This was done with the help of callcatcher [1]. Only functions which are statically known to be unused are removed. Some unused functions are not removed yet, because they might be needed in the near future (such as open_output_stream for the encode branch). There is one user visible change: the --subcc option did nothing, and is removed with this commit. [1] http://www.skynet.ie/~caolan/Packages/callcatcher.html
