Cover basic aspects and API usage for QemuOpt. The current implementation covers the API's planned to be changed by Chunyan Liu in his QEMUOptionParameter replacement/cleanup job. Other APIs should be covered in future improvements. [Squashing in a small fix "QemuOpt: use qemu_find_opts_err() to avoid output on stderr in tests". qemu_find_opts() calls error_report() instead of propagating the Error object. It is undesirable to clutter test case output with error messages from a passing test. Use qemu_find_opts_err() to avoid the output on stderr. --Stefan] Signed-off-by: Leandro Dorileo <l@dorileo.org> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
