kernel-dev: Updates to get the new kernel-dev manual to make

These changes were to the intro chapter to introduce the DocBook
form, the Makefile to introduce the new manual, the figure used
for the title had to be updated, the root manual .XML file needed
changed, and the style sheet.

The manual now makes with just the raw text for Darren's intro
section.

-        The Yocto Project presents kernels as a fully patched, history-clean Git
-        repositories.
-        Each repository represents selected features, board support,
-        and configurations extensively tested by the Yocto Project.
-        Yocto Project kernels allow the end user to leverage community
-        best practices to seamlessly manage the development, build and debug cycles.
+        Regardless of how you intend to make use of the Yocto Project, chances are you
+are going to need to work with the Linux kernel. The Yocto Project provides a
+powerful set of tools for managing Linux kernel sources and configuration data.
+If you want to make a single configuration change, apply a couple of patches, or
+work with your own sources, the Yocto Project has tooling in place to help you
+do it.

-        This manual describes Yocto Project kernels by providing information
-        on history, organization, benefits, and use.
-        The manual consists of two sections:
-        <itemizedlist>
-            <listitem><para><emphasis>Concepts:</emphasis> Describes concepts behind a kernel.
-                You will understand how a kernel is organized and why it is organized in
-                the way it is.  You will understand the benefits of a kernel's organization
-                and the mechanisms used to work with the kernel and how to apply it in your
-                design process.</para></listitem>
-            <listitem><para><emphasis>Using a Kernel:</emphasis> Describes best practices
-                and "how-to" information
-                that lets you put a kernel to practical use.
-                Some examples are how to examine changes in a branch and how to
-                save kernel modifications.</para></listitem>
-        </itemizedlist>
+        Each Yocto Project release introduces a new set of linux-yocto kernel recipes,
+tracking the latest upstream developments and introducing newly supported
+platforms. In addition to the new kernel recipes, the previous recipes are
+refreshed and supported for at least one additional release. As they align,
+these previous releases are updated to include the latest from the LTSI project.
+Besides these recipes, a linux-yocto-dev recipe is available for working with
+the very latest in upstream Linux kernel development as well as meta-data
+development.

+        If you do not maintain your own kernel sources and need to make only minimal
+changes to the sources, these recipes provide a vetted base upon which to layer
+your changes. Doing so allows you to benefit from the continual kernel
+integration and testing performed during development of the Yocto Project.

-        For more discussion on the Yocto Project kernel, you can see these sections
-        in the Yocto Project Development Manual:
+        If, instead, you have a very specific Linux kernel source tree and are unable to
+align with one of the many official linux-yocto releases, an alternative
+exists by which you can use the Yocto Project Linux kernel tools with your own
+sources.
+    </para>
+
+    <para>
+        The sections that follow provide instructions for completing specific Linux
+kernel development tasks. They assume familiarity with working with bitbake
+recipes and basic open-source development tools. Understanding these concepts
+will facilitate the process of working with the kernel recipes. If you find you
+need some additional background, please be sure to review and understand the
+following documentation:
