[svn-r26559] Fix error in H5S_extent_copy (needs testing) - would not patch number of

elements selected with "all" slections nor reset sharing state.
Fix error in H5S__hyper_project_intersection algorithm.
Note there are still some code coverage assertions in the selection matching
algorithm - if you hit these try taking them out.
Note make check still fails in h5dump test (unrelated to this checkin).

Tested: ummon
