Handle buffer alloc failure in vlib_buffer_add_data
It's not OK to crash due to a transient buffer allocation failure.
Return 1 if the requested operation failed, otherwise 0.
Buffer index parameter change to a value-result, so the caller can
differentiate between partial and complete allocation failure: callers
which request an initial allocation (inbound bi = ~0) need to check
the (out) value to decide whether or not to call vlib_buffer_free(...).
