* Fixed OCL implementation of pyrlk If prevPts size is (N, 1) (which is a default layout for converting `vector<Point2f>` to `UMat`) the `prevPts.cols == 1` and optical flow will be calculated for the first point only. Getting `prevPts.total()` as in line 1048 is the correct way to get points count. * fixed compilation warning (size_t to int) Signed-off-by: NSergey Krivohatskiy <s.krivohatskiy@gmail.com>

* fix find zlib.so instead of zlib.a when NDK >= 19 On Android platform, `libopencv_imgcodecs.a` is built, expected to depend on `libz.so`. However, since Android NDK r19, NDK's `libz.a` is found instead of `libz.so`, leading to link error (not found libz.a) on machines without same NDK version & direcotry. Since Android NDK-r19, toolchain pieces are installed to `$NDK/toolchains/llvm/prebuilt/<host-tag>/...`, including `libz.so`. Also installed to old paths (`<NDK>/platforms` and `<NDK>/sysroot`) in NDK r19, r20, r21, but since NDK 22, old paths are removed. - https://github.com/android/ndk/wiki/Changelog-r19 - https://github.com/android/ndk/wiki/Changelog-r22 With this commit, `libz.so` can be correctly found in NDK<19 and NDK>=19. `ZLIB_LIBRARIES` is also simplified as `z`, by appending match (regex) patterns for new toolchain installation directory's libz.so's paths. * simplify libz.so match pattern for abbreviation

* fix core module android arm64 build * fix core module android build when neon is off When building for Android ARM platform, cmake with `-D CV_DISABLE_OPTIMIZATION=ON`, the expected behavior is not using ARM NEON, using naive computation instead. This commit fix the un-expected compile error for neon intrinsincs.

Previous link dependency: imgcodecs --> zlib --> libpng this can generate imgcodecs shared lib, until Visual Studio integrated with vcpkg, which will additionally specify LIBPATH, pointing to vcpkg installed zlib (if any), which links the wrong zlib. Fixed link dependency: imgcodecs --> libpng --> zlib in this fixed case, symbols in zlib referenced in libpng will be found in the build-from-source static zlib, instead of the vcpkg one. related discussion: - https://github.com/microsoft/vcpkg/issues/16165 - https://github.com/opencv/opencv/issues/17051 - https://github.com/opencv/opencv/issues/10576 MSVC linking order reference pages: - https://docs.microsoft.com/en-us/cpp/build/reference/link-input-files?view=msvc-160 for link order - https://docs.microsoft.com/en-us/cpp/build/reference/linking?view=msvc-160 LIB environment variable, for library file searching - https://docs.microsoft.com/en-us/cpp/build/reference/libpath-additional-libpath?view=msvc-160 LIBPATH option, for library file searching

* [hal][neon] Optimize the v_dotprod_fast intrinsics for aarch64. On Armv8 in AArch64 execution mode, we can skip the sequence v<op>_<ty>(vget_high_<ty>(x), vget_high_<ty>(y)) in favour of v<op>_high_<ty>(x, y) This has better changes for recent compilers to use less data movement operations and better register allocation. See for example: https://godbolt.org/z/bPq7vd * [hal][neon] Fix build failure on armv7. * [hal][neon] Address review comments in PR. PR: https://github.com/opencv/opencv/pull/19486 * [hal][neon] Define macro to check for the AArch64 execution state of Armv8. * [hal][neon] Fix macro definition for AArch64. The fix is needed to prevent warnings when building for Armv7.
