[svn-r6705]
Purpose: Add new functions. Rewrite existing function. Description: Added H5get_vfd_handle and H5get_obj_ids. Rewrote H5get_obj_count: function description was incomplete and 2 (of 3) parameters were missing. Platforms tested: Safari, IE 5

+ <dd>Given the identifier of an open file, <code>file_id</code>,
+ and the desired object types, <code>types</code>,
+ <code>H5Fget_obj_count</code> returns the number of
+ open object identifiers for the file.
+ <p>
+ To retrieve a count of open identifiers for open objects in
+ all HDF5 application files that are currently open,
+ pass the value <code>H5F_OBJ_ALL</code> in <code>file_id</code>.
+ <p>
+ The types of objects to be counted are specified
+ in <code>types</code> as follows:
+ <center>
+ <table width=90% border=0>
+ <tr><td valign=top>
+ <code>H5F_OBJ_FILE</code>

+ </table>
+ </center>
+ Multiple object types can be combined with the
+ logical <code>OR</code> operator (<code>|</code>).
+ For example, the expression <code>(H5F_OBJ_DATASET|H5F_OBJ_GROUP)</code> would call for
+ datasets and groups.
