v5:
Add qemu-iotests for qcow2 shrinking. Do some modifications based on MAX's
suggestions in v4.
v4:
Add deal with COW clusters in l2 table. When using COW, some of (l2_entry >>
s->cluster_bits) will larger than s->refcount_table_size, so need to discard
this l2_entry.
v3:
Fixed host cluster leak.
In file block/qcow2.c, just using ftruncate to fix host cluster leak.
In file block/qcow2-cluster.c, just re-copy qcow2_grow_l1_table to
realize qcow2_shrink_l1_and_l2_table.
In file block/qcow2-refcount.c, also update the realization to handle
self-describing
refcount blocks in function update_refcount.
Thanks.
