QLinkedList/QSet: add {const_,}reverse_iterator, {c,}r{begin,end}()
Now all Qt sequential containers consistently provide reverse iterators. The associative ones, by way of not returning std::pair from op*, can't just use std::reverse_iterator. They would miss .key() and .value() methods. So that has to wait for 5.7. The reverse versions of the new key_iterators can also just use std::reverse_iterator, but I'm afraid that after bikeshedding over keyRBegin() vs. rKeyBegin() vs. reverseKeyBegin() vs. rkbegin() vs. krbegin() (<-- of course, what else?), it would anyway be too late for 5.6, so defer, too. [ChangeLog][QtCore][QLinkedList/QSet] Added rbegin(), crbegin(), rend(), crend(), and reverse_iterator and const_reverse_iterator typedefs.
