qmp: make block job command naming consistent

The block streaming and job commands used '_' instead of '-' for reasons
of compatibility with libvirt, which already included support for the
'_' naming.  However, the semantics of block_job_cancel have changed and
libvirt now needs to handle the new semantics.

Since the old semantics were never in a QEMU release we can still rename
the commands to use '-' instead of '_'.  Libvirt is also happy because
the new name can be used to distinguish QEMU binaries that support the
latest block-job-cancel semantics from those that include a downstream
block_job_cancel command.

Therefore, let's apply the QAPI/QMP naming rules to the block streaming
and job commands.  QEMU 1.1 will be the first release with these
commands so no upstream users can break.

are QCOW_OFLAG_COPIED and QCOW_OFLAG_COMPRESSED to properly mask out
reserved bits.

It does not convert bdrv_check yet.

qcow2: Fail write_compressed when overwriting data

qcow2_alloc_compressed_cluster_offset() already fails if the copied flag
is set, because qcow2_write_compressed() doesn't perform COW as it would
have to do to allow this.

However, what we really want to check here is whether the cluster is
allocated or not. With internal snapshots the copied flag may not be set
on allocated clusters. Check the cluster offset instead.

Specification for qcow2 version 3

This updates the qcow2 specification to cover version 3. It contains the
following changes:

- Added compatible/incompatible/auto-clear feature bits plus an optional
  feature name table to allow useful error messages even if an older
  version doesn't know some feature at all.

- Configurable refcount width. If you don't want to use internal
  snapshots, make refcounts one bit and save cache space and I/O.

- Zero cluster flags. This allows discard even with a backing file that
  doesn't contain zeros. It is also useful for copy-on-read/image
  streaming, as you'll want to keep sparseness without accessing the
  remote image for an unallocated cluster all the time.

- Fixed internal snapshot metadata to use 64 bit VM state size. You
  can't save a snapshot of a VM with >= 4 GB RAM today.

- Extended internal snapshot metadata to contain the disk size, so that
  resizing images that have snapshots can be allowed in the future.
