[svn-r21153] Description:

	Bring r21152 from trunk to 1.8 branch:

	Further patches for Jira 7638, to ensure that H5D/Aget_type will
be attached to the correct top file.  (This change to the library should
reverted when Jira 7638 is finally finished)

Tested on:
       FreeBSD/32 8.2 (loyalty) w/gcc4.6, w/C++ & FORTRAN, in debug mode
       Linux/32 2.6 (jam) w/PGI compilers, w/default API=1.8.x,
               w/C++ & FORTRAN, w/threadsafe, in debug mode
	(h5committested on trunk)

+ * Function:    H5T_patch_file
+ *
+ * Purpose:     Patch the top-level file pointers contained in dt to point
+ *              to f, if dt is a committed type.  This is possible because
+ *              the top-level file pointer can be closed out from under
+ *              dt while dt is contained in the shared file's cache.
+ *
+ * Return:      SUCCEED
+ *
+ * Programmer:  Neil Fortner
