Subject: [PATCHv10 1/6] libvirt/qemu - clean up for qemudDomainAt(de)tachDevice(Flags)

Centralize device modification in the more flexible APIs, to allow
future honoring of additional flags.  Explicitly reject the
VIR_DOMAIN_DEVICE_MODIFY_FORCE flag on attach/detach.

Based on Eric Blake<eblake redhat com>'s work.

* src/qemu/qemu_driver.c 
(qemudDomainAttachDevice)(qemudDomainAttachDeviceFlags): Swap bodies, and rename...
(qemudDomainDetachDevice, qemudDomainDetachDeviceFlags): Likewise.
