 * Function:	H5Pset_alignment
 *
 * Purpose:	Sets the alignment properties of a file access property list
 *		so that any file object >= THRESHOLD bytes will be aligned on
 *		an address which is a multiple of ALIGNMENT.  The addresses
 *		are relative to the end of the user block; the alignment is
 *		calculated by subtracting the user block size from the
 *		absolute file address and then adjusting the address to be a
 *		multiple of ALIGNMENT.
 *
 *		Default values for THRESHOLD and ALIGNMENT are one, implying
 *		no alignment.  Generally the default values will result in
 *		the best performance for single-process access to the file.
 *		For MPI-IO and other parallel systems, choose an alignment
 *		which is a multiple of the disk block size.

 *      The special values of H5F_FORMAT_EARLIEST and H5F_FORMAT_LATEST can be
 *      used in the following manner:  Setting LOW and HIGH to H5F_FORMAT_LATEST
 *      will produce files whose objects use the latest version of the file
 *      format available in the current HDF5 library for each object created.
 *      Setting LOW and HIGH to H5F_FORMAT_EARLIEST will produce files that that
 *      always require the use of the earliest version of the file format for
 *      each object created. [NOTE!  LOW=HIGH=H5F_FORMAT_EARLIEST is not
 *      implemented as of version 1.8.0 and setting LOW and HIGH to
 *      H5F_FORMAT_EARLIEST will produce an error currently].
 *
 *      Currently, the only two valid combinations for this routine are:
 *      LOW = H5F_FORMAT_EARLIEST and HIGH = H5F_FORMAT_LATEST (the default
 *      setting, which creates objects with the ealiest version possible for
 *      each object, but no upper limit on the version allowed to be created if
 *      a newer version of an object's format is required to support a feature
 *      requested with an HDF5 library API routine), and LOW = H5F_FORMAT_LATEST
 *      and HIGH = H5F_FORMAT_LATEST (which is described above).
 *
 *      The LOW and HIGH values set with this routine at imposed with each
 *      HDF5 library API call that creates objects in the file.  API calls that
 *      would violate the LOW or HIGH format bound will fail.
 *
 *      Setting the LOW and HIGH values will not affect reading/writing existing
 *      objects, only the creation of new objects.
 *
 * Note: Eventually we want to add more values to the H5F_libver_t
 *      enumerated type that indicate library release values where the file
 *      format was changed (like "H5F_FORMAT_1_2_0" for the file format changes
 *      in the 1.2.x release branch and possily even "H5F_FORMAT_1_4_2" for
 *      a change mid-way through the 1.4.x release branch, etc).
 *
 *      Adding more values will allow applications to make settings like the
 *      following:
 *          LOW = H5F_FORMAT_EARLIEST, HIGH = H5F_FORMAT_1_2_0 => Create objects
 *              with the earliest possible format and don't allow any objects
 *              to be created that require a library version greater than 1.2.x
 *              (This is the "make certain that <application> linked with v1.2.x
 *              of the library can read the file produced" use case)
 *
 *          LOW = H5F_FORMAT_1_4_2, HIGH = H5F_FORMAT_LATEST => create objects
 *              with at least the version of their format that the 1.4.2 library
 *              uses and allow any later version of the object's format
 *              necessary to represent features used.
 *              (This is the "make certain to take advantage of <new feature>
 *              in the file format" use case (maybe <new feature> is smaller
 *              or scales better than an ealier version, which would otherwise
 *              be used))
 *
 *         LOW = H5F_FORMAT_1_2_0, HIGH = H5F_FORMAT_1_6_0 => creates objects
 *              with at least the version of their format that the 1.2.x library
 *              uses and don't allow any objects to be created that require a
 *              library version greater than 1.6.x.
 *              (Not certain of a particular use case for these settings,
 *              although its probably just the logical combination of the
 *              previous two; it just falls out as possible/logical (if it turns
 *              out to be hard to implement in some way, we can always disallow
 *              it))
 *
 * Note #2:     We talked about whether to include enum values for only library
 *      versions where the format changed and decided it would be less confusing
 *      for application developers if we include enum values for _all_ library
 *      releases and then map down to the previous actual library release which
 *      had a format change.
 *
