This removes all calls to inAnnex, except for some involving --batch. It may be that the batch code could get a similar speedup, but I don't know if people habitually pass a huge number of files through --batch that git-annex does not need to do anything to process, so I skipped it for now. A few calls to ifAnnexed remain, and might be worth doing more to convert. In particular, Command.Sync has one that would probably speed it up by a good amount. (also removed some dead code from Command.Lock)
