The patch to dwa_local_planner has been incorporated in version
1.12.3, and hence is removed here.

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 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.

The previously applied patch has been included in 1.11.8 and is
removed from the recipe and this repository. Furthermore, the
LIC_FILES_CHKSUMs are adjusted to changes in the package.xml files.

The patches provided upstream are part of 1.11.6 and are removed.

This commit includes all navigation packages except robot_pose_ekf.
The robot_pose_ekf requires bfl, which we could not provide yet.
