Last changes in test leads to SIGKILL on Android.
SIGKILL is called by out of memory killer.

Use correct integer types for arguments to TIFFGetField to avoid corruption
of values and failed loads of TIFF file when using cv::imread().

Added test where both big and little endian TIFF files are read using imread().

Fixed build of 3rdparty libtiff on big endian hosts.

Reduced memory required during decode_tile16384x16384 test by not converting
large grayscale test image to color image during read.

Useless output to console fixed;
Test output files moved from cwd to temp folder.

Our prebuilt FFmpeg Windows binaries don't have PNG support enabled
(because that requires zlib), so that makes a PNG image a bad choice
for this test.

When FFmpeg doesn't support PNG, VideoCapture falls back to the
"image sequence" implementation, which doesn't work for single images.

Need to go back at some point and fix this for real.

(cherry picked from commit dfe07df8)

Newer FFmpeg prohibits 4096x4096 MPEG-2, presumably because it violates
the standard.

This should actually remove the need for the workaround from
the previous commit.

Correct reading PNG color type palette with or without alpha imread flags -1 or 1
Better not using pnginfo.h, using png_get_tRNS instead

Looks like we don't actually use them; when creating precompiled headers
with Visual C++, a dummy .cpp is created at build time.

Calib3d badarg tests fixed. Default exception handling enabled;
Highgui Video I/O tests fixed on ARM;
Code cleanup.

Bug in Video for Windows capture init fixed;
Media Foundation based capture finalization fixed;
Highgui tests for video i/o updated.

Video i/o tests enabled for media foundation;
Negative stride support added to VideoCapture;
Error handling improved, dead lock in case of playback error fixed;
Some code refacotring done.
