Allows to choose orthogonal sub-vectors for LSH without using a static table among LshTable instances

Consistent with the test made in cv::boxFilter, it adjusts the kernel size to the source size only if the border is not BORDER_CONSTANT and if BORDER_ISOLATED is set. Otherwise, the source has to be considered possibly in a larger image (i.e. the source being a ROI) in witch the kernel should apply.

removed invalid condition, it is always false

add missing stream parameter to call_resize_linear_glob

Ticket 3458 (http://code.opencv.org/issues/3458)

reshape input matrix, since the function works with data
as with [N x dims] matrix

Clarify how the mask parameter is set on output and how this is
affected by the flags parameter.

resolves Feature #2942
