hdf5

[svn-r17345] Purpose:

    Updating autotools

Description:

    Installed new autotools and used them to reconfigure HDF5.

    - Automake upgraded to 1.11
    - Autoconf upgraded to 2.64
    - bin/reconfigure script edited to use new versions (on jam), and
      run to generate new configure script and Makefile.in's.
    - configure.in script edited to add "_cv_" to all AC_CACHE_VAL strings
      (in order to comply with new autoconf standard).
    
Tested:

    Tested on machines jam, smirom, liberty, linew.
    Tested w/ features c++, fortran, parallel.
    Tested w/ compilers gcc, pgcc, icc.

    Further testing via Daily Tests should catch any other outliers. Upon
    passing DT's, I'll propogate the new tools into 1.8, hdf4, et cetera.
