Much of adb is duplicated in bootable/recovery/minadb and fastboot. Changes made to adb rarely get ported to the other two, so the trees have diverged a bit. We'd like to stop this because it is a maintenance nightmare, but the divergence makes this difficult to do all at once. For now, we will start small by moving common files into a static library. Hopefully some day we can get enough of adb in here that we no longer need minadb. Bug: 17626262 Change-Id: Ic8d5653bfcc0fec4e1acbece124402355084b864
