Marc Mutz 7cba2acd2c qmake: replace QLinkedList with std::list 
This is in preparation of deprecating QLinkedList.

There is but one substantial change: Instead of copying the linked list,
we move it now, and instead of copying items between these two lists, we
use std::list::splice(), which just relinks nodes. It is a bit surprising
that the comment on the ProValueMapStack suggests references into the
container must remain stable, and then some code changes addresses by
making copies of the elements.

This was probably a bug waiting to manifest itself.

Since nothing else in qmake is using QLinkedList now, remove qlinkedlist.o
from the qmake build.
