Subject: [PATCH 1/2] handshake: do not enable KTLS if custom pull/push
functions are set
If gnutls_transport_set_pull_function or
gnutls_transport_set_push_function is used, we can't assume the
underlying transport handle is an FD.

Subject: [PATCH 2/2] socket: only set pull/push functions when --save-*-trace
is used
This allows gnutls-cli to use KTLS for the transport, unless either
--save-client-trace or --save-server-trace is used.

Subject: [PATCH] KTLS: hotfix
session->internals.pull_func is set to system_read during gnutls_init()
so check for user set pull/push function added in commit mentioned
bellow will never pass.
