[svn-r19714] Purpose:

    Add API and supporting code to allow single object flushes and refreshes.

Description:

    Added the following API calls:

    H5Dflush / H5Drefresh
    H5Gflush / H5Grefresh
    H5Tflush / H5Trefresh
    H5Oflush / H5Orefresh

    Each H5*flush API flushes the targeted object's metadata, 
    while each H5*refresh evicts all metadata related to an object 
    and reopens the object (re-loading needed metadata from disk).

    New files include src/H5Oflush.c, containing new internal H5O_* 
    functions used by the above API calls. Also, a test file and test 
    script template have been added, test/flushrefresh.c and 
    test/testflushrefresh.sh.in. There is not (yet) a corresponding 
    test script for windows as the current one isn't quite portable.

    Several H5C and H5AC-level functions have been added to support 
    single object flushing and eviction, and the previously committed 
    'metadata tagging' code has been tweaked slightly to pull H5AC__* 
    macros out of H5C.c and a few other fixes as necessary as well.

    Tag globality has been added to better encapsulate the meaning of 
    global tags in the H5C layer of the code. 

Tested:
