Scott Little b2286535c9 Update to build tools to support Build layering.
1: Building rpms now produces an rpm.lst file.  This file serves to
list all rpms produced by the build.  A seperate rpm.lst file
is producede for each build type (std, rt, installer). The file is
co-resident with the matching repodata directory.

The rpm.lst files will need to be published by cengn for each layer build.

The download tools in stx-tools will need to find the rpm.lst files
of lower layer builds, and use it to direct the download of rpms
from the lower layer.

2: Building rpms now produces an image.inc file.  This file serves
to list all rpms that the layer recommends be built into an iso.
The file is stored under the $MY_WORKSPACE/<build-type> subdirectory,
although it has identical content for any build-type.

The image.inc file will need to be published by cengn for each layer
build.

The download tools in stx-tools will need to download the per-layer
image.inc files to the $MY_REPO/cgcs-centos-repo/layer_image_inc/
sub-directory, renaming the file in some layer specific way.

The build-iso tool will process any *.inc files found under
$MY_REPO/cgcs-centos-repo/layer_image_inc/ ,
adding those rpms to the iso.

3) Add a mechanism for layer specific mock.cfg prototypes.
This will allow special handling of the real-time (aka 'rt'),
repositories for layer builds that need to do a 'rt' build.

4) Add support for a $MY_REPO/cgcs-centos-repo/rt subdirectory,
a place to build a repo of real-time rpms originating from
lower layer builds.

The download tools in stx-tools will need to populate the new
rt repos.

As of this writing, non-rt rpms remain in $MY_REPO/cgcs-centos-repo/.
i.e. there is not a new $MY_REPO/cgcs-centos-repo/std/ directory.

5) Some changes to make us more flexible about where we find
realease and bsp files.

6) Found that kernel mudules were not reliably building against
the hearnel-headers of our modified kernel.  Found that adding '--update'
to our mock build command was not working.  Does mock expect '--update'
to only be used independently of a build command?  It does work when
used in that manner, so that's what we will do.

7) The build-pkgs, build-srpms, build-rpms family of commands
can take a layer argument and/or will read the LAYER environment
variable.  Current the only use of this variable is to modify
the build-info.  It does NOT limit the compile to packages
for a specific layer.
