qemu_hotplug: move qemuDomainDetachDeviceLive() to qemu_hotplug.c

Browse Source 
This function is going to take on some of the functionality of its
subordinate functions, which all live in qemu_hotplug.c.

qemuDomainDetachDeviceControllerLive() is only called from
qemuDomainDetachDeviceLive() (and will soon be merged into
qemuDomainDetachControllerDevice(), which is in qemu_hotplug.c), so
it is also moved.
