Merge branch 'master' of scm.dev.nokia.troll.no:qt/berlin-staging-1 into master-integration

* 'master' of scm.dev.nokia.troll.no:qt/berlin-staging-1: (22 commits)
  optimize qstring::simplified()
  Revert optimizations to QString::append
  unbreak QList::append() and co. again
  Implement bookmark manager widget.
  optimization: use QList::reserve() and QVector::reserve()
  amend "purge msvc.net and msvc2002 makespecs"
  Added QPlainTextEditor::anchorAt(const QPoint &pos)
  Fix memmory leak.
  Fix spacing.

  Fix broken Drag&Drop, reset and clear the model if we set new bookmarks.
  avoid double reallocations in appending operations
  avoid double reallocation in string-growing replace() case
  optimize qHash() some more
  optimize QList::mid()
  optimization: use QList::reserve() in QSet::toList()
  add QList::reserve()
