bugfix for highgui crash on Windows in debug mode (ticket #752) has been propagated from branch 2.2 to trunk

[~] Updated GPU module install target to copy NCV.hpp and NPP_staging.hpp to the package include directory

[+] Added 128-bit transpose

If a pipeline is specified manually, this has to be done in full now, ending with appsink. For example:

"uridecodebin uri=file:///path/to/some/video.avi ! ffmpegcolorspace ! appsink"

* removed unnecessary memcpy
* fixed minor memory leak

moved precomp.hpp before all other headers (to repair PCH mechanism). moved tables from the header to datamatrix.cpp

some more minor fixes in datamatrix: warnings eliminated, replaced MMX intrinsics (which are not recommended to use on x64) with SSE2.
