This commit includes further changes to build rospack-native.

python-nose: replacing duplicate recipe that is in meta-oe by a bbappend file to have a native recipe (resolves #66)

To compile nodelet-topic-tools, we must provide a working
dynamic-reconfigure in the native sysroot. This requires
some adjustments to the native versions of the required
python modules.

In particular, the following tasks ran successfully for this
commit:

This command tests compiling rospack-native:
rm bitbake.lock cache/ sstate-cache/ tmp-eglibc/ -rf && bitbake rospack-native

This command tests compiling roslib-native:
rm bitbake.lock cache/ sstate-cache/ tmp-eglibc/ -rf && bitbake roslib-native

As nodelet-topic-tools uses rospack-native and roslib-native to
some extent (dependency: rospack-native -> roslib-native ->
dynamic-reconfigure-native -> nodelet-topic-tools), this command
tests running rospack-native and roslib-native:
rm bitbake.lock cache/ sstate-cache/ tmp-eglibc/ -rf && bitbake nodelet-topic-tools

This command tests compiling rospack and roslib:
rm bitbake.lock cache/ sstate-cache/ tmp-eglibc/ -rf && bitbake rospack
rm bitbake.lock cache/ sstate-cache/ tmp-eglibc/ -rf && bitbake roslib

All these command run with this commit without errors, and
future commits to these files should keep them run without
errors or justify modifications with better tests.

A minor open issue related to rospack is issue #116
(cf. https://github.com/bmwcarit/meta-ros/issues/116).

This commit incorporates feedback from Stefan Herbrechtsmeier.

This commit adds the yaml-cpp recipe from the repository at
https://github.com/kartikmohta/meta-km. The file is licensed
with the MIT license
(cf. https://github.com/kartikmohta/meta-km/blob/master/LICENSE).

The original recipe can be found at
https://github.com/kartikmohta/meta-km/blob/master/recipes-devtools/yaml-cpp/yaml-cpp_0.3.0.bb

The README file acknowledges Kartik Mohta's contribution and names
him as a contributor.

The native log4cxx recipe is required for the recipe
dynamic-reconfigure-native.

The python-rospkg-native rdepends on python-xml-native, and
python-native provides this without any further ado.

The current catkin requires catkin_pkg >= 0.1.12 as indicated in
https://github.com/ros/catkin/blob/groovy-devel/package.xml

.

using BBCLASSEXTEND = "native" and removing the separate native package files (thanks to Stefan Herbrechtsmeier for this hint)

improving dependencies in the python recipes; simplifying core-image-ros after dependencies are improved

tried to add python-vcstools via dependency in python-rosinstall but it does not do and then added it the core-image instead; tuned layout and order in core-image

adding the recipe python-vcstools, as now that the python recipes do not use setuptools to get all the dependencies write we need further recipes

adding the setuptools class from openembedded classic; adjusting the packages; adding legal statement
