[svn-r8879]
Purpose: New feature Description: New API H5Tencode and H5Tdecode. Given object ID, H5Tencode encodes object information into a binary form. H5Tdecode decode an object information in a binary form, reconstructs the object and return a new object ID. Solution: Use object header functions H5O_dtype_decode and H5O_dtype_encode to facilitate them. The encoded binary is exactly like object header information. This is the first step checkin. Will check in H5Sencode and H5Sdecode later. Platforms tested: h5committed and fuss. Misc. update: will update release.txt after 2nd step checkin.
