Quincey Koziol 14dcb6db33 [svn-r12736] Description: 
Add "use the latest format" support for dataspace object header encode/
decode routines and clean up format a bit for the latest format (new to 1.8.x
releases)

    Remove storing 'perm' parameter for array datatypes in memory and the file,
and add test to make certain that if any user applications are attempting to
store them, we get some reports back.  (Should be unlikely, since the RefMan
says that the parameter is not implemented and is unsupported).
    Carry those changes into the tests, etc.

    Clean up a bunch more compiler warnings.

Tested on:
    FreeBSD/32 4.11 (sleipnir) w/threadsafe
    Linux/32 2.4 (heping) w/FORTRAN & C++
    Linux/64 2.4 (mir) w/enable-1.6-compat

/*-------------------------------------------------------------------------
* Function: test_particular_fp_integer
*
* Purpose: Tests hard conversions from floating numbers to integers in
* a special situation when the source is "float" and assigned
* the value of "INT_MAX". A compiler may do roundup making
* this value "INT_MAX+1". When this float value is casted to
* int, overflow happens. This test makes sure the library
* returns exception in this situation.
*
* Also verifies the library handles conversion from double to
* signed char correctly when the value of double is SCHAR_MAX.
* The test makes sure the signed char doesn't overflow.
*
* This test is mainly for netCDF's request.
*
* Return: Success: 0
*
* Failure: number of errors
