Omnibus checkin for several relatively minor modifications:

1) Added code test/page_buffer.c to verify that page buffering is
   disabled in parallel builds.

2) Added code to test/cache_image.c to verify correct interaction
   between evict on close and cache image -- in particular management
   of a file containing a cache image containing dirty metadata that
   has been opened R/O.  Also fix for the bug exposed.

3) Added code to testpar/t_cache_image.c to verify expected procedure
   for reading cache images, and also supporting stats collection code
   needed for the test.

4) Repair of an overactive sanity check in H5C__reconstruct_cache_contents().

5) Other minor tidies in passing.

Tested serial and parallel, debug and production on Jelly.

 /*-------------------------------------------------------------------------
+ * Function:    evict_on_close_test()
+ *
+ * Purpose:     If a file containing a cache image which in turn 
+ *              contains dirty entries is opened R/O, the metadata 
+ *              cache must refuse to evict the dirty entries, as 
+ *              it will not be able to reload them from file.  This
+ *              is a bit tricky, as the dirty entries must marked as
+ *              clean in the metadata cache so that the MDC will not 
+ *              attempt to flush then on file close.
+ *
+ *              The objective of this test is to verify that the 
+ *              metadata will not evict dirty entries in the above
+ *              context when the file is opened with the evict on close
+ *              FAPL entry.
+ *
+ *              Do this by creating a HDF5 file with a cache image 
+ *              containing dirty metadata.  
+ *
+ *              Then close the file, re-open it R/O, and scan its 
+ *              contents twice.  If evict on close succeeds in evicting
+ *              the dirty metadata, the second scan will fail, as valid 
+ *              versions of the dirty metadata will not be available.
+ *
+ *              To make the test more useful, enable persistant free 
+ *              space managers.
+ *
+ *		The test is set up as follows:
+ *
+ *		 1) Create a HDF5 file without a cache image requested
+ *                  and persistant free space managers enabled.  
+ *
+ *		 2) Create some data sets and verify them.
+ *
+ *               3) Close the file.
+ *
+ *               4) Open the file R/W, and with cache image requested.
+ *
+ *               5) Verify the datasets created in 2) above.  This will
+ *                  force their (clean) metadata into the metadata cache,
+ *                  and hence into the cache image.
+ *
+ *               6) Create some more datasets.
+ *
+ *               7) Close the file.
+ *
+ *               8) Open the file R/O and with evict on close enabled.
+ *
+ *               9) Verify all datasets twice.
+ *
+ *              10) Close the file.
+ *
+ *              11) Open the file R/W and with evict on close enabled.
+ *
+ *              12) Verify all datasets twice.
+ *
+ *              13) Close the file.
+ *
+ *              14) Discard the file.
