getting-started, dev-manual: Created Layer Model section

This involved removing the general information about layers from
the dev-manual and incorporating it into the new section of the
getting-started manual.

             multiple layers.
             Layers allow you to isolate different types of customizations from
             each other.
-            You might find it tempting to keep everything in one layer when
-            working on a single project.
-            However, the more modular your Metadata, the easier
-            it is to cope with future changes.

-            To illustrate how layers are used to keep things modular, consider
-            machine customizations.
-            These types of customizations typically reside in a special layer,
-            rather than a general layer, called a Board Support Package (BSP)
-            Layer.
-            Furthermore, the machine customizations should be isolated from
-            recipes and Metadata that support a new GUI environment,
-            for example.
-            This situation gives you a couple of layers: one for the machine
-            configurations, and one for the GUI environment.
-            It is important to understand, however, that the BSP layer can
-            still make machine-specific additions to recipes within the GUI
-            environment layer without polluting the GUI layer itself
-            with those machine-specific changes.
-            You can accomplish this through a recipe that is a BitBake append
-            (<filename>.bbappend</filename>) file, which is described later
-            in this section.
-            <note>
-                For general information on BSP layer structure, see the
-                <ulink url='&YOCTO_DOCS_BSP_URL;#bsp'>Board Support Packages (BSP) - Developer's Guide</ulink>.

-                The <ulink url='&YOCTO_DOCS_REF_URL;#source-directory'>Source Directory</ulink>
-                contains both general layers and BSP
-                layers right out of the box.
-                You can easily identify layers that ship with a
-                Yocto Project release in the Source Directory by their
-                folder names.
-                Folders that represent layers typically have names that begin with
-                the string <filename>meta-</filename>.
-                <note>
-                    It is not a requirement that a layer name begin with the
-                    prefix <filename>meta-</filename>, but it is a commonly
-                    accepted standard in the Yocto Project community.
-                </note>
-                For example, when you set up the Source Directory structure,
-                you will see several layers:
-                <filename>meta</filename>,
-                <filename>meta-skeleton</filename>,
-                <filename>meta-selftest</filename>,
-                <filename>meta-poky</filename>, and
-                <filename>meta-yocto-bsp</filename>.
-                Each of these folders represents a distinct layer.
-            </para>

-            <para>
-                As another example, if you set up a local copy of the
-                <filename>meta-intel</filename> Git repository
-                and then explore the folder of that general layer,
-                you will discover many Intel-specific BSP layers inside.
