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.

Solves following warning:
QA Issue: roslint requires /bin/bash,
but no providers in its RDEPENDS [file-rdeps]

roscore-default: Removing not supported variable in variable
roscore-default: Adding PATH, LD_LIBRARY_PATH and PYTHONPATH
roscore.service: Using /opt/ros/hydro/bin instead of /usr/bin to launch
roscore

You can now install roslaunch-systemd :

opkg install roslaunch-systemd

and start roscore :

systemctl start roscore

Since version 1.7.15, the bondcpp package needs the cmake_modules
package. The dependency was added with this commit:
https://github.com/ros/bond_core/commit/f4265d6b28f250d95364197f2694653db9618245

This issue was reported by Gauthier Monserand (simkim -at- simkim.net).

The patches in the meta-ros repository have been submitted and
included in 0.7.3 and hence are deleted in this commit.

The patch in the meta-ros repository has been submitted and
included in version 0.7.3 and hence is deleted in this commit.

After updating to 0.3.2, the patch is obsolete, and hence removed.

This commit also adds cmake-modules to the dependencies of
clear-costmap-recovery, while looking into an build issue of the
intermediate version 1.11.12(!) of navigation.

The urdfdom-headers package was removed from packagegroup-ros-world
in #182, because it is an empty package and causes the image
creation to fail (cf. #177).
In commit 9ff8d1f7, urdfdom-headers
was added again while adding new ROS packages to
packagegroup-ros-world. As part of the manual regression testing,
executing 'bitbake packagegroup-ros-world' for the different qemu
architectures, but not building full images, this problem has
slipped through the regression testing the last few months. This
issue was reported on the meta-ros mailing list by Parag
Batavia [1].

In commit 53796fc4, bitbake fails at parsing. It slipped through,
as I did not invoke any testing before submitting 53796fc4. This
commit resolves the obvious shortcoming.

The description is not indented after line breaks. All other
information, i.e., the dependencies and SRCURI, are indented with
four spaces after line breaks. Shell scripts are indented with
multiples of four spaces.

In recipes-ros, I located and checked for tabulators and spacing
with these bash commands:

egrep '^ [^ ]+' . --exclude *.patch -R
egrep '^  [^ ]+' . --exclude *.patch -R
egrep '^   [^ ]+' . --exclude *.patch -R
egrep '^    [ ]+[^ ]+' . --exclude *.patch -R

While going through the recipes and manually improving the layout,
I also adjusted the descriptions to use maximal 100 characters
per line.
