ConvertToI420 and ConvertToARGB support the use of a negative height
parameter to flip the image vertically. When converting from NV12 or
NV21 this parameter was misinterpreted, resulting in invalid output.
This CL introduces the use of abs_src_height to correctly calculate
the location of the source UV plane.
The sign of crop_height is not used, to reduce confusion ConvertToI420
and ConvertToARGB no longer accept negative crop height.
Unit tests for Android420ToI420 are updated to fix miscalculation of
src_stride_uv, fix incorrect pixel strides, and to test inversion.
New unit tests are included to test inversion for ConvertToARGB,
ConvertToI420, Android420ToARGB, and Android420ToABGR.
For consistency the test NV12Crop is renamed ConvertToI420_NV12_Crop.

add macros to enable/disable code analyst around blocks of code.
Normally these macros should not be used, but if performance
details are wanted for intel code, enable them around the code
and then run via the iaca tool, available on the intel website.

YUV 411 is very uncommon format. Remove support.
Update documentation to reflect that 411 is deprecated.
Simplify tests for YUV to only test with the new side by side YUV but keep old 3 plane test around with a macro for now.
