306783d6f5 lib: modules: Change XXX_init interface from XXX_init(void) to XXX_init(TALLOC_CTX *)
Not currently used - no logic changes inside.

This will make it possible to pass down a long-lived talloc
context from the loading function for modules to use instead
of having them internally all use talloc_autofree_context()
which is a hidden global.

Updated all known module interface numbers, and added a

79f5275db2 auth/gensec: add a gensec_update_ev() function
This is the current gensec_update() which takes an optional
tevent_context structure and allows semi-async code.

This is just a temporary solution on the way to kill
the semi-async code completely, by using gensec_update_send/recv.

By providing a gensec_update_ev(), we can remove the explicit
tevent_context from gensec_update() and fix all the sane callers.

149f8f16be s4-gensec: Move parsing of the PAC blob and creating the session_info into auth

format until it becomes a struct auth_session_info.

0d5de7e19c gensec: Assert that we have not been subject to a downgrade attack in DCE/RPC clients
Because of the calling convention, this is the best place to assert
that we have not been subject to a downgrade attack on the negotiated

35b309fa0c gensec: clarify memory ownership for gensec_session_info() and gensec_session_key()
This is slightly less efficient, because we no longer keep a cache on
the gensec structures, but much clearer in terms of memory ownership.
Both gensec_session_info() and gensec_session_key() now take a mem_ctx
and put the result only on that context.

Some duplication of memory in the callers (who were rightly uncertain
about who was the rightful owner of the returned memory) has been
removed to compensate for the internal copy.
