qemu: PCI device, disk and host network hot-add / hot-remove (Marcelo Tosatti)

Browse source 
Add monitor command to hot-add PCI devices (nic and storage).
    
Syntax is:
    
pci_add pci_addr=[[<domain>:]<bus>:]<slot> nic|storage params
    
It returns the domain, bus and slot for the newly added device on success.
    
It is possible to attach a disk to a device after PCI initialization via
the drive_add command. If so, a manual scan of the SCSI bus on the guest
is necessary.
    
Save QEMUMachine necessary for drive_init.
    
Add monitor command to hot-remove devices, remove device data on _EJ0 notification.
