A constant buffer sequence represents a set of memory
regions that may be used as input to an operation, such as the send
operation of a socket.
A type X meets the ConstBufferSequence requirements
if it satisfies the requirements of Destructible (C++Std [destructible])
and CopyConstructible (C++Std [copyconstructible]), as well
as the additional requirements listed below.
In the table below, x denotes a (possibly const) value of type
X, and u denotes an identifier.
