[svn-r12708] Description:
Add the "use the latest version of the format" support to datatype messages. And a regression test to check that it's working. Also, found that we have been over-allocating space for compound datatype messages (when they have array datatypes or can use the latest version of the format) and trimmed the size back. Clean up datatype & dataspace encode/decode routines by having them allocate & release "fake" file structures, which gets them out of needing to "know" about the internals of file structures. Other minor whitespace/formatting cleanups, etc. Tested on: Linux/32 2.6 (chicago) Linux/64 2.6 (chicago2)
