A patch for the config file is also necessary because the include directory
path was being hardcoded in the generated file, which caused problems for cross
compilation. That patch has already been applied on upstream but for a newer
version, so we're backporting it here.

Apparently, the Kinetic release for this package is supposed to work fine with
indigo distribution. That could be tried later, so that we can get rid of the
local patch.

python-rosdistro: add missing lib rosep2 depends on

Update README.md to reflect roswtf's needs.

meta-ros is supposed to be used for building a custom distribution
which isn't derived from any of the OSs known to the rospkg.os_detect
module.

python-rosdep still depends on python-rosdistro in ROS Indigo.

This dependency needs to be dropped after updating the meta
layer to Kinetic.

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.

roswtf reports that

python-imaging: removing recipe maintained in meta-python

Due to the update to 1.8.0, the upstream-accepted patch is not
anymore needed to be applied.

Compiling libflann 1.8.4 with gcc6 fails with:

This issue has been already addressed in the latest version 1.9.1,
hence the commit simply updates the recipe to the version 1.9.1,
which is available on github.

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.
