This commit contain modifications that allow ocropy to be installed
in erp5. The addition of the extra-ld-path variable in the python
part is needed for python to use the right libstdc++ for scipy.

A empty variable extra-ld-path have been created so that software
recipes can add any library they need inside python

Those are needed explicitly when matplotlib is run during the build.

This commit add component needed for Optical Character Recognition:
Ocropy, and the patch that need to be applied to make it work with erp5.

The Ocropy egg on Pypi is empty, so this component have to be built from
source. The default neural network model is downloaded from the author
website and installed in python2.7/share/ocropus.

The patch modify how the setup works to allow the C functions in
native.py to be compiled during setup (removing the need to make zope
use gcc) and provide a way to specify the model path for Ocropy.
The patched setup now need to call some modules from different eggs,
whose path needs to be put into sys.path before it can be run.

More models are available here:

  Include report for apache status (see mod_status on apache documentation)
  Include report to traffic server to produce a summary on cache
  Update report for ats for run only once an hour

  It is protected with monitor password.

also install logrotate binary under ${logrotate:location}/sbin instead
of ${logrotate:location}/usr/sbin, still keeping the backward compatibility.

This fixes a regression introduced in
commit aa5aa9e8.

plugin-load loads plugins in the given order and stops (without exiting)
on the first one that is missing. ha_rocksdb must be listed last because it's
only there when using experimental MariaDB 10.2

This reverts commit 6902a67f.
