Change parameter of send_auth_pending_messages from context to tls_multi

Change parameter of send_auth_pending_messages from context to tls_multi

This prepares send_auth_pending_messages to be used a in context that
does not have context c available but also does not need to schedule
an immediate sending of the message (auth plugin/script)

Patch V2: Adjust the comment of reschedule_multi_process to actually fit a
          function.

Patch V3: Rebase needed because v3 of 3/11

Patch V4: Send with push.h prototype
