This patch adds sync modes on top of the work that Stefan Hajnoczi has done.
These patches apply on kevin/block. Hopefully all is in order as this is my first QEMU patch. Many thanks to Stephan and Fam Zheng for their help. V2: - No longer poll, instead use qemu_coroutine_yield(). - Use bdrv_co_is_allocated(). - Much better SYNC_MODE_NONE test. V3: - A few style fixes. - Better commit message explaining how TOP and NONE operate. - Verified using checkpatch.pl. V4: - Add patch to use the source as a backing hd during backup. - Add patch to default sync mode none to qcow2. V5: - Fix qcow2 patch. Forgot to git add final version. V6: - Default to requiring 'format' when mode is absolute-paths. - Removed one bad hunk that was misapplying. - Fixed docs, examples and tests to match changes. - Added tests for format bad/missing. - Added bdrv_set_in_use() to target. - Default to qcow2 patch not required.
