Rework RLOF by using HAL universal instructions

* * distinguish between SSE2 and SSE 4.1 support
* SSE2 now implements no paralellized _blendv functiona and allows to compile with SSE2 instructions

* * add interface function do enable disable M-estimator framework
* bugfix blendv functions

* * make use of _mm_store and _mm_load functions in blendv_ps and blendv_epi function to fix compiler error

* * implement substitute of _mm_cvtepi8_epi16 and _mm_cvtepi16_epi32 when compiling with less than SSE 4.1 support

* * implement substitute of _mm_abs_epi16 when compiling with less than SSE 3 support

* * move _mm_abs_epi16 to SSE4 req.

* * add HAL intrinsic functions for RLOF ICA
* first tests are OK

* * HAL intrinsic functions -> RLOF ICA is ready now

* * add HAL functions for RLOF illumination model

* * add HAL for PLK ILL

* * add HAL functions for plk ica

* * commit HAL functions for beplk ica

* * add HAL functions for berlof ica

* * add HAL functions for BEPLK ILL

* *remove unused #ifdef

* * remove white spaces and unused variables

* * remove not used variables

* + remove get4BitMask function which contained pure SEE instructions

* * remove buffIdx which has not been used but initialized

* * fix replacement of #ifdef CV_SIMD128 with #if CV_SIMD128
* rename useMEstimator to setUseMEstimator

* *remove whitespace

* * remove unused variable abss

* * remove unused value

* * rename W_BITS1 to W_BITS since they contain same value

Add robust local optical flow (RLOF) implementations (#1940)

* Add robust local optical flow (RLOF) implementations which is an improved pyramidal iterative Lucas-Kanade approach. This implementations contains interfaces for sparse optical flow for feature tracking and dense optical flow based on sparse-to-dense interpolation schemes.
Add performance and accuracy tests have been implementation as well as documentation with the related publications

* - exchange tabs with spaces
- fix optflow.bib indentation
- remove optflow_o.hpp
- change RLOFOpticalFlowParameter interfaces to Ptr<RLOFOpticalFlowParameter>
to remove error on building. Fix warnings

* introducing precompiler flag RLOD_SSE

* remove header that could not be found

* remove whitespaces
fix perf and accuracy tests

* remove x86intrin.h header

* fix ios and arm by removing last sse commands

* fix warnings for windows compilation

* fix documentation RLOFOpticalFlowParameter

* integrate cast to remove last warnings

* * add create method and function inferfaces to RLOFOpticalFlowParamter to enable python wrapper interfaces

* white space fixes / coding style

* fix perf test

* other changes: precomp.hpp / static

* use Matx44f and Vec4f instead of Mat

* normSigmas into constants

* replace ceil() calls

* maximum level is set to 5 so that it is similar value used in the papers

* implement paralellized horizontal cross segmentation as used in Geistert2016

* drop dead code

* Avoid using "data" and "step" calculations. Use .ptr<mat_type>(row, col) instead.

* Avoid using "data" and "step" calculations. Use .ptr<mat_type>(row, col) instead.

* bugfix on BEPLK with ica and adapt the accuracy tests

* more 'static' functions

* bugfix after changing ptr + step to .ptr(y,x) calls by adjusting ROI of
prevImage, currImage and derivI as well as changing the offset of the
points in the invoker classes.

* add some static_cast to avoid warning

* remove 50 grid size sample from perf test. This grid size is to sparse
for the epic interpolation

* remove notSameColor function since it is not used anymore
