srowen e1dd41a115 Improve detector logic to throw out false positive finder patterns in a more reasonable manner. Current logic didn't quite achieve its goal in some corner cases and needed rethinking and some simplification. Fixes a reported failure from the group list. Net change in passed test cases is -1 otherwise (for 270 degree rotation -- not vital) so I consider it a net tiny win.

dswitkin b238cb7828 I noticed that the codeword coordinates in PDF 417 barcodes were a few pixels off if there was skew or rotation in the image. I added a simple method to correct the vertical component of these points, and the units tests went from 8/23 to 11/23.

dswitkin 01eed5266e - Converted parts of the PDF 417 reader to use BitMatrix. 
- Changed the PDF 417 detector to search the image more broadly, instead of assuming the barcode starts in the left 1/4 and ends in the right 1/4. We now get 8/23 on the real-world blackbox test, and we'll probably do even better with further improvements here.
- Added a quiet zone to two of the unit test images and updated a golden result for one of them. We now get 3/7 on the first test.
- Tried to fix some bugs in the upside down code but it still doesn't work.

dswitkin 10dfe7789b - Got the DataMatrix decoder compiling again with a quick bandaid. 
- Fixed two bugs in the LocalBlockBinarizer sharpening routine. It can now decode 2132 images in our blackbox tests, compared to 2103 using the global histogram approach.
- Added the PDF 417 blackbox test to AllPositiveBlackBoxTester, and allowed it to complete even if the tests fail.

  - replace |catch (FooException *ex)| with |catch (FooExceptio ex)|
  - update all uses of caught exceptions appropriately:
    . replace |ex->foo| with |ex.foo|
    . remove all attempts to delete the caught exception(s)

dswitkin 167197ec7a Refactored the MonochromeBitmapSource class hierarchy into LuminanceSource, Binarizer, and BinaryBitmap classes. The unit tests pass and I believe the change is complete, but there are some clients like J2ME and Bug that I can't build. 
This change will allow new thresholding algorithms to be developed and tested, as well as implemented per platform if needed (e.g. in JNI on Android). It should also perform better when multiple 2D Readers are installed, because the underlying image will only be converted to 1 bit once. It also allows some platforms to return luminance data without a copy.

The current state of this checkin is to use the old black point algorithm, which now lives in GlobalHistogramBinarizer. This will be our benchmark and fallback for slower platforms. Going forward we will begin to use LocalBlockBinarizer as I shake out the edge cases and tune it for performance. Currently it is unused.

IMPORTANT: I have temporarily included three methods from MonochromeBitmapSource at the end of BinaryBitmap as a way to make this change in stages. They are deprecated and will be removed soon. All of the Reader classes will need to change the way they examine 1 bit pixels to use the new getBlackRow() and getBlackMatrix() calls.
