migration: qemu-file more size_t'ifying
This time convert the external functions: qemu_get_buffer, qemu_peek_buffer qemu_put_buffer and qemu_put_buffer_async Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Message-Id: <1439463094-5394-6-git-send-email-dgilbert@redhat.com> Reviewed-by: zhanghailiang <zhang.zhanghailiang@huawei.com> Reviewed-by: Amit Shah <amit.shah@redhat.com> Signed-off-by: Amit Shah <amit.shah@redhat.com>
