roswtf reports uninitialized /etc/ros structure and recommends
to fix the issue by running `rosdep init`. But rosdep throws an
exception when trying to import the missing rosdistro library.

The library is supposed to be dropped in kinetic, but it's still
needed in indigo which the layer is based on at the moment.
So, the patch adds the library to the layer.

On 2016-06-08, the commit 000095f3 [1, 2] added the python-imaging
recipe that was dropped in OpenEmbedded Core in commit b03ebfaee [3]
on 2016-06-02.

Coincidentally, python-imaging was also added in meta-python
on 2016-06-08 [4], and it has been further maintained in that layer [5].

Instead of continuing to maintain the recipe in meta-ros, we decide to
rely on the recipe provided in meta-python, and hence, remove the
recipe in meta-ros.

The Openembedded Layer Index [1] shows that python-six in
version 1.10.0 is already provided in the openembedded-core layer
and in the meta-python layer, so there is no need for a third copy
of the python-six recipe in meta-ros.

The recipe python-six is provided since commit a36869c7 in the
meta-openembedded repository (commit date: 2015-04-13), and
is provided since commit 9979e35f in the openembedded-core
repository (commit date: 2016-07-20).

In my opinion, at least the commit a36869c7 is far enough in the
past, so that we can safely assume that all new meta-ros use a setup
where python-six is included at least in meta-python.

For users of older versions, we include a remark in the README.md to
allow `git blame` to pinpoint to this commit here.

The recent versions of the rosbridge_library package does not depend
on python-pytz anymore. So, this commit removes the dependency in
the recipe file and removes the now unneeded python-pytz recipe.

This commit resolves issue #393.

This commit adds recipes for rosbridge_suite and its dependencies.
Its main content is based on the commits of pull request #364 by
Christoph Schultz.

As maintainer, Lukas Bulwahn just included the contributions
with a proper commit message, added the new packages to the
packagegroup-ros-world, and slightly improved the line breaking.

In the meta-ros commit b6080314 (commit date: 2013-11-17) [1], we
add python-numpy_1.7.0.bbappend to provide python-numpy as native
package, as the version update to cv-bridge 1.10.14 needs that.

Coincidentally, Ross Burton added native support to the
python-numpy recipe in the meta-openembedded commit c13c5f40
(commit date: 2013-11-18) [2]. However, the existing bbappend in
meta-ros was still required for use with releases before commit
c13c5f40.

On 2014-01-14, the python-numpy recipe was moved from meta-oe to
openembedded-core (commit a4415f89 and 9bf355cc [3, 4]).
Now, on 2015-12-16, the python-numpy recipe was updated to 1.10.1
(commit 3c3932f3 [5]), and hence, our version-specific bbappend
file fails to apply.

As the native package addition is now in the recipe for over two
years (commit date: 2013-11-18), and we assume all users to work on
versions where the change has been included, we simply drop our now
superfluous bbappend file.

The resource_retriever package's source was moved into
its own repository, and needs now python-urlgrabber.
Hence, this commit provides the recipe for python-urlgrabber, moves
the resource-retriever to its own location, and updates all other
packages in the robot_model repository.

Due to the recent commit 6eddc9e2@openembedded-core [1], which
updated python-nose from 1.2.1 to 1.3.6, the bbappend for
python-nose 1.2.1 leads to an error during parsing. Instead of
making the bbappend version-independent, this commit simply drops
the bbappend file, as python-nose is provided as native package
already since 78711c88@openembedded-core [2] (since January 2014).

When compiling python-rosdep before python-nose has been built,
'bitbake python-rosdep' fails with:

In a recent commit in the rosdep repository [1], the dependency for
the rosdep setup on python's nose package is added. Hence, we must
also add this dependency in the rosdep recipe, which then resolves
the reported failure.

In the recent commit d4ad95f0 [1], the OpenEmbedded-Core repository
updated python from version 2.7.3 to 2.7.9. To make meta-ros
compatible to the latest commits, the bbappend files are renamed to
be version independent.

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.

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

.
See discussion in #99.
