Hi,

The following series extends virDomainGetGuestInfo to report disk informations
provided by the new QGA "guest-get-disks" command in QEMU 5.2.

Please review,

Fixes:

Marc-André Lureau (9):
qemu_agent: rename qemuAgentDiskInfo->qemuAgentDiskAddress
qemu_agent: export qemuAgentDiskAddressFree & add g_auto
qemu_agent: factor out qemuAgentGetDiskAddress
util: json: add virJSONValueObjectGetStringArray convenience
qemu: use virJSONValueObjectGetStringArray
qemu_agent: add qemuAgentGetDisks
domain: add disk informations to virDomainGetGuestInfo
qemu_driver: report guest disk informations
virsh: add --disk informations to guestinfo command

Works for me on qemu-5.2.0-0.7.rc2.fc34.x86_64:

For the guest with qemu-guest-agent-5.2.0-0.7.rc2.fc34.x86_64:

➜ ~ virsh guestinfo pc --disks
disks.count : 2
disks.0.name : /dev/vda1
disks.0.partition : yes
disks.0.dependencies.count: 1
disks.0.dependencies.0.name: /dev/vda
disks.1.name : /dev/vda
disks.1.partition : no
disks.1.alias : vda

For the guest with qemu-guest-agent-4.1.1-1.fc31.x86_64:

➜ ~ virsh guestinfo new --disks
error: internal error: unable to execute QEMU agent command 'guest-get-disks': The command guest-get-disks has not been found
