Introduce a new qemuDomainObjPrivate object which is used to store
the private QEMU specific data associated with each virDomainObjPtr
instance. This contains a single member, an instance of the new
qemuMonitorPtr object which encapsulates the QEMU monitor state.
The internals of the latter are private to the qemu_monitor* files,
not to be shown to qemu_driver.c
* src/qemu/qemu_conf.h: Definition of qemuDomainObjPrivate.
* src/qemu/qemu_driver.c: Register a functions for creating
and freeing qemuDomainObjPrivate instances with the domain
capabilities. Remove the qemudDispatchVMEvent() watch since
I/O watches are now handled by the monitor code itself. Pass
a new qemuHandleMonitorEOF() callback into qemuMonitorOpen
to allow notification when the monitor quits.
* src/qemu/qemu_monitor.c, src/qemu/qemu_monitor.h: Introduce
the 'qemuMonitor' object. Temporarily add new APIs
qemuMonitorWrite, qemuMonitorRead, qemuMonitorWaitForInput
to allow text based monitor impl to perform I/O.
* src/qemu/qemu_monitor_text.c: Call APIs for reading/writing
to monitor instead of accessing the file handle directly.
The qemu_driver.c code should not contain any code that interacts
with the QEMU monitor at a low level. A previous commit moved all
the command invocations out. This change moves out the code which
actually opens the monitor device.
* src/qemu/qemu_driver.c: Remove qemudOpenMonitor & methods called
from it.
* src/Makefile.am: Add qemu_monitor.{c,h}
* src/qemu/qemu_monitor.h: Add qemuMonitorOpen()
* src/qemu/qemu_monitor.c: All code for opening the monitor
