qemu-option: Add qemu_opts_absorb_qdict()
This adds a function that adds all entries of a QDict to a QemuOpts if the keys are known, and leaves only the rest in the QDict. This way a single QDict of -drive options can be processed in multiple places (generic block layer, block driver, backing file block driver, etc.), where each part picks the options it knows. If at the end of the process the QDict isn't empty, the user specified an invalid option.
