Allocate and return a new empty message block of size span_size mimicking parameters of mb. This function allocates a new aligned message block using the same allocators and flags as found in mb. The size of the new message block is at least span_size; the size may be adjusted up in order to accomodate alignment requirements and still fit span_size bytes into the aligned buffer.
