From 29e6158507a0758192075ac6ece7ba8e75ddc49a Mon Sep 17 00:00:00 2001

Subject: small API change: do no longer pass rarely needed
 GNUNET_SCHEDULER_TaskContext to all scheduler tasks; instead, allow the
 relatively few tasks that need it to obtain the context via
 GNUNET_SCHEDULER_get_task_context()
