QHash/QSet: add erase(const_iterator)
This is the signature the functions have in C++11. For the std
containers, this is just convenience, but for Qt containers
with their implicit sharing problem, the combination of erase()
with constFind() can delay a detach until absolutely necessary.
[ChangeLog][QtCore][QHash/QSet] Added erase(const_iterator).
