qemu-option: Don't reinvent append_option_parameters()
parse_option_parameters() may need to create a new option parameter listfrom a template list. Use append_option_parameters() instead ofduplicating the code.

Fix tiny leak in qemu_opts_parse
qemu_opts_create duplicates the id we pass in case it shall be stored inthe opts. So we do not need to dup it in qemu_opts_parse, leaking a fewbytes this way.

qemu-opts: Release id on deletion
The opts id is always allocated via qemu_strdup, so it need not beconst, but it has to be released on opts deletion.
Remove bogus error message from qemu_opts_set()
The only way qemu_opts_create() can fail is if a QemuOpts with that idalready exists and fail_if_exists=1. In that case, we already printan error which makes more sense than the one in qemu_opts_set().
