Remove dead code

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.
