Only define BUILD_BUG_ON when there isn't one already, because mini-os
currently leaks that.

read_record() could be used by primary to read dirty bitmap
record sent by secondary under COLO.
When used by xc save side, we need to pass the backchannel fd
instead of ctx->fd to read_record(), so we added a fd param to
it.
No functional changes.

Provide the C structures matching the binary (wire) format of the new
stream format. All header/record fields are naturally aligned and
explicit padding fields are used to ensure the correct layout (i.e.,
there is no need for any non-standard structure packing pragma or
attribute).
Provide some helper functions for converting types to string for
diagnostic purposes.
