Compiler message:
tif_unix.c:170:12: error: call to 'mmap' declared with attribute error:
mmap is not available with _FILE_OFFSET_BITS=64 when using GCC until android-21.
Either raise your minSdkVersion, disable _FILE_OFFSET_BITS=64, or switch to Clang.

  - fix compilation error about "inline"
  - fix linker error about "_TIFF_snprintf_f"

Implementation of bit-exact resize. Internal calls to linear resize updated to use bit-exact version. (#9468)

- 3rdparty/libjasper/jas_getopt.c:129:25: warning: this function declaration is not a prototype [-Wstrict-prototypes]
- clang: warning: optimization flag '-fomit-frame-pointer' is not supported for target 'armv7' [-Wignored-optimization-argument]

clang pretends to be gcc 4.2.0 which means we will
use inline asm for no reason, instead of builtins
on clang when possible.

- Optimizations set change. Now IPP integrations will provide code for SSE42, AVX2 and AVX512 (SKX) CPUs only. For HW below SSE42 IPP code is disabled.
- Performance regressions fixes for IPP code paths;
- cv::boxFilter integration improvement;
- cv::filter2D integration improvement;

- '-fvisibility' flag was updated
- PVAPI library detection was changed

It is configurable via OPENCV_CPUFEATURES_TARGET_NAME variable
