context: separateworkingctx stats and raw status

Split the workingctx _status property cache into _status, which is
possibly filtered, and _rawstatus which is never filtered.  By
default, _status proxies to _rawstatus, and then replaces itself with
the results.  Calling status() will update the _status property.
Subsequent changes will change status() to sometimes result in
filtered changes getting written to _status.  the point of this change
is to make sure the workingctx will have access to the unfiltered
status.
