From: Chuck Lever <chuck.lever@oracle.com>

Kernel TLS consumers will need definitions of various parts of the
TLS protocol, but often do not need the function declarations and
other infrastructure provided in <net/tls.h>.

Break out existing standardized protocol elements into a separate
header, and make room for a few more elements in subsequent patches.
