Kevin Wolf 1b9f1491f8 qcow2: Unlock during COW 
Unlocking during COW allows for more parallelism. One change it requires is
that buffers are dynamically allocated instead of just using a per-image
buffer.

While touching the code, drop the synchronous qcow2_read() function and replace
it by a bdrv_read() call.
