Add support (on Linux and win32 only - I couldn't figure this out on OS X) for reading the XML device information from ipods. This information includes the RAM size, which is potentially useful for rbutil to distinguish between the two ipod video builds. This is implemented as both a new --dump-xml option (to dump the entire XML to a file) and a new 'ramsize' field in struct ipod_t.
