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.

christian.brunschen f09b742ea2 * Throw the actual exception objects, rather than pointers to them, i.e.: 
- replace |throw new FooException()| with |throw FooException()|
  - 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)
* Add 'const' to the 'char *' declarations for character encoding names

dswitkin ce1badea71 Sean had a good idea to add @deprecated Javadoc comments to these three methods to help track down their usage. We can't use a Java @Deprecated annotation because core builds against Java 1.2.

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.

dswitkin 5f2b64ee50 Used IntelliJ's amazing refactoring functions to change the argument ordering of ByteMatrix. I want to standardize this across ZXing: the first component should always be horizontal and the second vertical, whether supplying an x, y point or a width, height pair. Also, we should always use x and y as variables with x being the horizontal component to avoid confusion.
