SINGA-215 Implement Image Transformation for Image Pre-processing

Implement some of the image transformations (i.e., crop, resize, horizontal_mirror) for pre-processing stage.

Image resize need to use opencv library.

Currently image transformation only support one sample input each time.

Add static function resize, crop and mirror for image transformation.

Training phase use random crop and random mirror,
Evaluation phase use central crop and no mirror.

Cannot test phases for mirror because of a random factor.

Fix bugs in test files involving memory allocation and access.
