This patch fixes the continuous integration test by dropping
the sound-play recipe from ros-world, as it would fail with
the master branches (addresses issue #388).

https://github.com/bmwcarit/meta-ros/issues/388

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.

Due to the update, imu-pipeline contains now two ROS packages and
requires patching to build if CATKIN_ENABLE_TESTING is not enabled.

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].

After running oe-stylize.py on all recipes in recipes-ros, this
commit improves the formatting of some recipes.

To achieve this, I executed these commands in recipes-ros:
find . -name *.bb | sed 's#\(.*\)#./oe-stylize.py \1 > \1_sanitized#' | sh
find . -name *.bb | sed 's#\(.*\)#diff -Naur \1 \1_sanitized#' | sh > diffs

Then, I manually inspected the diffs file, and improved the
recipes.

For the DESCRIPTION line in the addressed recipes, the line width
of 100 characters was chosen, as the LIC_FILES_CHKSUM line and
SRC_URI line usually are also around about 100 characters long.
Hence, choosing a shorter line width, e.g. 80 characters, would
have only created more line breaks, but not reduced the need to
use a file viewer with which 100 characters line width can be
displayed. For the github file and diff viewer and most editors
on reasonably-sized screens, 100 character line width is no
problem.
