Now that the old qcow2 encryption is removed we can safely delete all
this code since it's not needed any more.

The encryption was buggy and qemu actually dropped it upstream. Forbid
it for all versions since it would cause other problems too.

Problems with the old encryption include weak crypto, corruption of
images with blockjobs and a lot of usability problems.

This requires changing of the encryption type for the encrypted disk
tests.

We need to check if TLS is enabled as the variable is a tristate.
Currently we'd setup TLS even if it was explicitly turned off.
Thankfully TLS for disks was only used with the vxhs protocol so hardly
anybody would ever be able to hit the problem.

Disks are client-only so we don't need to have this variable. We also
always pass false for 'isListen' to qemuBuildTLSx509BackendProps for all

Use the new monitor command internal API to allow wrapping of the object
name and alias into the JSON props so that they don't have to be passed
out of band.

The new API also takes a double pointer so that it can be cleared when
the value is consumed so that it does not need to happen in every single
caller.

qemuBuildTLSx509CommandLine has no business guessing which alias should
be used. The alias needs to be passed in.

Note that there's a lingering bad design of this, since the secret
object alias is based on the device name and not on the fact that the
secret is used for decrypting of the TLS private key. If we ever add
authentication for chardevs this will bite us.

Thankfully disk code does not support encrypted private keys for TLS so
it can be happily refactored there.
