This extends the v3 migration protocol such that the virDomainMigrateBegin3 and virDomainMigratePerform3 methods accept an application supplied XML config for the target VM. If the 'xmlin' parameter is NULL, then Begin3 uses the current guest XML as normal. A driver implementing the Begin3 method should either reject all non-NULL 'xmlin' parameters, or strictly validate that the app supplied XML does not change guest ABI. The Perform3 method also needed the xmlin parameter to cope with the Peer2Peer migration sequence. NB it is not yet possible to use this capability since neither of the public virDomainMigrate/virDomainMigrateToURI methods have a way to pass in XML. * daemon/remote.c, src/remote/remote_driver.c, src/remote/remote_protocol.x, src/remote_protocol-structs: Add 'remote_string xmlin' parameter to begin3/perform3 RPC messages * src/libvirt.c, src/driver.h, src/libvirt_internal.h: Add 'const char *xmlin' parameter to Begin3/Perform3 methods * src/qemu/qemu_driver.c, src/qemu/qemu_migration.c, src/qemu/qemu_migration.h: Pass xmlin parameter around migration methods
