Improve comments to indicate actual usage of WORDS_BIGENDIAN where
it is tested with #ifdef rather than #if

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.

This fixes build on PowerPC where Eigen unsets vector, bool and pixel

OpenCV Error: Unknown error code -6 (OpenCL function is not available: [clGetPlatformIDs]) in opencl_check_fn, file /home/ahb/software/opencv/modules/ocl/src/cl_runtime/cl_runtime.cpp, line 83

The issue results from modules/ocl/src/cl_runtime/cl_runtime.cpp checking for
"linux" instead of "__linux__" (cp.  http://sourceforge.net/p/predef/wiki/OperatingSystems/)

Adjust all other occurrences of "defined(linux)" as well.

_MSC_VER -> defined _MSC_VER. Fixes building with MinGW.
Similar to fbc91c5e.

FFmpeg 2.0.2 32-bit builded with mingw (4.6.1) with following additional options: --enable-w32threads --disable-iconv --cpu=i686 (workaroud for http://trac.ffmpeg.org/ticket/2363)

While the FFmpeg video IO backend gets compiled even without it,
the tests (for both FFmpeg and video IO) don't. This should fix
that.

Odd that it wasn't merged automatically...

folowing additional options: --enable-w32threads, --arch=i686 (for 32-bit
library, workaround for http://trac.ffmpeg.org/ticket/2363)

Allow to build samples via OpenCV binaries from distribution package
(find_package with OpenCV_DIR).

add INSTALL command for TBB target

Android 4.3 support added;
ANY camera index support fixed;
applyProperties now uses camera->reconnect() instead close/connect for Android 4.x.
(cherry picked from commit fff91eef)

They're not listed in the documentation for the FindZLIB module,
so we shouldn't use them unless necessary.

for libpng added.

Android 4.3 support added;
ANY camera index support fixed;
applyProperties now uses camera->reconnect() instead close/connect for Android 4.x.

Debug library name prefix changed no "_debug" to fit pragmas in TBB
headers.
