[svn-r4444] Purpose:
    Feature
Description:
    The H5Pset_fapl_split() used to assume both meta and raw files
    have the same prefix name.  This prohibited the option to specify
    the two files reside on different file systems.  E.g., having
    meta-file as /user/home/data1.meta and raw-file as /pfs/data1.raw.
Solution:
    Added feature that if the raw or meta extension string contains
    a "%s", it will be substituted by the filename given for H5Fopen
    or H5Fcreate.  This is same as the multi-file syntax.  If no %s
    is found, one is inserted at the beginning.  This is the previous
    behavior.
Platforms tested:
    Modi4 (parallel, serial) and eirene (parallel).
