Transition to standard smart pointers, part 13

[SergioRAgostinho]

Partially addresses #2792.

All modules are compiling in my local environment. There were a couple of replacements which I was not able to perform. I battled a little with the compiler but eventually gave up.

I had troubles performing the following replacement

pcl/gpu/segmentation/include/pcl/gpu/segmentation/gpu_extract_labeled_clusters.h

Lines 53 to 58 in 3e04ea7

	extractLabeledEuclideanClusters (const boost::shared_ptr<pcl::PointCloud<PointT> > &host_cloud_,
	const pcl::gpu::Octree::Ptr &tree,
	float tolerance,
	std::vector<PointIndices> &clusters,
	unsigned int min_pts_per_cluster,
	unsigned int max_pts_per_cluster);

It is causing an unintentional SFINAE and I can't figure out exactly how to overcome it. Give it a try if you can.

I think the only solution here is to specify the point type explicitly at the calling site, i.e. extractLabeledEuclideanClusters<pcl::PointXYZ>(pc, ...).

Thank you for the tip. The compiler messages pointed me completely in the wrong direction.
