[svn-r13821]

Fixed a bug at copying shared reg_ref attribute. The ref values of an attribute
was not writen in file. The post_copy_file() at H5Oattr.c only updates the value
in memory. 

To fix the problem, we added H5O_shared_post_copy_file(), which delete the attribute
in file (with the incorrect value) and create an new attribute with the correct values.


I added the following functions:
H5Oshared.c:H5O_shared_post_copy_file(H5F_t *f, hid_t dxpl_id, H5O_t *oh, void *mesg); 
H5Oshared.h: H5O_SHARED_POST_COPY_FILE

and modified the following files to include shared_post_copy_file()
H5Oattr.c
H5Odtype.c
H5Ofill.c
H5Opline.c
H5Osdspace.c
