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.

The meta-oe provides since commit 8700ba38@openembedded/meta-openembedded
(commit date: 2016-01-14) [1] a recipe for the POCO C++ Library.
Consequently, this commit removes the libpoco recipe in the
meta-ros layer.

As meta-ros already depends on the meta-oe layer, the poco
recipe is available in release version since 2016-01-14,
and the poco recipe in meta-ros is redundant for these versions.
However, this commit still provides the currently latest poco
recipe [2] for users that are not using a recent version of the
meta-oe layer.

The Openembedded Layer Index [1] shows that python-six in
version 1.10.0 is already provided in the openembedded-core layer
and in the meta-python layer, so there is no need for a third copy
of the python-six recipe in meta-ros.

The recipe python-six is provided since commit a36869c7 in the
meta-openembedded repository (commit date: 2015-04-13), and
is provided since commit 9979e35f in the openembedded-core
repository (commit date: 2016-07-20).

In my opinion, at least the commit a36869c7 is far enough in the
past, so that we can safely assume that all new meta-ros use a setup
where python-six is included at least in meta-python.

For users of older versions, we include a remark in the README.md to
allow `git blame` to pinpoint to this commit here.

In the meta-ros commit b6080314 (commit date: 2013-11-17) [1], we
add python-numpy_1.7.0.bbappend to provide python-numpy as native
package, as the version update to cv-bridge 1.10.14 needs that.

Coincidentally, Ross Burton added native support to the
python-numpy recipe in the meta-openembedded commit c13c5f40
(commit date: 2013-11-18) [2]. However, the existing bbappend in
meta-ros was still required for use with releases before commit
c13c5f40.

On 2014-01-14, the python-numpy recipe was moved from meta-oe to
openembedded-core (commit a4415f89 and 9bf355cc [3, 4]).
Now, on 2015-12-16, the python-numpy recipe was updated to 1.10.1
(commit 3c3932f3 [5]), and hence, our version-specific bbappend
file fails to apply.

As the native package addition is now in the recipe for over two
years (commit date: 2013-11-18), and we assume all users to work on
versions where the change has been included, we simply drop our now
superfluous bbappend file.

This commit adds the yaml-cpp recipe from the repository at
https://github.com/kartikmohta/meta-km. The file is licensed
with the MIT license
(cf. https://github.com/kartikmohta/meta-km/blob/master/LICENSE).

The original recipe can be found at
https://github.com/kartikmohta/meta-km/blob/master/recipes-devtools/yaml-cpp/yaml-cpp_0.3.0.bb

The README file acknowledges Kartik Mohta's contribution and names
him as a contributor.

This commit adds the eigen library from Kartik Mohta's OpenEmbedded
layer. Acknowledgements are added in the README file.

This commit moves the description of previous uses in a separate file,
adds the typical information for a README of an OpenEmbedded layer and
describes the usage for the roscore image recipe.

Instead of maintaining a copy of the tinyxml recipe from the meta-oe layer, we
require that the installation also includes the meta-oe layer.
We updated the README accordingly and also updated the description of the
current setup. We also updated and tuned the CONTENT file.

This commit resolves issue #45.
