[libvirt] [PATCHv1 09/12] qemu_capabilities: Persist QEMU instance over multiple QMP Cmds

[Chris Venteicher]

Makes possible to start a single QEMU instance and use that one instance
for multiple independent QMP commands without starting and stopping QEMU
for each QMP command type.

This allows functions outside qemu_capabilities
(ex.  qemuConnectBaselineHypervisorCPU in qemu_driver)
requiring multiple different QMP messages to be sent to QEMU to issue
those requests over a single QMP Command Channel without Starting and
Stopping QEMU for each independent QMP Command usage.

Now in Global Scope:
struct virQEMUCapsInitQMPCommand
virQEMUCapsInitQMPCommandFree
