Use the qemu specific callback to fill this data in the qemu driver as
it's the only place where it was used and fix tests as the qemu test
capability object didn't configure the defaults for the tests.
Without this patch, logged command executions can be ambiguous if
the command contained any shell metacharacters. This has caused
more than one person to attempt to patch clients to add unnecessary
quoting, without realizing that the command itself was run with
correct args, and only the logged output was ambiguous.
* src/util/command.c (virCommandToString): Add shell escapes.
* tests/commandtest.c (test16): Test new behavior.
* tests/commanddata/test16.log: Update expected output.
* tests/qemuxml2argvdata/qemuxml2argv-*.args: Likewise.
* tests/networkxml2argvdata/*.argv: Likewise.
This works with newer qemu that doesn't allow escaping spaces.
It's backwards compatible as well.

This improves the support for qemu rbd devices by adding support for a few
key features (e.g., authentication) and cleaning up the way in which
rbd configuration options are passed to qemu.
An <auth> member of the disk source xml specifies how librbd should
authenticate. The username attribute is the Ceph/RBD user to authenticate as.
The usage or uuid attributes specify which secret to use. Usage is an
arbitrary identifier local to libvirt.
The old RBD support relied on setting an environment variable to
communicate information to qemu/librbd. Instead, pass those options
explicitly to qemu. Update the qemu argument parsing and tests
accordingly.
