[wip/mrpt] Upgrade to 1.2.2

From the Changelog

***** Version 1.2.2: Released 12-SEP-2014 *****
    * Changes in apps:
          o SceneViewer3D:
                # New menu "File" -> "Import" -> "3D model" which supports many
                  standard formats (via mrpt::opengl::CAssimpModel)
    * New classes:
          o [mrpt-hwdrivers]
                # mrpt::hwdrivers::CRoboPeakLidar to interface Robo Peak LIDAR
                  scanners.
          o [mrpt-opengl]
                # mrpt::opengl::CAssimpModel for rendering complex 3D models
                  (many supported formats) in OpenGL scenes.
    * Changes in classes:
          o Consistency in all "laser scan" classes: angular increments between
            rays are now FOV/(N-1) instead of FOV/N.
          o [mrpt-base]
                # New method mrpt::utils::CImage::loadTGA()
                # IMPORTANT: Changed behavior of CSerializable/CObject macros
                  (see bugfix below), introducing the new macros
                  DEFINE_SERIALIZABLE_POST_*. May require changes in user code
                  if serializable classes are defined:
                      # Previous version:
                        DEFINE_SERIALIZABLE_PRE_*(...)
                        class XXX {
                        DEFINE_SERIALIZABLE(XXX)
                        };
                      # Must be changed in this version to:
                        DEFINE_SERIALIZABLE_PRE_*(...)
                        class XXX {
                        DEFINE_SERIALIZABLE(XXX)
                        };
                        DEFINE_SERIALIZABLE_POST_*(...)
          o [mrpt-hwdrivers]
                # Bumblebee2 Linux support in mrpt::hwdrivers::
                  CImageGrabber_FlyCapture2 via Triclops (by Jesus Briales)
          o [mrpt-maps]
                # New method mrpt::slam::COccupancyGridMap2D::getRawMap()
                # New method mrpt::slam::CColouredPointsMap::
                  getPCLPointCloudXYZRGB()
          o [mrpt-opengl]
                # mrpt::opengl::CMyGLCanvasBase (affects all 3D rendering
                  classes): better handling of internal timers for smoother
                  updates while rendering in multithreading apps.
          o [mrpt-srba]
                # New method to recover the global coordinates graph-slam
                  problem for a RBA map: mrpt::srba::RbaEngine::
                  get_global_graphslam_problem() (see example [MRPT]-
                  examples\srba-tutorials\tutorial-srba-how-to-recover-global-
                  map.cpp)
    * BUG FIXES:
          o mrpt::utils::CImage constructor from a matrix crashed.
          o Unit tests: Named semaphores are not tested anymore if it's
            detected that the kernel version doesn't support them (Fix Debian
            758725).
          o mrpt::synch::CSemaphore [Linux]: didn't call sem_unlink().
          o mrpt::gui::CDisplayWindow3D didn't implement get/set FOV.
          o Valgrind: Fixed potential unaligned memory access warning in point
            clouds.
          o Fix build error with AppleClang 5.1 (Closes #71).
          o mrpt::utils::CClientTCPSocket: Use a connection success check that
            works on all platforms
          o Important bug fixed regarding a missing dynamic_cast<> in smart
            pointers casting. See above possible implications in user code.
            properly (Patch by Joe Burmeister).
===============================================================================
***** Version 1.2.1: Released 10-JUL-2014 *****
    * Changes in classes:
          o [mrpt-base]
                # All points and poses now have a method setToNaN(), e.g.
                  mrpt::poses::CPose3D::setToNaN()
          o [mrpt-hwdrivers]
                # mrpt::hwdrivers::COpenNI2Sensor now has better support for
                  opening several RGBD cameras (by Kenzaburo Miyawaki &amp;
                  Eduardo Fernandez)
    * Build system:
          o Fix compilation of SRBA with DEBUG_GARBAGE_FILL_ALL_NUMS=1
          o Fix de-serialization error in mrpt::reactivenav::CLogFileRecord
            (and new unit tests added to avoid regressions).
          o Several Debian bugs closed (see packaging/debian/changelog),
            including build errors in uncommon platforms (MIPS, kFreeBSD, etc.)
===============================================================================
***** Version 1.2.0: Released 25-JUN-2014 *****
    * Most important changes:
          o Public header files (.h) have undergone a serious refactoring to
            minimize unnecesary dependencies and reduce compile time and memory
            as much as possible. As a side effect, user code might need to add
            new #include<> lines. This change justifies the new minor version
            series 1.2.X.
          o MRPT now cleanly builds in clang and OSX.
          o Support for new camera drivers (OpenNI2, DUO3D).
          o Many bug fixes.
    * Detailed list of changes:
          o Changes in apps:
                # rawlog-edit:
                      # New operations: &ndash;export-odometry-txt,
                        &ndash;recalc-odometry
                      # New flag: &ndash;rectify-centers-coincide
          o New examples:
                # kitti_dataset2rawlog
          o New classes:
                # [mrpt-base]
                      # mrpt::math::ContainerType<CONTAINER>::element_t to
                        allow handling either Eigen or STL containers
                        seamlessly.
