Fixes toward EOS 20D support:  o "flash device ID", "get disk info", and "delete file"    have different command codes.  o "get disk info" seems to return values in K rather than bytes. Moved PowerShot A60 & A70 from class 5 to class 1. Casts on various parameters to avoid warnings both on Linux and   on Mac OS X, which seem to have different sizes for size_t. Changed to use all 32 bytes, if present, from both camera   model and owner name from "identify camera" command. Some realignment.
