qemu-file: temporarily expose qemu_file_set_error and qemu_fflush
Right now, migration cannot entirely rely on QEMUFile's automatic drop of I/O after an error, because it does its "real" I/O outside the put_buffer callback. To fix this until buffering is gone, expose qemu_file_set_error which we will use in buffered_flush. Similarly, buffered_flush is not a complete flush because some data may still reside in the QEMUFile's own buffer. This somewhat complicates the process of closing the migration thread. Again, when buffering is gone buffered_flush will disappear and calling qemu_fflush will not be needed; in the meanwhile, we expose the function for use in migration.c.
