[svn-r16985] Description:
Interim checkin of work toward closing race condition window which can
cause errors when reading a file that is used for SWMR-write access.
This change introduces a chunk proxy in the metadata cache, which
participates in the metadata cache's flush dependencies while representing a
raw data chunk in a dataset's chunk cache.
Also, the extensible array's SWMR behavior is only invoked when the
file is opened for SWMR-write access, allowing more flexibility in flushing
extensible array data structure pieces when SWMR-write is not enabled.
Tested on:
