352510cc19 core: fix ARM intrinsincs 
'0' is specific case (make no sence as a standalone operation),
but it can be useful in template-based programming.

6f675ae75b Merge pull request #11304 from kinchungwong:issue_11242_intrin_cv34x_nocpp11 
* Issue 11242 intrinsics v_extract, v_rotate improvement, branch 3.4, without C++11 (remove type restrictions for SSE2, use PALIGNR on SSSE3, compile to no-op when imm is 0 or nlanes).

* fix whitespace

* Fix #11242 (NEON intrinsics v_rotate...) branch 3.4
Separate macro expansion OPENCV_HAL_IMPL_NEON_SHIFT_OP for bitwise shifts for integers, from macro expansion OPENCV_HAL_IMPL_NEON_ROTATE for lane rotations. Bitwise shifts do not apply to floats, but lane-rotations can apply to both.

* fix whitespace

* Fix #11242 compile error (VSX intrinsics v_rotate(a)) branch 3.4 no-c++11

7be0c78533 Merge pull request #10589 from patrikhuber:patch-1 
* Make <array> #ifdef true for MSVC

I think MSVC had `std::array` for quite a while (possibly going back as far as VS 2012, but it's definitely there in 2015 and 2017. So I think `_MSC_VER` `1900` is a safe bet. Probably `1800` and maybe even `1700` could work as well but I can't test that locally.

* fix test

46a668c565 Add multi-channel mask support to mean, meanStdDev and setTo 
This adds the possibility to use multi-channel masks for the functions
cv::mean, cv::meanStdDev and the method Mat::setTo. The tests have now a
probability to use multi-channel masks for operations that support them.
This also includes Mat::copyTo, which supported multi-channel masks
before, but there was no test confirming this.

eb04b2bfa9 Added N-dim submat selection with vectors 
Currently, to select a submatrix of a N-dimensional matrix, it requires
two lines of code while only one line of code is required if using a 2D
array.

I added functionality to be able to select an N-dim submatrix using a
vector list instead of a Range pointer. This allows initializer lists to
be used for a one-line selection.

ddf0554fff Use colon in "%YAML:1.0" directive when persisting to YAML-files 
In YAML 1.0 the colon is mandatory. See http://yaml.org/spec/1.0/#id2558635.

This also allows prior releases to read YAML files created with the current version.
