Delete server-side deleteThis()

Delete server-side deleteThis()

This patch finishes the conversion of ServerStateData into AsyncJob by properly
implementing the doneAll() method and by removing calls to deleteThis() or
replacing with mustStop() calls as appropriate.

The Adaptation::AccessCheck modified to schedule an AsyncJobCall when
access check finishes.

The ServerStateData and ClientHttpRequest classes modified to work with the new
Adaptation::AccessCheck.
