[svn-r18376] Purpose: Fix bug 1733

Browse Source 
Description:
Support for expanding external links was not implemented in H5Ocopy, even though
a flag existed for H5Pset_copy_object to enable this.  This patch implements
this feature.

Tested: jam, amani, linew (h5committest); Fedora

@ -208,6 +208,9 @@ Bug Fixes since HDF5-1.8.0 release
Library
-------
- Added support for H5O_COPY_EXPAND_EXT_LINK_FLAG to H5Ocopy. External
links will now be expanded if this flag is set.
(NAF - 2010/03/05 - 1733)
- Fixed a bug where the library, when traversing an external link, would
reopen the source file if nothing else worked. (NAF - 2010/03/05)
- Fixed an intermittent bug in the b-tree code which could be triggered
