[Bug 1762710] [NEW] gnutls_server_name_set() doesn't honour input length

[dwmw2]

Public bug reported:

        gnutls_server_name_set(sess, GNUTLS_NAME_DNS, "stophere.please",
8);

Length 8. That's supposed to set the SNI to "stophere". It doesn't in
16.04's 3.4.10-4ubuntu1.4

See attached test case.

This was supposed to be fixed upstream with commit c1334fee5ee, I
thought.

** Affects: gnutls28 (Ubuntu)
     Importance: Undecided
