crypto/tls: rewrite some messages with golang.org/x/crypto/cryptobyte

Browse source

As a first round, rewrite those handshake message types which can be
reused in TLS 1.3 with golang.org/x/crypto/cryptobyte. All other types
changed significantly in TLS 1.3 and will require separate
implementations. They will be ported to cryptobyte in a later CL.

The only semantic changes should be enforcing the random length on the
marshaling side, enforcing a couple more "must not be empty" on the
unmarshaling side, and checking the rest of the SNI list even if we only
take the first.
