Fixing 6 instances of MISRA rules being broken

Fix vector initialization in NormalEstimationOMP

Relies on #3615 to do the toggling

Add a toggle option to grabber

Easy way to toggle streaming devices. Works with concurrent controllers (dual `isRunning`)

Remove dublicate /bigobj

Using prefix ++/-- operators for non-primitive types

Fixes #3622 (regression)

Remove unneeded variables

Add Mojave build to CI.

Fix compile issue in people_app.cpp as shared_ptr was ambiguous.

It was ambiguous because of using namespace std and pcl at same time. To prevent such issue `using namespace` is now removed.

Fix indexing in IntegralImageNormalEstimation #3573

The vectors nn_indices and nn_dists in
NormalEstimationOMP::computeFeatures must be initialized to the correct
size. They are initialized at the beginning of the function but the
OpenMP parallel for loop basically generates a new pair of vectors for
each thread. These vectors are initialized with the default constructor
which means that they have zero size.
To fix this I used 'firstprivate' for the vectors instead of 'private'
this causes that the copy constructor is called instead of the default
constructor.

[features] Refactoring and proper Eigen usage (5/N)

Make ctors more uniform for PCL Point Types

Explicit substraction instead of typo wrt '->'

Removing accidentally shadowing of larger scope variable

Added bigobj with add_compile_options.

Add a test case where the problem from #3573 of the
IntegralImageNormalEstimation is tested.

When the border handling of the IntegralImageNormalEstimation is set to
BORDER_POLICY_IGNORE and you use indices to only compute a subset of the
normals the right border wasn't handled correctly because the wrong
coordinate was used for the check.
