rbutil: improve voice and talk generation.
- introduce a talkgenerator to better share code between voice and talk generation. - name intermediate .talkfiles after the md5sum of the text. (prevents naming problems). - do not directly use the logger, instead emit signals. - move talkfile and voicefile generation to base/ git-svn-id: svn://svn.rockbox.org/rockbox/trunk@21524 a1c6a512-1295-4272-9138-f99709370657
