broken-out patch stats

Tim started trying to generate a broken-out patch set (with quilt), from the Android common tree as of August 2011. This is how far he got before he had to work on other things. The following list has 59 patches. 'remainder 32' at the end was where he stopped. Some of these are directly extracted from a single or multiple commits in the Android source tree.

This is here mainly for a quick review.
