Define remote wire protocol & impls for virDomainQemuAttach

Browse Source 
This tweaks the RPC generator to cope with some naming
conventions used for the QEMU specific APIs

* daemon/remote.c: Server side dispatcher
* src/remote/remote_driver.c: Client side dispatcher
* src/remote/qemu_protocol.x: Wire protocol definition
* src/rpc/gendispatch.pl: Use '$structprefix' in method
  names, fix QEMU flags and fix dispatcher method names
