The catkin package has got a runtime dependency to cmake, make,
gcc and other build utilities. These dependencies, however, are
only needed if it is desired to build with catkin on the target
board. If we do not want to build on the target board, i.e., if
we just want to use ros tools like roslaunch, only a small part
of catkin (i.e., the corresponding python packages) is required
to be deployed on the target board.
Therefore, we introduce a new package called catkin-runtime.
It installs only the python packages that are required for
the ros tools to run. The roslib package now depends on
catkin-runtime (previously: catkin).

I also tried an alternative approach which just modifies catkin.bb:
- add a catkin-runtime package
- move PYTHON_SITEPACKAGES_DIR from FILES_catkin to FILES_CATKIN_RUNTIME
- make catkin_runtime RDEPEND on the python stuff
- make catkin RDEPEND on the cmake, binutils, ..., + catkin-runtime
With this setup, for some reason, bitbake thinks that
catkin-runtime still RDEPENDS on binutils. Therefore, I split up
the catkin recipe into two different recipes. Here, the
RDEPENDS are managed correctly.

If we want to deploy catkin as a build tool on the board, we can
simply add a runtime dependency to catkin. However, this should
not be the default setup.

ROS and catkin packages install their assets to paths prefixed by
ros_prefix. As the recipe was trying to collect the assets for the dev
package in the wrong locations, the dev package was empty.

To address this we use the ros_prefix consistently across the recipe.

This commit further adds a simple fix to the patch for the ros-comm
repository.

Resolves import error in __init__.py files derived from catkin/cmake/templates/__init__.py.in template,
e.g. in tf:
  File "/usr/lib/python2.7/site-packages/tf/__init__.py", line 7, in <module>
    from pkgutil import extend_path
ImportError: No module named pkgutil

The catkin recipe is updated to 0.5.77 to be in line with
https://github.com/ros/rosdistro/blob/ef3a7449d7f7ef6e691a5724ef6c485e75cfd4af/hydro/release.yaml.

The native packages are not required anymore, because the needed
python scripts during compile time are also provided by the
cross-compiled packages and the python scripts are platform
independent. Only the catkin package is provided as native package.

The catkin recipe was updated to 0.5.73 to be in line with
https://github.com/ros/rosdistro/blob/4551e7c32d1b34984410b79bc0ec36afe3d3d245/hydro/release.yaml.
The previously applied patch has been included in 0.5.73 and is
removed from the recipe and this repository.

The native catkin recipe has no runtime dependency on
the native version of packagegroup-core-buildessential.

The catkin scripts require the ast python module, which is shipped
with python-misc.

catkin is a build tool based on cmake and requires the common
build tools to work properly.

The catkin_make command requires a number of python modules.

Catkin require a .catkin file in all CMAKE_PREFIX_PATH to add them
to the CATKIN_WORKSPACES. Remove this requirement as it couldn't
be satisfy when catkin packages are installed into the common usr
prefix. Without this adaption catkin couldn't find all files.

The catkin framework need some modification to support cross compiling
packages via yocto. When we want to upstream patches we need to provide
patches against the current groovy-devel branch. Use this branch as base
for our work to simplify the tests and to unify the developing process
of catkin.

* Use configuration options instead of patches
* Use relative paths in CMake installation files
* Use catkin class

patching catkin to remove assertion for rt-library (this must revisited at some later point again when we have a better understanding of the issue.)

removing alternative recipe for catkin-native because using catkin and BBCLASSEXTEND+=native does the job for now
