qcow2: Round QCowL2Meta.offset down to cluster boundary

The offset within the cluster is already present as n_start and this is
what the code uses. QCowL2Meta.offset is only needed at a cluster
granularity.

qcow2: Introduce Qcow2COWRegion

This makes it easier to address the areas for which a COW must be
performed. As a nice side effect, the COW code in
qcow2_alloc_cluster_link_l2 becomes really trivial.

atapi: reset cdrom tray statuses on ide_reset

Tray statuses should be also reseted. Some guests may lock the tray
and after reset before any kernel is loaded the tray should be unlocked.

Also if you reset the real computer the tray is closed. We should
do the same in qemu....

blkdebug: Allow usage without config file

As soon as new rules can be set during runtime, as introduced by the
next patch, blkdebug makes sense even without a config file.

blkdebug: Factor out remove_rule()

The cleanup work to remove a rule depends on the type of the rule. It's
easy for the existing rules as there is no data that must be cleaned up
and is specific to a type yet, but the next patch will change this.

blkdebug: Implement suspend/resume of AIO requests

This allows more systematic AIO testing. The patch adds three new
operations to blkdebug:

  • Setting a "breakpoint" on a blkdebug event. The next request that
    triggers this breakpoint is suspended and is tagged with a name....

qemu-io: Add AIO debugging commands

This makes the blkdebug suspend/resume functionality available in
qemu-io. Use it like this:

$ ./qemu-io blkdebug::/tmp/test.qcow2
  qemu-io> break write_aio req_a
  qemu-io> aio_write 0 4k
  qemu-io> blkdebug: Suspended request 'req_a'...

qcow2: Move BLKDBG_EVENT out of the lock

We want to use these events to suspend requests for testing concurrent
AIO requests. Suspending requests while they are holding the CoMutex is
rather boring for this purpose.

qemu-iotests: Test concurrent cluster allocations

This adds some first tests for qcow2's dependency handling when two
parallel write requests access the same cluster.
