Subject: [PATCH] Rename {Reader,Writer}ByteConversions methods

The method names in std::rt::io::extensions::WriterByteConversions are
the same as those in std::io::WriterUtils and a resolve error causes
rustc to fail after trying to find an impl of io::Writer instead of
trying to look for rt::io::Writer as well.

Same goes for ReaderByteConversions.
