Rename old ROS components (sensor_msgs/*)

std_msgs::Header -> pcl::PCLHeader
sensor_msgs::Image -> pcl::PCLImage
sensor_msgs::PointCloud2 -> pcl::PCLPointCloud2
sensor_msgs::PointField -> pcl::PCLPointField
Took out all USE_ROS references
Move conversions into common/pcl

fromROSMsg -> fromPCLPointCloud2
toROSMsg -> toPCLPointCloud2
Remove pcl_2d and dependent files
Remove pcl_cuda
Remove pcl_gpu
Remove CUDA related cmake stuff
Remove pcl_ml and dependent files
Remove pcl_simulation
Remove pcl_stereo
Remove 3rdparty stuff
Remove Brisk keypoints and features because there is no non SSE4 version
Fixed install path for conversions.h and register_point_struct.h
Merge remote-tracking branch 'origin/master' into next_new
