template <typename Callback>zx_status_t ForEach (Callback callback)Iterate through the iovec.
The expected signature for the callback is:
zx_status_t (callback)(PtrType ptr, size_t capacity).
To continue to the next buffer in the vector, return ZX_ERR_NEXT. To stop
iterating successfully, return ZX_ERR_STOP. Returning any other error will
also stop the iteration but will cause ForEach to retun that error instead
of ZX_OK.
