Extend return codes for chinachip_patch().
Instead of passing error messages using a callback function (which becomes awkward when used from a C++ class object) return distinct error codes from chinachip_patch(). This also removes the kludge to support translations for Rockbox Utility and moves the strings to translate to the installation class where they belong. As a side effect info messages won't be passed to Rockbox Utility anymore, but the details of the patching progress aren't of that much interest for the user anyway. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31115 a1c6a512-1295-4272-9138-f99709370657
