Log a debugging message, rather than using gp_context_message, for an   unexpected length returned from "get camera photo abilities". Added "keys_locked" member to the camera data, and unlock only when we   think the camera has been left locked. This should be never for EOS   cameras, and useless for other models, as we don't know how to   unlock those. Trying a different command code for key lock and unlock for EOS 20D. Corrected comments in canon_usb_dialogue. Added some casts to avoid warnings on both Linux and Darwin, since one   defines size_t as long, the other as int.