                      # mrpt::utils::CConfigFilePrefixer
                # [mrpt-hwdrivers]
                      # mrpt::hwdrivers::COpenNI2Sensor: Interface to OpenNI2
                        cameras, capable of reading from an array of OpenNI2
                        RGBD cameras (By Eduardo Fernandez)
                      # mrpt::hwdrivers::CDUO3DCamera: Interface to DUO3D
                        cameras (By Francisco Angel Moreno)
                      # mrpt::hwdrivers::CGPS_NTRIP: A combination of GPS
                        receiver + NTRIP receiver capable of submitting GGA
                        frames to enable RTCM 3.0
                # [mrpt-obs]
                      # mrpt::slam::CObservation6DFeatures
          o Changes in classes:
                # [mrpt-base]
                      # Robust kernel templates moved from mrpt::vision to
                        mrpt::math. See mrpt::math::RobustKernel<>. Added unit
                        tests for robust kernels.
                      # CPose3D has new SE(3) methods: mrpt::poses::CPose3D::
                        jacob_dexpeD_de(), mrpt::poses::CPose3D::
                        jacob_dAexpeD_de()
                      # More efficient mrpt::utils::OctetVectorToObject()
                        (avoid memory copy).
                      # Fixed const-correctness of mrpt::utils::CImage::
                        forceLoad() and mrpt::utils::CImage::unload()
                # [mrpt-hwdrivers]
                      # mrpt::hwdrivers::CCameraSensor: Added a hook for user
                        code to run before saving external image files: mrpt::
                        hwdrivers::CCameraSensor::addPreSaveHook()
                      # mrpt::hwdrivers::CNationalInstrumentsDAQ now supports
                        analog and digital outputs.
                      # New method mrpt::hwdrivers::CNTRIPClient::
                        sendBackToServer()
                # [mrpt-srba]
                      # Now also implements SE(3) relative graph-slam.
                # [mrpt-vision]
                      # mrpt::vision::checkerBoardStereoCalibration: More
                        robust handling of stereo calibration patterns. OpenCV
                        sometimes detects corners in the wrong order between
                        (left/right) images, so we detect the situation and fix
                        it.
                      # mrpt::vision::findMultipleChessboardsCorners():
                            # Now enforces a consistent counterclockwise XYZ
                              coordinate frame at each detected chessboard.
                            # Much more robust in distingishing quads of
                              different sizes.
          o Build system / public API:
                # Fixes to build in OS X - Patch by Randolph Voorhies.
                # Removed most "using namespace" from public headers, as good
                  practice.
                # Refactoring of MRPT headers.
                      # <mrpt/utils/stl_extensions.h> has been split into:
                            # <mrpt/utils/stl_serialization.h>
                            # <mrpt/utils/circular_buffer.h>
                            # <mrpt/utils/list_searchable.h>
                            # <mrpt/utils/bimap.h>
                            # <mrpt/utils/map_as_vector.h>
                            # <mrpt/utils/traits_map.h>
                            # <mrpt/utils/stl_serialization.h>
                            # <mrpt/utils/printf_vector.h>
                            # <mrpt/utils/stl_containers_utils.h>
                            # <mrpt/utils/ci_less.h>
                # Deleted methods and functions:
                      # mrpt::system::breakpoint()
                      # mrpt::vector_float is now mrpt::math::CVectorFloat,
                        mrpt::vector_double is mrpt::math::CVectorDouble, for
                        name consistency. Also, using Eigen::VectorXf is
                        preferred for new code.
                      # mrpt::CImage::rectifyImage() with parameters as
                        separate vectors.
                      # mrpt::slam::CPointsMap::getPoint() with mrpt::poses::
                        CPoint3D arguments.
                      # mrpt::vision::correctDistortion() -> use CImage method
                        instead
                      # All previous deprecated functions.
                # Embedded Eigen updated to version 3.2.1 (commit) (commit)
          o BUG FIXES:
                # RawlogViewer app: Fixed abort while converting SF->obs.only
                  datasets when there is no odometry.
                # mrpt::slam::CSensoryFrame: The cached point map is now
                  invalidated with any change to the list of observations so
                  it's rebuild upon next call.
                # New implementation of mrpt::synch::CSemaphore avoids crashes
                  in OS X - by Randolph Voorhies.
                # mrpt::opengl::CArrow was always drawn of normalized length.
                # FlyCapture2 monocular &amp; stereo cameras could return an
                  incorrect timestamp (only in Linux?).
                # mrpt::system::createDirectory() returned false (error) when
                  the directory already existed.
                # mrpt::vision::CStereoRectifyMap::rectify() didn't update the
                  left &amp; right camera poses inside mrpt::slam::
                  CObservationStereoImages objects while rectifying.
                # RawLogViewer: Operation "convert to SF format" didn't take
                  into account odometry observations.
                # Fix build errors with GCC 4.9
                # Fix crash of mrpt::hwdrivers::CIMUXSens_MT4's destructor when
                  it fails to scan and open a device.
                # Fix potential crash in mrpt::slam::
                  data_association_full_covariance with JCBB when no
                  individually compatible matching exists (commit)
