Did a big refactoring on the MonochromeBitmapSource. I removed all the caching luminance calls and converted them to getting luminance data on demand. This saved another 33,000 function calls per rejected scan, good for another 15 ms savings. I also moved the luminance calls to BaseMonochromeBitmapSource and made them protected, to indicate that the decoders shouldn't use them.
...
Overall the recent optimizations took one rejected scan from 307 to 135 ms, which is definitely noticeable.
WARNING: I am not able to build the Bug or J2ME clients, but I believe they are correct.

Looks like -allowaccessmodification to ProGuard results in a bogus binary. It compiles, but the Dalvik verifier rejects it at runtime. I'm removing this flag for now, which means we lose inlining on some important getters and setters.

Added androidtest to the top-level clean target and set it up for ProGuard too. Made both Android builds depend on clean so they work when switching between normal and ProGuard builds, and made install and reinstall use the latest binary instead of recompiling.

Updated the Android benchmark with more accurate timing and better results output. Also fixed walking the tree to use a consistent order to make comparison between the device and emulator easier.

Wrote a benchmark activity for Android which reads images recursively from the SD card, decodes each 10 times, and prints the average time to decode in milliseconds. The UI is extremely minimal, as the results are written to the log, but this is a good start towards measuring our performance under Dalvik on a platform without floating point hardware. This should run fine on the emulator but I haven't tested it yet.

Checked in the ZXing Test app for Android under androidtest. This application exercises all the intents we support including scanning, encoding, and searching books. It also has a special camera mode which saves greyscale images to the SD card which I use to generate blackbox images.
