Tim Mayberry 97752e6a51 Use references rather than copying containers in libpbd xml code 
It is slightly surprising but there seems to be little difference to
performance with these changes. Possibly a slight improvement in "Create" test
with a large xml document(~5%).

Timing results before these changes with an optimized build using new XML perf tests:
