Windows: Fcb sectionObjectResource

Windows: Fcb sectionObjectResource

Add a SectionObjectResource to the AFS_FCB structure.  This lock
replaces the Fcb.Resource in protecting the SectionObjectPointers.

The new resource is being added to assist in avoiding deadlocks
caused by Trend Micro and perhaps other AV products when
CcPurgeCacheSection() is called while holding the Fcb.Resource
which is required in AFSProcessOpen().
