- Copy stable/10 (r259064) to releng/10.0 as part of the
10.0-RELEASE cycle.
- Update __FreeBSD_version [1]
- Set branch name to -RC1

[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so
start releng/10.0 at '100' so the branch is started with
a value ending in zero.

Add the cddl/ directory.

Simply running ``make world'' will bomb unless you dig up the
undocumented HISTORICAL_MAKE_WORLD variable and set it. Note it
here so the blow up will not really be a surprise to people who
read.

Link the buildingworld chapter of our handbook in the README
while I'm here.

Add a note explaining what the rescue/ directory is for.

KerberosIV de-orbit burn continues. Disconnect from "make world".

Fix broken handbook links.

Submitted by: "Dipl.Phys. Andreas Hiltenkamp" <hiltenkamp@web.de>

Spell "FreeBSD" correctly.

`buildworld' is no longer a strict prerequisite for `buildkernel'
as of Makefile.inc1,v 1.184.

Fix kernel configuration files path to look MI.

Mention src/kerberos5.

Slightly improve the description of "crypto". "DES" is a subset of
what we have in secure/.

secure/ may be exported now.

Point out, that build/installkernel need a built world and that more
information can be found in the handbook.

Reflect reality:
- Make world doesn't build the modules any more.
- Mention the buildkernel/installkernel targets as common used targets.
- LINT has gone, NOTES is new but cannot be built. It is a pure reference
file. However, I still mentioned LINT but pointed out the difference
between the ancient LINT and the new NOTES. This should avoid confusion.
- crypto/ subdir isn't export controlled any more.

$Id$ -> $FreeBSD$

No more src/lkm dir...

Correct the facts. The kerberosIV/ directory is not export restricted.

Re-alphabetize and update the subdir descriptions.

Note that /etc is not installed by world target either.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Typo (maybe), config(1) -> config(8).

Bring back the README, this time attempting to be a little more
informative about what the user is seeing here.
