Fixing naming space problems.

Fix naming space problems.

 * Do not manually define PKGBASE
 * Do not use meta-pkgs/ros-base/Makefile.common, this package is not ros so
   it's useless.
 * Add required dependencies on devel/ros-xacro, interfaces/ros-control-msgs
   and talos-ros-control
 * Let `make mdi` fix distinfo with the correct distfile name

Add *Config.cmake files to the SYSTEM_SEARCH variable, so that
mk/sysdep/cmake.mk automatically computes the cmake *_DIR variables for
packages using this dependency.

Bump PKGREVISION

Setting CMAKE_PREFIX_PATH is useless. Since each dependency may be located in
its own path, one must pass to cmake the proper _DIR variables.

This is handled automatically by mk/sysdep/cmake.mk when a dependency
SYSTEM_SEARCH variable lists the *Config.cmake files whose path must be fed to
cmake.

SYSTEM_SEARCH should hold the *Config.cmake files so that mk/sysdep/cmake.mk
automatically add *_DIR variable based on the resolved dependency paths.

Bump PKGREVISION

Fix namespace issues in talos_controller_manager_tests

roscpp is in ros-comm not in roscpp-core

rqt_talos_controller_manager: Fix plugins information
talos_controller_manager_tests: Fix python mdule naming scheme

Update this dependency to ros-geometry2, the former is deprecated.
While here, sort dependencies.

Bump PKGREVISION

Some packages require at least this version

Fix namespace problems in : talos_controller_manager_tests,
rqt_talos_controller_manager, talos_controller_manager_msgs

Fix useless mapping of frame names.

Remove config.h from PLIST

Fix install procedures + naming references.

Fix wrong references to plugin namespace.
