The poco recipe is in meta-oe now for quite some time and is
actively updated and maintained there. Also, meta-ros with its
recent changes, especially the changes due to recipe-specific
sysroots, is unlikely to build with older versions of meta-oe.
Hence, this commit drops the poco recipe in meta-ros for good.

As the main repository for the librealsense recipe now contains
fixes required for linking catkin-based packages against it
we can stop maintaining our own version of librealsense recipe.

Also this patch adapts realsense-camera recipe to link against
the non-catkin version of librealsense.

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.
