Subject: auth/gensec: add a gensec_update_ev() function
X-Git-Tag: ldb-1.1.17~477
X-Git-Url: http://git.samba.org/samba.git/?p=kai%2Fsamba-autobuild%2F.git;a=commitdiff_plain;h=79f5275db2c1acd5adaee187c3953fbc5e2aff6c

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.
