[svn-r8921] Purpose: new feature

Description:  This is the second step of checkin for encoding and decoding objects.
H5Tencode and H5Tdecode have been committed in the previous step.  H5Sencode
and H5Sdecode are checked in this time.

Solution: Given object ID, these functions encode and decode object information
into and from binary buffer and return new object ID.  They take advantage of the
existing codes of object header message and encode in the same format.

Platforms tested:  fuss and h5committest.

Misc. update:  RELEASE.txt
