If an error occurs in bdrv_snapshot_delete_by_id_or_name(), "err" is freed. If "err" is not set to NULL before calling bdrv_snapshot_delete_by_id_or_name() again, it will not be updated on error, and will be freed again. This can be triggered by starting a VM with at least two drives and then attempting to delete a non-existent snapshot. Broken in commit a89d89d3.

This commit adds a new command, '-dump-vmstate', that takes a filename as an argument. When executed, QEMU will dump the vmstate information for the machine type it's invoked with to the file, and quit. The JSON-format output can then be used to compare the vmstate info for different QEMU versions, specifically to test whether live migration would break due to changes in the vmstate data. A Python script that compares the output of such JSON dumps is included in the following commit.

Snapshot creation actually already distinguish id and name since it take a structured parameter *sn, but delete can't. Later an accurate delete is needed in qmp_transaction abort and blockdev-snapshot-delete-sync, so change its prototype. Also *errp is added to tip error, but return value is kepted to let caller check what kind of error happens. Existing caller for it are savevm, delvm and qemu-img, they are not impacted by introducing a new function bdrv_snapshot_delete_by_id_or_name(), which check the return value and do the operation again. Before this patch: For qcow2, it search id first then name to find the one to delete. For rbd, it search name. For sheepdog, it does nothing. After this patch: For qcow2, logic is the same by call it twice in caller. For rbd, it always fails in delete with id, but still search for name in second try, no change to user. Some code for *errp is based on Pavel's patch. Signed-off-by: NWenchao Xia <xiawenc@linux.vnet.ibm.com> Signed-off-by: NPavel Hrdina <phrdina@redhat.com> Signed-off-by: NKevin Wolf <kwolf@redhat.com>

These are the prototypes and implementation of new hooks that RDMA takes advantage of to perform dynamic page registration. An optional hook is also introduced for a custom function to be able to override the default save_page function. Also included are the prototypes and accessor methods used by arch_init.c which invoke funtions inside savevm.c to call out to the hooks that may or may not have been overridden inside of QEMUFileOps.

To avoid conflict and tip better, macro in header file is BLOCK_QAPI_H instead of QAPI_H. Now block.h and snapshot.h are at the same level in include path, block_int.h and qapi.h will both include them.
