hdf5_ep

[svn-r1172] Purpose:
    New feature

Problem:
    The h5toh4 converter tester - testh5toh4, is set up to place output
    files in same directory as input files.  A difficulty comes up when
    the input files come off a write-protected media, such-as CDROM.

Solution:
    Rather than using "cd" to change directory and referencing files by
    short filename only, "input directory" and "output directory" are
    defined explicitly, and files are always referenced with pathnames
    included.  For cases when the converter generates the output filename,
    a copy of the input file is first placed in the "output directory".
    The copied input file is used by h5toh4 and then removed.

    On Solaris2.5, the following sequence of commands seemed to work fine:
    $ gunzip < hdf5-1.1.72.tar.gz | tar xf -
    $ chmod -R ugo-w hdf5-1.1.72
    $ mkdir build
    $ cd build
    $ ../hdf5-1.1.72/configure --enable-production --disable-debug \
    $   --with-hdf4=...  --with-zlib=...
    $ make check

    This change should allow the tester to be used when the hdf5 source
    is on a read only media like a CDROM.

Platform tested:
    Solaris2.5
