Add isManaged / makeManaged

Summary: Add a way to tell whether an IOBuf (either indvidually or the whole chain)
refers to memory that's outside of IOBuf's control (via WRAP_BUFFER). That is,
can you assume that clone() will extend the lifetime of the memory? Is it safe
to use clone() instead of copying the data (and avoid a copy)?
