Performance improvement regarding the iterators in libember

[GoogleCodeExporter]

We experienced performance problems with libember and therefore changed passing 
most of the iterator no longer by value, but by const-reference. This gives a 
boost about 10%-25% in our scenario. The reason, i think, is basically that a 
type-erased iterator is used, which needs dynamically allocated memory.

Please let me know your opinions about this issue - i will soon apply the patch 
if nobody disagree.
