bitbake: fetch2: Change git fetcher not to destroy old references

It looks like we're about to see a lot of changes in branch names in repos. If
we have the prune option here, those old names are lost, the changes propagate
to our source mirrors and our old releases break.

We have the force option so any replaced references should be replaced, its only
orphaned branches which will now be preserved.

I believe this behaviour will cause us fewer problems given the changes that
look likely to happen.

-        <filename>myarm</filename> as the machine name and <filename>qemu</filename>
-        as the machine architecture.
-        Of the available architectures, <filename>qemu</filename> is the only architecture
-        that causes the script to prompt you further for an actual architecture.
-        In every other way, this architecture is representative of how creating a BSP for
-        an actual machine would work.
-        The reason the example uses this architecture is because it is an emulated architecture
-        and can easily be followed without requiring actual hardware.

-        It might not be immediately clear how you can use the Yocto
-        Project in a team development environment, or scale it for a large
-        team of developers.
-        One of the strengths of the Yocto Project is that it is extremely
-        flexible.
-        Thus, you can adapt it to many different use cases and scenarios.
-        However, these characteristics can cause a struggle if you are trying
-        to create a working setup that scales across a large team.

-        To help you understand how to set up this type of environment,
-        this section presents a procedure that gives you the information
-        to learn how to get the results you want.
-        The procedure is high-level and presents some of the project's most
-        successful experiences, practices, solutions, and available
-        technologies that work well.
-        Keep in mind, the procedure here is a starting point.
-        You can build off it and customize it to fit any

-                and a single maintainer handles the final "top-of-tree" merges.

-    <title>Submitting a Change to the Yocto Project</title>
-
-    <para>
-        Contributions to the Yocto Project and OpenEmbedded are very welcome.
-        Because the system is extremely configurable and flexible, we recognize
-        that developers will want to extend, configure or optimize it for
-        their specific uses.

-        The Yocto Project uses a mailing list and a patch-based workflow
-        that is similar to the Linux kernel but contains important
-        differences.
-        In general, a mailing list exists through which you can submit
-        patches.
-        You should send patches to the appropriate mailing list so that they
-        can be reviewed and merged by the appropriate maintainer.
-        The specific mailing list you need to use depends on the
-        location of the code you are changing.
-        Each component (e.g. layer) should have a
-        <filename>README</filename> file that indicates where to send
-        the changes and which process to follow.
-    </para>
-
-    <para>
-        You can send the patch to the mailing list using whichever approach
-        you feel comfortable with to generate the patch.
-        Once sent, the patch is usually reviewed by the community at large.
-        If somebody has concerns with the patch, they will usually voice
-        their concern over the mailing list.
-        If a patch does not receive any negative reviews, the maintainer of
-        the affected layer typically takes the patch, tests it, and then
-        based on successful testing, merges the patch.

-        The "poky" repository, which is the Yocto Project's reference build
-        environment, is a hybrid repository that contains several
-        individual pieces (e.g. BitBake, Metadata, documentation,
-        and so forth) built using the combo-layer tool.
-        The upstream location used for submitting changes varies by

-        general mailing list.
-        <note>
-            Sometimes a layer's documentation specifies to use a
-            particular mailing list.
-            If so, use that list.
-        </note>
-        For additional recipes that do not fit into the core Metadata, you
-        should determine which layer the recipe should go into and submit
-        the change in the manner recommended by the documentation (e.g.
-        the <filename>README</filename> file) supplied with the layer.

-        You can also push a change upstream and request a maintainer to
-        pull the change into the component's upstream repository.
-        You do this by pushing to a contribution repository that is upstream.

-        </itemizedlist>
-        Maintainers use these branches to test submissions prior to merging
-        patches.
-        Thus, you can get an idea of the status of a patch based on
-        whether the patch has been merged into one of these branches.
-        <note>
-            This system is imperfect and changes can sometimes get lost in the
-            flow.
-            Asking about the status of a patch or change is reasonable if the
-            change has been idle for a while with no feedback.
-            The Yocto Project does have plans to use
-            <ulink url='https://en.wikipedia.org/wiki/Patchwork_(software)'>Patchwork</ulink>

-
-                    <para>The Yocto Project provides two scripts that

-                    These scripts are <filename>create-pull-request</filename>
-                    and <filename>send-pull-request</filename>.
-                    You can find these scripts in the

-

-                    The maintainer that receives your patches either directly

-                    Using these scripts is the preferred method for sending

-
-                    <para>First, create the pull request.
-                    For example, the following command runs the script,
-                    specifies the upstream repository in the contrib directory
-                    into which you pushed the change, and provides a subject
-                    line in the created patch files:

-     $ ~/poky/scripts/create-pull-request -u meta-intel-contrib -s "Updated Manual Section Reference in README"

-                    Running this script forms

-                    in the current directory.
-                    One of the patch files is a cover letter.</para>
-
-                    <para>Before running the

-                    your change.
-                    After editing the cover letter, send the pull request.
-                    For example, the following command runs the script and
-                    specifies the patch directory and email address.
-                    In this example, the email address is a mailing list:

-    <para>
-        Build time can be an issue.
-        By default, the build system uses simple controls to try and maximize
-        build efficiency.
-        In general, the default settings for all the following variables
-        result in the most efficient build times when dealing with single
-        socket systems (i.e. a single CPU).
-        If you have multiple CPUs, you might try increasing the default
-        values to gain more speed.
-        See the descriptions in the glossary for each variable for more
-        information:

-        As mentioned, these variables all scale to the number of processor

-                Changing this interval from the five second default to
-                something longer increases the risk of data loss but decreases

-                faster, at the expense of being easily able to dive into the

-                rather than delete files due to the linear nature of
-                partitions.
-                This, of course, assumes you structure the disk partitions and

-   Generic XHTML / DocBook XHTML CSS Stylesheet.
-
-   Browser wrangling and typographic design by
-      Oyvind Kolas / pippin@gimp.org
-
-   Customised for Poky by
-      Matthew Allum / mallum@o-hand.com
-
-   Thanks to:
-     Liam R. E. Quin
-     William Skaggs
-     Jakub Steiner
-
-   Structure
-   ---------
-
-   The stylesheet is divided into the following sections:
-
-       Positioning
-          Margins, paddings, width, font-size, clearing.
-       Decorations
-          Borders, style
-       Colors
-          Colors
-       Graphics
-          Graphical backgrounds
-       Nasty IE tweaks
-          Workarounds needed to make it work in internet explorer,
-          currently makes the stylesheet non validating, but up until
-          this point it is validating.
-       Mozilla extensions
-          Transparency for footer
-	  Rounded corners on boxes
