47ee78048c qemu: block: Remove unused flags QEMU_BLOCK_STORAGE_SOURCE_BACKEND_PROPS_ flags
QEMU_BLOCK_STORAGE_SOURCE_BACKEND_PROPS_SKIP_UNMAP is no longer
referenced inside the code.

QEMU_BLOCK_STORAGE_SOURCE_BACKEND_PROPS_AUTO_READONLY is passed from
various code paths to the qemuBlockStorageSourceGetBackendProps helper,
but it's no longer used.

Both thus can be removed.

Legacy mode used to be needed for use with -drive, which was almost
completely deleted. We now have qemuxml2argvtest test cases checking a
few cases and the rest uses the modern mode only. Thus we don't need to
test the legacy mode any more.

b9a5541b49 qemublocktest: Use "target only" mode in 'testJSONtoJSON' and 'testBackingXMLjsonXML'
Both tests pass a disk source definition which didn't go through the
preparation steps and thus contains only the target information that
were originally present, thus we should be using the
QEMU_BLOCK_STORAGE_SOURCE_BACKEND_PROPS_TARGET_ONLY flag.

For the same reason QEMU_BLOCK_STORAGE_SOURCE_BACKEND_PROPS_AUTO_READONLY
used in 'testJSONtoJSON' doesn't make sense.

5c254bb541 conf: Store SCSI bus length in virDomainDef
Libvirt assumes that a SCSI bus can fit up to 8 devices
(including controller itself), except for so called wide bus
which can accommodate up to 16 devices (again, including
controller). This plays important role when computing 'drive'
address in virDomainDiskDefAssignAddress(). So far, the only
driver that enables wide SCSI bus is VMX. But with newer
releases, ESX is capable of "super wide" bus (64 devices).

We can blindly bump the limit in our code because then we would
compute address that's invalid for older ESX versions that we
still want to support.

Unfortunately, I haven't found a better place where to store this
than virDomainDef.

c8238579fb lib: Drop internal virXXXPtr typedefs
Historically, we declared pointer type to our types:

  typedef struct _virXXX virXXX;
  typedef virXXX *virXXXPtr;

But usefulness of such declaration is questionable, at best.
Unfortunately, we can't drop every such declaration - we have to
carry some over, because they are part of public API (e.g.
virDomainPtr). But for internal types - we can do drop them and
use what every other C project uses 'virXXX *'.

This change was generated by a very ugly shell script that
generated sed script which was then called over each file in the
repository. For the shell script refer to the cover letter:
