immediately
before loadav() is called, schedcpu() has just incremented p_slptime
on all SSLEEP processes.
missed in the previous commit; a line that exceeded 80 characters. No
functional changes, but the object file's md5 checksum changes because some
lines have been displaced.
1) Allow the sending of more than one control message at a time
over a unix domain socket. This should cover the PR 29499.
2) This requires that unp_{ex,in}ternalize and unp_scan understand
mbufs with more than one control message at a time.
3) Internalize and externalize used to work on the mbuf in-place.
This made life quite complicated and the code for sizeof(int) <
sizeof(file *) could end up doing the wrong thing. The patch always
create a new mbuf/cluster now. This resulted in the change of the
prototype for the domain externalise function.
4) You can now send SCM_TIMESTAMP messages.
5) Always use CMSG_DATA(cm) to determine the start where the data
in unp_{ex,in}ternalize. It was using ((struct cmsghdr *)cm + 1)
in some places, which gives the wrong alignment on the alpha.
(NetBSD made this fix some time ago).
This results in an ABI change for discriptor passing and creds
passing on the alpha. (Probably on the IA64 and Spare ports too).
6) Fix userland programs to use CMSG_* macros too.
7) Be more careful about freeing mbufs containing (file *)s.
This is made possible by the prototype change of externalise.

MFC after: 6 weeks
Instead of using 22 as the default cylinders per cylinder group parameter
(the max. value for a 8k/1k FS), compute the maximum value allowed and use
it. It can be overridden by specifying -c of course. This allow for FS built
through the initial installation to have better values.
<machine/ansi.h> for the definition of __signed, unless the compiler
is gcc.
Moved the declaration of socklen_t up together with the declaration of
size_t, and removed low-quality comment about this declaration. Declaring
socklen_t in this file is normal in POSIX-1.200x, unlike declaring size_t.
- bus_generic_map_intr.9. This has been undead for more than 3 years
following the changes in rev.1.4 of sys/bus.h.
- CONDSPLASSERT.9, SPLASSERT.9. These have been undead since SMPng.
They were even less useful than most section 9 man pages -- the
interfaces described in them have never been used in the FreeBSD
source tree.
